Highway systems by country

This article describes the highway systems available in selected countries.

Map of Albanian Motorways as of 2014.

In Albania, major cities are linked with either new single/dual carriageways or well maintained State Roads marked as "SH" (Rrugë Shtetërore).

There is a dual carriageway connecting the port city of Durrës with Tirana, Vlorë, and partially Kukës.

There are three official Motorway segments in Albania marked with an "A" (Autostradë):

Thumanë–Milot–Rrëshen–Kalimash (A1),

Levan–Vlorë (A2),

and partly Tirane–Elbasan (A3).

Most rural segments continue to remain in bad conditions as their reconstruction has only begun in the late 2000s by the Albanian Development Fund [2].


About 1390 km of highways in Algeria are in service and another 1500 km are under construction.

In Australia, a highway is a distinct type of road from freeways, expressways, and motorways. The word highway is generally used to mean major roads connecting large cities, towns and different parts of metropolitan areas. Metropolitan highways often have traffic lights at intersections, and rural highways usually have only one lane in each direction. The words freeway, expressway or motorway are generally reserved for the most arterial routes, usually with grade-separated intersections and usually significantly straightened and widened to a minimum of four lanes. The term motorway is used in some Australian cities to refer to freeways that have been allocated a metropolitan route number. Roads may be part-highway and part-freeway until they are fully upgraded. The Cahill expressway is the only "named" expressway in New South Wales, which opened in 1954, the first in the region.


In contrast to Germany, according to a 2002 amendment of the Austrian federal road act, Bundesstraßen is the official term referring only to autobahns (Bundesstraßen A) and limited-access roads (Schnellstraßen, Bundesstraßen S). The administration of all other former federal highways (Bundesstraßen B) has passed to the federal states (Bundesländer).

Therefore, officially classified as Landesstraßen, they are still colloquially called Bundesstraßen and have retained their 'B' designation (except for Vorarlberg), followed by the number and a name. They are marked by a blue number sign.


Belgium has the second highest density highway network in Europe after the Netherlands, at 54.7 km per 1000 km². Most Belgian highways have three lanes with a few exceptions like the ring roads around Brussels and Antwerp which have five or six lanes in some stretches. Belgium is situated at a crossroads of several different countries, and its highways are used by people of many nationalities. Belgian highways are indicated by the letter "A" and a European number, with E numbers being used most often. Roads that are (part of) a ring road around a city or a town are usually indicated by an R number. Many of the highways in Belgium are illuminated at night, since there is a surplus of nuclear-powered electricity during off-peak hours.

Bosnia and Herzegovina

As for Bosnia and Herzegovina, the Pan-European Corridor Vc Motorway, BudapestOsijekSarajevoPloče, is one of the most significant and project of the highest priority; in Bosnia and Herzegovina it coincides with A1 Motorway. The construction works on the road have already begun, but intensified beginning of the construction will be a key starter of economic and social activities, and will enable Bosnia and Herzegovina to be connected to main European traffic network, as well as to global European economic and social structure.

Construction of the motorway, whose total length is 340 km, will provide: rational connecting to neighboring countries and regions; stabilizing and developing effects will be reached; transport conditions and quality of life improvement; economy competitiveness enhancement; new projects launched and national and international private investments enhancement.


In Brazil, highways (or expressway/freeway) are named "rodovia", and Brazilian highways are divided in two types: regional highways (generally of less importance and entirely inside of one state) and national highways (of major importance to the country). In Brazil, rodovia is the name given exclusively to roads connecting two or more cities with a sizable distance separating the extremes of the highway. Urban highways for commuting are uncommon in Brazil, and when they are present, they receive different names, depending of the region (Avenida, Marginal, Linha, Via, Eixo, etc.). Very rarely names other than "rodovia" are used.

Regional highways are named YY-XXX, where YY is the abbreviation of the state where the highway is running in and XXX is a number (e.g. SP-280; where SP means that the highway is running entirely in the state of São Paulo).

National highways are named BR-XXX. National highways connects multiples states altogether, are of major importance to the national economy and/or connects Brazil to another country. The meaning of the numbers are:

  • 001–100 – it means that the highway runs radially from Brasília. It is an exception to the cases below.
  • 101–200 – it means that the highway runs in a south–north way.
  • 201–300 – it means that the highway runs in a west–east way
  • 301–400 – it means that the highway runs in a diagonal way (northwest–southeast, for example)
  • 400–499 – another exception, they are less important highways and its function is to connect a city to an arterial highway nearby

Often, Brazilian highways receive names (famous people, etc.) on top of their YY/BR-XXX designation (example: SP-280 is also known as Rodovia Castelo Branco).


The strategic location of the country on the Balkan Peninsula is decisive for the fact that 4 out of 10 land Pan-European corridors run through it.

Highways in Bulgaria are dual carriageways, grade separated with controlled-access, designed for high speeds. In 2012 legislation amendments defined two types of highways: motorways and expressways. The main differences are that motorways have emergency lanes and the maximum allowed speed limit is 140 km/h,[1] while expressways don't and the speed limit is 120 km/h.[2]

As of December 2018, 800.5 km (497 mi) of motorways are in service, with another 38.2 km (24 mi) being under various stages of construction. More than 500 km (311 mi) of motorways are planned. Also, several expressways are planned.


Highway 401 by 401-DVP

  • In Canada, there is no national standard for nomenclature, although in non-technical contexts highway appears to be most popular in most areas. The general speed limits on most Canadian highways range between 80 and 110 km/h (50 and 68 mph) on two-lane highways, and between 90 and 110 km/h (56 and 68 mph) on multi-lane, divided highways. In 2014 the Province of British Columbia raised the speed limit on some portions of its multi-lane, divided highways to 120 km/h.
  • Canada is the second largest country in the world in terms of land area, though it only has 1,350,581 kilometers (839,212 mi) of paved roads. This is far less highway and road distance than the United States, which is smaller, but has more than 6,000,000 kilometres of paved roads and highways. However, Canada still has many more roads and highways than Russia, the largest country in the world in land area, with an estimated just 336,000 kilometres (208,000 miles) of paved roads.
  • The most extensive freeway network in Canada is in the well-populated southeastern Canada, linking southern Ontario, southern Quebec, Nova Scotia, New Brunswick, and the United States. This makes the freeway network there very well-travelled, requiring these routes to be well-maintained to overcome the frequently harsh winter weather, wide enough to accommodate the high traffic volumes that they carry in large metropolitan areas (such as around Toronto, Montreal, Ottawa, and Detroit) in order to reduce the economic problems and frustrations that result from heavy traffic congestion, and also be safe enough to reduce the number of vehicle accidents.
  • Ontario has some of the oldest and busiest freeways in North America. It has all public roads legally defined as highways, though provincially managed roads are known legally as Provincial Highways. In day-to-day usage, the term highway is used for provincial routes or freeways. It is also common for surface routes to be referred to by number (e.g. "Take Highway 10 from Mississauga to Owen Sound"), especially by older generations. The words freeway or expressway are sometimes used to refer to controlled-access, high-speed, grade-separated highways such as the 400-series highways, the Gardiner Expressway, the Don Valley Parkway, the Conestoga Parkway, or the E.C. Row Expressway. The only highway officially labelled as a freeway is the Macdonald–Cartier Freeway, usually known as Highway 401, or simply "the 401", which is North America's busiest freeway, as well as one of the widest in the world at 18 through lanes in the section passing through Toronto.[3][4] The Queen Elizabeth Way was the first intercity divided highway in North America. [5] Nearly all highways in Ontario use parclo interchanges, which were developed by the province. Parclos are used to avoid weaving and to maximize efficiency and safety.
  • In Quebec, major highways are called autoroutes in French, and expressways or autoroutes in English.
  • Nova Scotia numbers its highways by the trunk routes they parallel. For example, Highway 107 parallels Trunk 7. This, to a lesser extent, also applies in Ontario (e.g. Highway 410 and Highway 420 parallel Highway 10 and Highway 20.) Nova Scotia also numbers its highways according to usage: main arterial highways are in the 100s, secondary or old arterial highways are numbered in the double digits from 1 to 28, and collector roads are numbered in the triple digits starting at 200.
  • The Trans-Canada Highway (or Trans-Canada) is a highway that crosses all of Canada from east to west and enters all ten provinces. The Trans-Canada ranges from a two-lane highway as it runs through the mountains of British Columbia, a multi-lane at-grade divided highway with occasional grade separation as it travels through the western provinces, a two-lane at-grade highway again as it passes through the sparsely populated areas of northern Ontario, and a multi-lane freeway as it travels through southern Ontario, southern Quebec, New Brunswick, and Nova Scotia. There are three or more ferry routes along the Trans-Canada, which allows it to connect to Newfoundland, Prince Edward Island, Haida Gwaii, and Vancouver Island. The Confederation Bridge provides an alternative route from New Brunswick to Prince Edward Island.

Since the Trans-Canada Highway is not yet a divided, multi-lane freeway for its entire length, the section that crosses the western provinces and northern Ontario is considered to be more of an equivalent to the U.S. Route highway network in the neighboring United States. On the other hand, southern Ontario's 400-series freeways, Quebec's autoroutes, New Brunswick's portion of the Trans-Canada, and Nova Scotia's 100-series highways are provincial equivalents to the American Interstate Highway System. The Canadian freeways interconnect with each other across provincial lines, and also with the American Interstate system. For example, freeways in Québec connect Montreal with the American border, and thence Interstate 87 continues from there to New York City, and likewise, Toronto is connected to the border by Ontario freeways, and thence by Interstate 190 to Buffalo, New York.

The province of Ontario has one of the finest road networks in the world. Highway (freeway) 407 ETR, is one of the most modern toll freeways in the world. 407 ETR has automatic toll collection system in place. Transponders are required to travel on 407 ETR; if a vehicle does not carry a transponder, the vehicle license plate is photographed, and the owner of the vehicle is billed. This rule applies to all vehicles from throughout North America.


Chile has a large highway coverage which connects the whole country with the exception of the Magallanes region.

China, People's Republic

"Highways" in China, more often than not, refer to China National Highways. The fully controlled-access, multi-lane, divided routes are instead called expressways. As of 2017, there were 5.98 million km of highways and 131,000 km of expressways in China; both total lengths are the longest in the world.

In Mainland China, private companies reimbursed through tolls are the primary means of creating and financing the National Trunk Highway System (NTHS).

Expressways are lumped with first-grade G-prefixed guódào (国道, or "national highway") or A-prefixed first-grade expressways in major municipal cities. All roads in the NTHS and most A-prefixed roads are expressways.

  • M-prefix: National (Trunk) Expressways (planned)
  • G-prefix: National highways (typically expressways)
  • A-prefix: Municipal highways (typically expressways)
  • S-prefix: Provincial highways
  • X-prefix: County highways
  • Y-prefix: Rural roads
  • Z-prefix: Special use roads (e.g., airport expressways)

Some highways are numbered with a leading zero (e.g. G030).

The term Freeway during the 1990s was used on a few expressways (such as the Jingshi Freeway). The term freeway has since been replaced with expressway on all signs in China. The Chinese name for expressways is 高速公路; in pinyin, it is gāosù gōnglù, which literally means "high speed public road".

Signs on the National Highways (G-prefix) are green, while on the lower-grade highways and urban expressways (A-prefix) are blue.

Hong Kong

In Hong Kong, the type of high speed roads is referred to as expressway, but some are named as highways or roads ('Yuen Long Highway', 'Tolo Highway', 'Tsuen Wan Road', 'Tuen Mun Road', etc.). Some others are named corridors and bypasses.

In Colombia are managed by the Colombian Ministry of Transport through the National Institute of Roads. Colombia's road infrastructure is still very underdeveloped with most of the highways presenting a two lane road for outbound and inbound traffic. Some exceptions are the Autopista Norte, linking Bogota and the towns of Tunja and Sogamoso and the Highways of the Valle del Cauca, an infrastructure improvement project started about a decade ago which has not yet been entirely finished. Several dual-carriage ways also link cities like Medellin, Pereira, Manizales and Armenia.

Nowadays, the direct public funding on highways is increasing, focused mostly in connecting Colombia's agricultural and industrial heartland with its Caribbean and Pacific ports through twinning existing roads and the construction of 5,892 km of roads.[6]

The most important projects under negotiation or construction are La Ruta del Sol (the Sun Road), a 4-lane highway between Bogota and the Caribbean coast; and the Highway between Bogota and Buenaventura (Colombia's largest and busiest port) which includes a 9 km tunnel.


Croatia has 11 highways and 13 expressways. The earliest highway in Croatia was built in 1971. The word highway is a common Croatian translation of the term autocesta, which describes a toll highway similar to a freeway or an Autobahn.

Czech Republic

The Czech Republic has 17 motorways. The construction of the earliest Czech highway (D1) between Prague and Brno was initiated in 1939, but was twice interrupted and reached Brno only in 1980. The word highway is a common Czech translation of the term dálnice, which describes a toll highway similar to a freeway or an Autobahn.


With the completion of the extremely long highway bridge-tunnels of Great Belt Fixed Link in 1998 and Øresund Bridge in 2000, continental Europe was finally connected by road and rail with capital city Copenhagen and Sweden. This includes the Swedish highway and railroad system. The bridge-tunnels are all interconnected with major Danish highways and completes a continuous international road connection from northern Sweden to Gibraltar at the southern edge of Spain and Messina, Italy, at the southern tip of the Italian "boot".

The 18 kilometre Fehmarn Belt Fixed Link has commenced construction in 2017, planning to link Zealand (with Copenhagen) to northern Germany by 2028.


The national highways in Finland are numbered 1-29 and are in total 9,000 km long. This number system originates from 1938. There are motorways for 881 kilometres around the largest cities, specially down south near the capital Helsinki. Highways numbered 1-6 are the main connection roads in Finland.


France has a national highway system dating back to Louis XV (see Corps of Ponts et Chaussées). The chaussées constructed at this time, radiating out from Paris, form the basis for the "routes nationales" (RN), whose red numbers differ from the yellow numbering used for secondary "routes departementales". The RNs numbered from 1 to 20 radiate from Paris to major ports or border crossings. More recently (after the Second World War), France has constructed Autoroutes, ex. A6-A7 which is call Autoroute du soleil, superhighways (usually toll) with a speed limit of 130 km/h (110 in rainy conditions or urban areas).


Aside from highways bearing the Autobahn designation, Germany has many two- and four-lane roads. Federal highways not known as autobahnen are called Bundesstraßen (Bundesstrassen) and, while usually two-lane roads, they may also be four-lane, limited-access expressways of local or regional importance. Unlike the Autobahnen, though, Bundesstraßen (marked by black numbers on a yellow background) mostly have speed limits (usually 100 km/h, but occasionally higher on limited-access segments, and lower in urban areas or near intersections).


Hungary has 7 major motorways ("autópálya"):

  • M0 is a quasi-circular highway for the traffic bypassing Budapest. It is divided in 4 sectors: Southern (links motorways M1, M7, M6 and M5), South-eastern (links Motorway M5 and Main Road nr. 4), Eastern (links Main Road nr. 4 and Motorway M3), Northern (links Main Road nr. 2 with the Megyeri Bridge) and Western (to be finished in 2015; will link main roads 11, 11 and Motorway M1). The total length will be around 100 km.[3]
  • M1: links Budapest and the north-western border with Austria (Hegyeshalom), then continues its way toward Vienna. The total length is around 170 km.
  • M3: links Budapest and the north-eastern city of Miskolc (M30 branch), eastern cities of Nyíregyháza (M3) and Debrecen (M35 branch). Provides links toward Slovakia, Ukraine and Romania. It has a total length of around 250 km.
  • M5: links Budapest and the southern city of Szeged, then the Serbian border (Röszke). It provides a connection to Southern Europe by route E75 and also links to route 68 in Romania. M5 motorway has a length of around 140 km.[4]
  • M7: links Budapest and the southern shore of Lake Balaton, then continues its way toward Croatia and Slovenia. Its length is about 230 km.
  • M6: links Budapest and Dunaújváros, now extended to the southern city of Pécs. The original length was around 60 km.[5]

Also, there are other smaller motorway sections that will be linked to the national motorway network in the future. See here an animation of Hungarian motorway developments (past, present and future): "Térkép animáció". Motorways usually have 2 traffic lanes and an emergency lane on each direction, divided by a green zone and metallic rail. The speed limit is 130 km/h.

Expressways usually have no dividing lane in the middle, but sometimes have a metallic rail. The number of lanes is one per direction, with sections of 1+2 lanes (for easier overtaking). The speed limit is 110 km/h. Motorways and expressways cannot be used by vehicles that are not able to reach 60 km/h. There is a toll on all motorways, except M0. Trucks and buses have a separate toll system. ([6])

Those who wish to travel on these roads have to buy a sticker. Controversially, there is no option to buy a one-day or one-time pass for passenger cars.

Main roads usually have one lane per direction, no dividing rail. The speed limit is 110 km/h.

County roads have less traffic then main roads, the speed limit is 90 km/h.


National Highway (India) (100,087 kilometres (62,191 mi)),

Nh 7
National Highway 7 (India) (longest Highway of India), India.

In India, 'Highway' refers to one of the many National Highways or State Highways that run up to a total length of about 96,260 km consisting mostly of two-lane paved roads, changing into higher lanes mostly around cities. National Highways are designated as NH followed by the number. As of 2009, the major cities in India – Ahmedabad, Pune, Bangalore, Hyderabad, Mumbai, Chennai, Kolkata, and Delhi – are connected by the Golden Quadrilateral or North-South and East-West Corridor, that consists of 4 to 6 laned roads. Other major cities are connected to it by the National Highways.

An expressway refers to any access controlled road with grade-separated intersections and make up a very small portion of India's highway network, at about 1454.4 km in length.[7] Expressways are separate from the highway network, except for the Delhi-Gurgaon Expressway, which is part of NH 8. Agra-Lucknow Expressway is the longest expressway more than 300 km in India after its inauguration on 21 November 2016 replacing Yamuna Expressway 165 km, cost ₹150 billion (US$2.2 billion).


The Indonesian national route system exists solely on Java. Examples of roads include Jakarta's Inner and Outer ring roads, the Cipularang Toll Road in West Java connecting Jakarta and Bandung, and the partially complete Trans-Java toll road.


The Republic of Ireland has the 6th densest motorway network in Europe. 'N' road or 'R' road. The maximum speed is 120 km/h on motorways. The main Inter Urban route Motorways connecting Dublin by motorway to the cities of Cork, Limerick, Waterford and Galway, as well as other projects, has increased the total motorway network in the state to approximately 1,017 kilometres (632 mi).

Modarres Highway

In Iran the term highway ~ commonly known as autobahn (in Persian: اتوبان /بزرگراه), is applied to roads that are constructed by particular standards. The conventional speed limit of 120 km/h is in place for most highways. There are two types of highway in Iran:

  1. Inner cities highways: They can be found in larger cities such as Tehran. The main purpose of them is to prevent congestion and pass traffics through cities.
  2. Between cities highway: They connect different part of the country together.

The A3 in Italy.

In Italy the term highway can be applied to superstrada (can be translated as expressway and it is toll free) and autostrada (Italian term for motorway: the most part of the system is mandatory toll). Italy was the first country in the world to build such roads, the first one being the "Autostrada dei Laghi" (Autostrada of the Lakes), from Milan to Varese, built in 1921 and finished in 1924. This system of early motorways was extended in the early 1930s till the early 1970s. Nowadays the Autostrade is a comprehensive system of about 6.500 km of modern motorways where the maximum speed limit is 130 km/h.


The expressways, or kōsokudōro (high speed roads), of Japan are made of a huge network of freeway-standard toll roads. Once government-owned, they have been a turned over to private companies. Most expressways are four lanes with a central reservation, or median. The speed limits, with certain regulations and great flexibility, usually include a maximum speed of 100 km/h, and a minimum speed of 50 km/h.


The highest level of major roads in Malaysia, expressway (lebuhraya), has full access control, grade separated junctions, and mostly tolled. The expressways link the major state capitals in Peninsular Malaysia and major cities in Klang Valley.

Highway is lower level with limited access control, some at-grade junctions or roundabouts, and generally with 2 lanes in each separated direction. These are generally untolled and funded by the federal government, hence the first one is called Federal Highway linking Klang and Kuala Lumpur.

The trunk roads linking major cities and towns in the country are called federal trunk roads, and are generally 2 lanes single carriageway roads, in places with a third climbing lane for slow lorries.

New Zealand

Auckland State Highway One
State Highway 1 in South Auckland, New Zealand

In New Zealand, both motorway and an expressway have at least two lanes of traffic in either direction separated by a median, with no access to adjacent properties. The distinction depends on the type of traffic allowed to use the route. Non-vehicular traffic and farm equipment are prohibited from motorways, while pedestrians, cyclists, tractors, and farm animals are legally entitled to use expressways such as the Waikato Expressway south of the Bombay Hills and the Tauranga expressway system, although this is rare. New Zealand's main routes are designated state highways as they are funded by the central government. State Highway 1 is the only route to run through both the North and South Islands, and runs (in order north–south) from Cape Reinga to Wellington in the North Island, and from Picton to Bluff in the South Island. State Highways 2–5 are main routes in the North Island, State Highways 6–9 in the South Island, and state highways numbered from 10 onwards are generally found in numerical order from north to south. State highways usually incorporate different standards of roads, for example, State Highway 1 from Auckland to Hamilton incorporates the Northern and Southern Motorways in the Auckland area, the Waikato Expressway, and a rural road before passing through the streets of Hamilton. The term freeway is rarely used relating to New Zealand roads.


The Autosnelweg system is in constant development. Most of its parts are owned and funded by the government, but in recent times Public-private partnership come more and more into practice, such as in a part of the A59 between Oss and 's-Hertogenbosch. The Netherlands has the highest density highway network of Europe at 56.5 km per 1000 km², followed by Belgium. The 'Autosnelwegen', the main corridors, are designated with an A while secondary connecting roads have an N number. Sections of the A network are also part of the International E-road network in connecting with neighboring Belgium, Germany and England, the latter by ferry. The speed limit is 130 km/h, unless noted otherwise, and 120 km/h, 100 km/h or 80 km/h on various locations. This is done to reduce exhaust emissions and to limit noise to surrounding residential areas.

North Macedonia

Total length of the Macedonian motorways as of Spring 2019 is 317 km, with another 57 km being under construction. There are plans to extend the network with works planned to start in 2020. Major sections are A1 (E-75), which connects the northern (Serbia) to the southern border (Greece), A2 (E-65) connects Skopje, Tetovo and Gostivar (Kicevo and Ohrid by 2021). A3 connects Skopje to the eastern town of Stip.


Norway has a national highway system, numbered 2-899. Some main highways are also European highways and have an E before the number. The highways are often relatively narrow and curvy. Near the larger cities, especially around Oslo and Trondheim, there are motorways. Norway has also been engaged in recent decades in boring some extremely long highway tunnels through the mountain ranges, and some of these, now the world's longest, are so long that they have hollowed-out caverns in the midst of them for motorists to stop and take rests.



Pakistan has its own network of highways and motorways. Motorways extending from M1 to M10 will eventually connect whole length of the country from Peshawar to Karachi. The M2, the first motorway, was built in 1997 with the contract being awarded to the Korean firm Daewoo. It linked the federal capital Islamabad with Punjab's provincial capital Lahore. The network was then extended to Sargodha and then to Faisalabad with the M3. M1 highway to the Khyber Pakhtunkhwa's capital Peshawar had been completed in October 2007. M4, M5, M6, and M7 have been planned and also being built by local and foreign firms. This will connect Faisalababd, Multan, Dera Ghazi Khan, Rotadero (Larkana) to Karachi. N5 links Karachi to other cities. Entry on all Pakistan highways is restricted to fast moving wheelers only. Slow-moving traffic and two wheelers (such as motorcycles and bicycles) are not allowed and construction and agricultural machinery is also restricted. Highway Police personnel use heavy motor bikes and fast moving Range Rovers for patrolling and are quite good at maintaining the traffic system. M9 and M10 are also functional now that connect Karachi to Hayderabad. The LSM (Lahore Sialkot Motorway) which is 103 km is under construction and will be completed by 2010. Expressways are similar to motorways with lesser access restrictions and are owned, maintained and operated either federally or provincially.

Pakistan's Motorways are patrolled by Pakistan's National Highways & Motorway Police (NH&MP), which is responsible for enforcement of traffic and safety laws, security and recovery on the Pakistan Motorway network. The NH&MP use SUVs, cars and heavy motorbikes for patrolling purposes and uses speed cameras for enforcing speed limits.

Polish public roads are grouped into categories related to administrative division. Poland has 383,313 km (238,180 mi) of public roads, of which 122,080 km (75,860 mi) are unpaved (2008):

  • National roads: 18,520 km (11,510 mi)
  • Voivodeship roads: 28,536 km (17,730 mi), 61.4 km (38 mi) unpaved
  • Powiat roads: 126,924 km (78,870 mi), 12,539 km (7,790 mi) unpaved
  • Gmina roads: 209,333 km (130,070 mi), 109,478 km (68,030 mi) unpaved

Polish motorways and expressways are part of national roads network.


Romania currently has five operational highways, summing up to 807 km; They are now being extended and additionally, another four motorways are planned to be built by 2020.

The orange highways will run next to the green European roads.

There are no tolls for using the motorways in Romania, except Cernavodă Bridge over the Danube on the A2. Nevertheless, every Romanian car that uses a motorway or a national road in Romania must pay a toll, called rovinieta. Since a few years rovinieta is electronic, meaning that the sticker on the windscreen disappear.


Russia has many highways, but only small number of them are currently motorways. Examples of Russian motorways are Moscow and Saint Petersburg Ring Roads. Highways and motorways are free in Russia and only two motorways, Western High Speed Diameter and Moscow-Saint Petersburg toll motorway, currently under construction, will be first Russian toll motorways. Russians themselves often translate the Russian name for highway (Автомобильные дороги=automobile roads) into motorway in English, which is not a correct English name, it should be highway.

Saudi Arabia

Saudi Arabia has a total highway length of 73,000 km. Highways in Saudi Arabia vary from ten laned roads to small four laned roads. The city highways and other major highways are well maintained such as the roads in Riyadh. The roads are constructed so they resist the summer's extremely high heat and do not reflect the strong sun. The outer city highways such as the one linking from coast to coast are not as great as the inner-city Riyadh highway is fasts highways in KSA but the government is now working on rebuilding those roads.

Some of the important inter-city highways include:

  • Dammam - Khafji Highway (457 120 km/h)

The highways in Serbia are classified as IA state roads and common name for highway is auto-put which functions based on toll pay system and controlled access. Serbia currently has 782 km of total length of highways (and total length of public roads is 40,845 km), while 1,154 km are planned. Because of its geographical position, it is very important for transit of capital, goods and services though Europe and Balkans, especially. As well it is one of most important countries on Balkans for Pan-european corridors (E65, E70, E75, E80, E661, E662, E761, E763, E771, E851).

The signs on Serbian highways are green colored and speed limit is 130 km/h. The history of Serbian highways starts with socialist Yugoslavia, when increased production influenced on enlargement of transit on public roads. The first highway to be built was brotherhood and unity highway that encompassed Slovenia, Croatia, Serbia and Macedonia. That highway was part of the pan-european corridor X and was built around 1970-ties.


Bukit Timah Expressway
The Bukit Timah Expressway in Singapore.

The expressways of Singapore are all dual carriageways with grade-separated access. They usually have three lanes in each direction, although there are two- or five-lane carriageways in some places. There are nine expressways, with the newest one, the Marina Coastal Expressway which is constructed under modern technology under the water.

Construction on the first expressway, the Pan Island Expressway, started in 1966. The other expressways were completed in stages, with the first phase of the Kallang-Paya Lebar Expressway being the most recently completed, in 2007. Today, there are 148.9 kilometres of expressways in Singapore.


The highways in Slovakia are divided into motorways (diaľnica) and expressways (rýchlostné cesty). The first modern highway in Slovakia should have been in the 30s planned motorway connecting Prague with northern parts of Slovakia; however the construction of the Slovak motorways was not started until 1970s.

As of December 2018, 486 km (302 mi) of motorways and 265 km (165 mi) of expressways are in service, with another 120 km (75 mi) being under various stages of construction.

South Africa

Colloquially, the terms "freeway", "highway", and "motorway" are used synonymously. The term "expressway" is not common in South Africa. A freeway, highway or motorway refers to a divided dual carriageway with limited access, and at least two lanes in either direction. A central island, usually either with drainage, foliage, or high-impact barriers, provides a visible separation between the carriageways in opposite directions. As in the United Kingdom, Ireland, Australia, and Japan, South Africans drive on the left-hand side of the road and nearly all steering wheels are on the right-hand side of vehicles.

Freeways are designated with one of three labels: N (in reference to national roads), R (short for "route", in reference to provincial roads), and M (in reference to metropolitan roads). This has more to do with the location of a road and its function than anything else. In addition, "N" roads usually run the length of the country over long distances, "R" roads usually inter-connect cities and towns within a province, and "M" roads carry heavy traffic in metropolitan areas. Route markings also determine who paid for the road: "N" was paid for by national government, "R" by provincial government, and "M" by local government. In recent years, some "R" roads have been re-designated as "N" roads, so that control and funding comes from the South African National Roads Agency.

South Korea

Expressways in South Korea were originally numbered in order of construction. Since August 24, 2001, they have been numbered in a scheme somewhat similar to that of the Interstate Highway System in the United States:

  • Arterial routes are designated by two-digit route numbers, with north–south routes having odd numbers, and east–west routes having even numbers. Primary routes (i.e. major thoroughfares) have five and zero as their last digits respectively, while lesser (secondary) routes have various final digits.
  • Branch routes have three-digit route numbers, where the first two digits match the route number of an arterial route.
  • Belt lines have three-digit route numbers where the first digit matches the respective city's postal code.
  • Route numbers in the range 70-99 are not used in South Korea and are reserved for designations in the event of Korean reunification.
  • The Gyeongbu Expressway kept its Route 1 designation, as it is South Korea's first and most important expressway.


A7 algeciras
An older highway in Spain

Spain's national highway system dates back to the era of King Carlos III. The roads built at this time, radiating from Madrid, form the basis for the carreteras nacionales radiales, numbered clockwise from I to VI, which radiate from Madrid to major ports or border crossings. In the 1960s Spain started to construct autopistas (toll highways) and autovías (freeways), and in 2013 had 16,583 km of highways, the biggest network in Europe and the third in the world, only after the USA and China.

Sri Lanka

Southern Expressway (E01) is the first expressway in Sri Lanka. It travers from Kottawa (township in Suburban Colombo) to Matara (126 km) and the construction of the section from Kottawa to Pinnaduwa (Galle) was completed as a dual Expressway with 4-lane facility and declared open in November 2011. Galle Port access road has been built to connect Galle city to Pinnaduwa interchange. The design speed of this Expressway is 120 km/h. The operation speed of the Expressway is 100 km/h. The Southern Expressway will be extended up to Hambantota connecting Mattala Rajapaksa International Airport and the Magampura Mahinda Rajapaksa Port.

The second expressway to be declared open in Sri Lanka was the Colombo - Katunayake Expressway (E03) that was opened for public from October 2013, which also connects Sri Lanka's premier international airport Bandaranaike International Airport with capital Colombo.

Colombo Outer Circular Expressway (E02), which is currently under construction, is designed to link the major expressways connected to Sri Lanka's commercial hub, Colombo, bypassing the traffic within the city limits.


The first freeway in Sweden was built between the cities of Malmö and Lund in the Skåne County in southern Sweden. The Swedish roads are divided in three classes; Motorväg, which is a 4-8 lane motorway with the speed limit of 110–120 km/h. Riksväg, which is a state highway with 2-4 lanes. The Riksväg has a speed limit of 70–100 km/h. The last road is the Länsväg, which is a "county route" with 2 lanes and 70–90 km/h in speed limit. The authority which is responsible for the roads in Sweden is Vägverket.


The term Autobahn (German) / Autoroute (French) / Autostrada (Italian) is used for normal highways where there is a central physical structure separating two different directional carriageways. This is often translated into English as motorways.

In express routes where there is no central physical structure separating two different directional carriageways, but crossings are still motorway-like otherwise, and traffic lights are not present, the road is instead called an Autostrasse / Semi-autoroute / Semi-autostrada, usually translated into English as an expressway. Those often have a lower speed limit than motorways.


The construction of Taiwan's national highways began in 1971 and the design is heavily based on the American Interstate Highway System. The Northern section between Keelung City and Zhongli City (now Zhongli District, Taoyuan) was completed in 1974. The construction of the first freeway (No. 1) was completed in 1978. The freeway runs from the northern port city cf Keelung to the southern port city of Kaohsiung. There was an 8.6 km branch (No. 1A) connecting the Taiwan Taoyuan International Airport.

Construction on the other freeways began in the late 1980s. The north section of the second north–south freeway (No. 3) between Xizhi City and Hsinchu City was completed in 1997. The No. 1A Branch was extended to link No. 3 Freeway at Yingge, and renamed as No. 2 Freeway. Three other short freeways (No. 4, No. 8, and No. 10) were built to link the two north–south freeways in Taichung County (now part of Taichung City), Tainan County (now part of Tainan City), and Kaohsiung County (now part of Kaohsiung City), respectively. The entire No. 3 Freeway was completed in January, 2004.

To ease the congestion of No. 1 Freeway in the Taipei metropolitan area, a 20 km elevated bridge was built in 1997 on top of the original freeway between Xizhi City and Wugu, to serve as a bypass for traffic not exiting/entering the freeway within the city limits of Taipei.

The construction of a freeway connecting the Taipei metropolitan area and Yilan County began in 1991 and was completed in June 2006. It includes a 12.9 km tunnel (Hsuehshan Tunnel), which is the fifth longest road tunnel in the world. An extension from Yilan County to Hualian County is planned. However, its construction is being delayed due to environmental concerns.


Turkey's main highway is E80 (former E5) runs from Edirne to the capital Ankara.

United Kingdom

In the United Kingdom, the terms used for vehicular highways other than motorways include main road, trunk road, 'A' road / 'B' road, 'C' road, and unclassified road; they may additionally, where appropriate, be described as dual carriageways. However, in the law of England and Wales the term public highway includes all public rights of way regardless of the kind or amount of traffic they allow, including streets and public footpaths for pedestrians.[8] The term also includes bridleways, which are for pedestrians, equestrians, and cyclists, as well as by-ways open to all traffic (for all of those users, plus vehicular traffic).

In England and Wales, the public is said to have a "right of way" over a highway. This means that, subject to statutory restrictions, the route (or "way") must be kept clear to allow travel by anyone who wishes to it. At common law, it is unlawful to obstruct a highway or to interfere with its lawful use. However, many statutory provisions provide powers to do so (for instance. to carry out roadwork).

Many public highways in the UK have a private owner. That is, someone can prove "title" to them, either by being the registered owner or by having conveyances showing exactly how the land has been bought and sold over a long period of time. Such ownership in no way affects the public highway rights, since the relevant "highway authority" (usually a local authority or the Highways Agency in England and Wales, or Amey Highways in Scotland) is deemed to own the surface of the highway, despite someone else's ownership of the land it passes over or under.

Rights-of-way exist over all highways maintained at the public expense (the majority of roads) and also over some other ways which are not so maintained, on the principle of "once a highway, always a highway". In such cases, landowners must allow public use for "passing and repassing".

A right-of-way may be created by custom (by the way being used for a long period of time) or under the relevant Sections of the Highways Act of 1980. A right-of-way may be extinguished or diverted in a number of ways, such as by an Act of Parliament, by a magistrates' stopping-up or diversion order, or by powers given to principal local authorities. For instance, under the Channel Tunnel Rail Link Act of 1996, authority was given for the builder of this railway link to stop up certain highways that are mentioned in Schedule 3 of the act.

The opposite of a highway is a private road or pathway over which no rights-of-way exist. Any use of such private ways is subject to the consent of the owner of the land.

Richard Mabey poses the origin of the word "highway" back to the Romans in his book "The Roadside Wildlife Book", 1974: "Daniel Defoe, writing in the 1720s, describes the Fosse Way as being raised eight or nine feet in many places. Between AD 40 and 80, the Romans laid something like 6,500 miles of highway.

United States

Atlanta 75.85
Interstate 75/85 in Atlanta, Georgia, is a typical urban freeway in United States.

In the United States, "highway" is a general term for denoting a public way, including the entire area within the right-of-way, and includes many forms:

  1. a high-speed, limited-access road like expressways, two-lane expressway, freeways, and large toll highways.
  2. an important road that connects cities and large towns.
  3. any road or street, or a travel way of any kind, including pedestrian ways, trails, and navigable waterways, to which the public has a perpetual right of use.

Note that the phrase "right-of-way" is used differently in the United States than it is in the United Kingdom and certain other places. In the U.S. a highway or road "right-of-way" means the land on which the pavement rests, plus the shoulders beside the pavements, plus any median strip, plus any other adjacent piece of land that is designated for the purposes of the highway or road. In other words, the "right-of-way" is the strip of land for the highway or road, and a sign that says, "No Parking on Right-of-Way" means that drivers may not park on the pavement or on the land adjacent to it.

Many paved highways for vehicles are part of the official National Highway System of the U.S.. Paved highways in the "U.S. Highway" system (for example, U.S. Highway 53) can vary from two lanes wide (one lane each direction), shoulderless, roads with no access control, to multi-lane high-speed controlled-access highway, such as the Interstate Highways. These roads are usually distinguished by being important, but not always the primary, routes that connect populated areas. (Sometimes, the primary route is a State Highway.) Since their inception many decades ago, the construction of "U.S. Highways", and their major improvements, have been paid for 50% with Federal funds, especially from motor fuel taxes, and 50% with State funds from whatever tax resources that the state has. Thus, the system of "U.S. Highways" has always been an equal partnership between the Federal Government and the State governments. This was a plan that changed dramatically with the advent of the Interstate Highway system beginning in the 1950s, but do not forget that the system of "U.S. Highways" continued to be upgraded under the 50%-50% funding. Highways continue to be widened, old bridges continue to be replaces with newer and better ones, and so forth.

The term "Highways" in the U.S. even includes major paved roads that serve purposes similar to those of the U.S. Highways or Interstate Highways, but which are completely designed, paid for, and maintained by state or local governments. An example of this is Tennessee Highway 840, which is a long, partially completed "urban bypass" of Nashville, TN that is a multi-lane, controlled-access highway entirely designed and paid for by Tennessee. Much of the traffic on it will eventually come from Interstate 40, completely avoid the big city, and then return to Interstate 40. Incidentally, Tennessee-840 also has connections with Interstate 24 and Interstate 65, where both of the freeway interchanges are already finished, as well as the eastern interchange with Interstate 40.

When the Act of Congress that authorized the Interstate Highway System was passed and then signed by President Eisenhower, it was already clear that the Interstate Highways would be far more expensive, mile-for-mile, than the U.S. Highways had been. Because of their great cost, Congress decided to set the standard for Federal funding for the Interstate System at 90%, leaving 10% for the States to pay for.

Another monetary difference came from the fact that the Interstate Highways were to be designed to be high-speed and safe expressways. This meant that they needed to have much wider open strips of land along their sides, because this created safety zones on each side of the highways so that vehicles that were in accidents or simply lost control would have somewhere to go, to slow down gradually, and not crash into trees, boulders, light poles, buildings, parked vehicles, fire hydrants, and other kinds of obstacles. Roadway interchanges for Interstate Highways were also to be very large (and over the decades, they became a lot larger than anyone had anticipated in the 1950s). With so much land being taken away for the highways, the only way to justify it and to make it politically palatable was for the Federal and State governments to outright purchase all of the land. There could be no question of just having an easement for the highway and its right-of-way. All of the land within the right-of-way would be permanently owned by the governments, until such time that they decided to get rid of the highway and sell the land.

In some places, "highway" is a synonym for "road" or "street", and in some cases, the word "highway" is simply used in cases of carelessness and laziness on the part of the speaker, who believes that "street", "road", and "highway" are all synonymous and uses them accordingly. On the other hand, in another example, the California Motor Vehicle Code § 360 states: "'Highway' is a way or place of whatever nature, publicly maintained and open to the use of the public for purposes of vehicular travel. Highway includes street." The California Supreme Court has held that "the definition of 'highway' in the Vehicle Code is used for special purposes of that act," and that canals of the town of Venice, California, are "highways" also entitled to be maintained with state highway funds.

The Federal and State governments are trying to improve their national highway systems by repaving highways, widening highways, replacing bridges, and reconstructing some interchanges. Many cloverleaf interchanges are being converted to parclo interchanges. Busy Diamond interchanges are also being converted to SPUIs (single-point-urban interchange) or to parclos to reduce interchange congestion.

Arguably, the most famous United States highway is U.S. Route 66. It is immortalized in the song (Get Your Kicks On) Route 66, and by the legendary TV series Route 66. Other famous highways in songs include Highway 61 (Bob Dylan, 1965), Carefree Highway in Arizona (Gordon Lightfoot, 1974), Colorado Boulevard in Pasadena, California (Jan & Dean, also Beach Boys, 1964), the song Ventura Highway, named for a highway in Southern California ("America", 1972), and Blues Highway in Mississippi (Fred McDowell, 1959).


Yemen has one of the oldest highway routes in the region. The first highway route was between Aden and Hadromout, with a two lane highway. Currently, Yemen has 71,300 kilometers of roads, of which only 6,200 kilometers are paved.


Zimbabwe has one of the better road networks in Africa that had been poorly maintained until recently. There has been an introduction of toll gates and the dualization of most of the major roads.

Bleeding (roads)

Bleeding or flushing is shiny, black surface film of asphalt on the road surface caused by upward movement of asphalt in the pavement surface. Common causes of bleeding are too much asphalt in asphalt concrete, hot weather, low space air void content and quality of asphalt.Bleeding is a safety concern since it results in a very smooth surface, without the texture required to prevent hydroplaning.

Bowtie (road)

The bowtie is a type of road intersection which replaces left turns (in jurisdictions that drive on the right) or right turns (in jurisdictions that drive on the left), with roundabouts on the cross street. It is an alternative to the Michigan left intersection.

Climbing lane

Climbing lanes or crawler lanes are a roadway lane design. They allow slower travel for large vehicles, such as large trucks or semi-trailer trucks, ascending a steep grade. Since climbing uphill is difficult for these vehicles, they can travel in the climbing lane without slowing traffic.

Collector road

A collector road or distributor road is a low-to-moderate-capacity road which serves to move traffic from local streets to arterial roads. Unlike arterials, collector roads are designed to provide access to residential properties. Rarely, jurisdictions differentiate major and minor collector roads, the former being generally wider and busier.

Concrete step barrier

A concrete step barrier is a safety barrier used on the central reservation of motorways and dual carriageways as an alternative to the standard steel crash barrier.


Glassphalt (also spelled "glasphalt") is a variety of asphalt that uses crushed glass. It has been used as an alternative to conventional bituminous asphalt pavement since the early 1970s. Glassphalt must be properly mixed and placed if it is to meet roadway pavement standards, requiring some modifications to generally accepted asphalt procedures.

Generally, there is about 10%-20% glass by weight in glassphalt.


A highway is any public or private road or other public way on land. It is used for major roads, but also includes other public roads and public tracks: It is not an equivalent term to controlled-access highway, or a translation for autobahn, autoroute, etc.

According to Merriam Webster, the use of the term predates 12th century. According to Etymonline, "high" is in the sense of "main".

In North American and Australian English, major roads such as controlled-access highways or arterial roads are often state highways (Canada: provincial highways). Other roads may be designated "county highways" in the US and Ontario. These classifications refer to the level of government (state, provincial, county) that maintains the roadway.

In British English, "highway" is primarily a legal term. Everyday use normally implies roads, while the legal use covers any route or path with a public right of access, including footpaths etc.

The term has led to several related derived terms, including highway system, highway code, highway patrol and highwayman.

Hook turn

A hook turn (also known as a perimeter-style turn in Canada) is a road cycling maneuver and traffic-control mechanism in which vehicles that would normally turn from the closest lane of an intersection instead turn from the farthest lane, across all other lanes of traffic.

Hook turns are commonly used by cyclists as a safer alternative to merging with motor vehicles, or having to cross multiple lanes of traffic to reach a turning lane.

The legal use of hook turns by motor vehicles is relatively rare, but has been implemented in some jurisdictions (notably Melbourne, Australia) to keep the center of a road free from congestion for use by trams or other services.

Link road

A link road is a transport infrastructure road that links two conurbations or other major road transport facilities, often added because of increasing road traffic. They can be controversial, especially if they threaten to destroy natural habitat and greenfield land.

The term is used in the United Kingdom, Australia, and the United States state of Nebraska.

An example of a link road is Marston Ferry Road in Oxford, England. It was built in the late 20th century link North Oxford with Marston, Oxford to the east.

Offset T-intersection

An offset T-intersection is an at-grade road intersection where a conventional four leg intersection is split into two three-leg T-intersections to reduce the number of conflicts and improve traffic flow. Building the offset T-intersections as continuous green T-intersections (also called seagull intersection), there is a single stop on the arterial road, only. A higher volume of through traffic on the cross road, or on unsignalized intersections, a rebuild to a conventional four-leg intersection may be adequate, also when the offset is a few feet only like staggered junctions causing slower traffic for a longer time on the arterial road.Seen as a spur route or access road, offset T-intersections can be seen as an A2 or B2 type partial cloverleaf interchange with no arterial road.


An overpass (called an overbridge or flyover in the United Kingdom and some other Commonwealth countries) is a bridge, road, railway or similar structure that crosses over another road or railway. An overpass and underpass together form a grade separation. Stack interchanges are made up of many overpasses.

Plank road

A plank road is a road composed of wooden planks or puncheon logs. Plank roads were commonly found in the Canadian province of Ontario as well as the Northeast and Midwest of the United States in the first half of the 19th century. They were often built by turnpike companies.

Primitive road

A primitive road is a minor road system, used for travel or transportation that is generally not maintained or paved.

Side road

A side road is a minor highway typically leading off a main road. A side road may be so minor as to be uncategorized with a road number.

In an urban area, a side road may be a narrow street leading off a more major street, especially in a residential area.


Tarmacadam is a road surfacing material made by combining macadam surfaces, tar, and sand, patented by Welsh inventor Edgar Purnell Hooley in 1902. The terms "tarmacadam" and tarmac are also used for a variety of other materials, including tar-grouted macadam, bituminous surface treatments, and modern asphalt concrete. The term is also often used to describe airport aprons (also referred to as "ramps"), taxiways, and runways regardless of the surface.

Traffic island

A traffic island is a solid or painted object in a road that channels traffic. It can also be a narrow strip of island between roads that intersect at an acute angle. If the island uses road markings only, without raised kerbs or other physical obstructions, it is called a painted island or (especially in the UK) ghost island. Traffic islands can be used to reduce the speed of cars driving through, or to provide a central refuge to pedestrians crossing the road.

When traffic islands are longer, they are instead called traffic medians, a strip in the middle of a road, serving the divider function over a much longer distance.When making left turns, drivers will often drive over painted islands even though it is technically illegal. Some traffic islands may serve as refuge islands for pedestrians. Traffic islands are often used at partially blind intersections on back-streets to prevent cars from cutting a corner with potentially dangerous results, or to prevent some movements totally, for traffic safety or traffic calming reasons.In certain areas of the United Kingdom, particularly in The Midlands, the term island is often used as a synonym for roundabout.

Types of road

A road is a thoroughfare, route, or way on land between two places that has been surfaced or otherwise improved to allow travel by foot or some form of conveyance, including a motor vehicle, cart, bicycle, or horse. Roads have been adapted to a large range of structures and types in order to achieve a common goal of transportation under a large and wide range of conditions. The specific purpose, mode of transport, and location of a road determine the characteristics it must have in order to maximize its usefulness. Following is one classification scheme.
