Route number

A route (or road) number is an identifying numeric (or alphanumeric) designation assigned by a highway authority to a particular stretch of roadway to distinguish it from other routes and, in many cases, also to indicate its classification (e.g. motorway, primary route, regional road, etc.), general geographical location (in zonal numbering systems) and/or orientation (north-south v. east-west). The numbers chosen may be used solely for internal administrative purposes; however, in most cases they are also displayed on roadside signage and indicated on maps.

United Kingdom

Regular roads

In the United Kingdom, road numbers consist of a number up to 4 digits, prefixed with the letters A, B, C or D, but only A and B classifications are signed as being such, whereas C and D classifications are used for internal use by local authorities and government,[1] and then numbered according to the zone in which it is located. For example, the historical main road from London to Edinburgh is called the A1, the "A" in Britain indicates a first class route, classified as more important than "B" roads. The A2, A3, A4, and A5 also radiate out from London (in clockwise order) to points around the coast. All classified roads starting in the zone between the A1 and the A2 begin with the figure 1 (A137, B1412, etc). Scotland is similarly divided into zones by the A7, A8 and A9 which radiate out from Edinburgh.


Motorways are classified as "special roads", and consequently are numbered differently, but in a similar manner. Motorways are either M-class or A(M) class. M-class motorways are labelled in the form Mx, as a higher grade of motorway, and A(M) roads are labelled in the form Ax(M), as upgraded A roads designations, where x is the designation of the road, dependent on the zone. For example, the M25 is the London Orbital Motorway, and the A1(M) is the upgraded A1 dual carriageway[2].

A similar clock-face zonal system is used in many other European countries (for example, Spain and Belgium).

In the United States, numbered highways belong to one of three to four systems of numbered routes, depending on the state. There are two national-level route numbering systems, the older United States Numbered Highway System laid out in 1920s, and the newer Interstate Highway System started in the 1950s. Additionally, every state in the U.S. maintains its own set of numbered state highways. Some states have other systems as well, either a system of numbered county highways or secondary state highways. A few cities also have numbered city highways; for example, the city of Charlotte, North Carolina, maintains Charlotte Route 4.

The U.S. Highway System, indicated by a white shield with black numbers, is based on a numbering grid, with odd routes running generally north–south and even routes running east–west. Primary routes have a one- or two-digit number, and are supplemented by spur routes that add a hundreds digit to their parent route. Routes increase from east-to-west and north-to-south, such that U.S. Route 1 follows the Atlantic Seaboard fall line, while U.S. Route 101 does the same at the Pacific Ocean Coast. Likewise U.S. Route 2 runs near the Canadian border, while U.S. Route 98 follows the Gulf Coast. Major cross-country routes end in either a "1" or a "0". For example, U.S. Route 20 is a route that runs over 3,000 miles (4,800 km) from Boston, Massachusetts, to Newport, Oregon, while U.S. Route 41 spans the country from Miami, Florida, to the Upper Peninsula of Michigan. Routes like U.S. Route 141 and U.S. Route 441 branch off U.S. Route 41. The now defunct U.S. Route 66, known as the "Mother Road", was a cultural touchstone that inspired literature, songs, and other media.

The Interstate Highway System, indicated by a red and blue shield with white numbers, is a system of entirely freeways (unlike the U.S. Highway System, which is mostly undivided surface roads). The Interstate System is also based on a grid, with east–west routes bearing even numbers and north–south routes bearing odd numbers. In order to prevent confusion with the earlier U.S. Highway System, however, the Interstates are numbered in the opposite direction, such that the lowest routes numbers are in the south and west, and the highest numbers in the north and east. Major routes end in either a "0" or a "5"; for example Interstate 10 spans the country from Jacksonville, Florida, to Santa Monica, California, while Interstate 35 goes from the Mexican border to the Great Lakes. Like with U.S. Highways, subsidiary routes are numbered by adding a hundreds digit to the parent route. Because of the large number of these routes, three-digit numbers may be repeated within the system, but unique to each state. Additionally, the parity of the hundreds digit tells the nature of the spur route: odd hundreds digits like Interstate 393 only connect to the system at one end (forming "spurs"), while an even hundreds digit like Interstate 440 indicates that the highway connects to another Interstate at both ends (forming loops).

The numbering system for state highways varies widely from state to state. Each state decides how to number its own routes. Some maintain systems similar to the national road systems, based on a grid. Others number highways regionally, with similar numbers occurring in the same area of the state. Still others have no discernible system, with no connection between a route's location and its number.

In addition to numbers, route numbers also use suffixed letters and banners appended to the tops of signs to indicate alternate routes to the main highway. For example, U.S. Route 1A is the name given to many highways which are either older alignments of U.S. Route 1 or provide an alternate route either around or through a city along U.S. Route 1's route. Banners are sometimes used to indicate alternate routes. Words like "Alternate", "Business", or "Bypass" can be added to a sign to indicate such a situation.


The Trans-Canada Highway system is made up of federally maintained highways, and is the only system that uses route numbering that spans multiple provinces. The provincial highways are assigned numbers by their respective provinces.


All provincial highways are 'Primary Highways'. They are divided into two series', and sub-series'.

  • 1-216 Series — core highway network
    • Hwy 1-100 — intercity
    • Hwy 201, 216 — orbital routes
  • 500-986 Series — local highways
    • Hwy 500-699 — west-east routes
    • Hwy 700-899 — south-north routes
    • 900 and X series — potential realignments and extensions

British Columbia

Owing to the mountainous terrain in the province, route numbers are assigned on a mostly ad hoc basis, and vary between west-east and south-north routes. They currently span from 1-118, except for Hwy 395 which is a counterpart of US 395. Some routes are grouped in numerical patterns (e.g. Highways 9, 11, 13, 15, 17, and 19 are North-South routes with values increasing by increments of two moving West). British Columbia formerly had "400 series" of highways similar to Ontario, but that scheme was dropped in 1973.


Provincial Trunk Highways (PTH) are divided into two series'.

  • PTH 1-199 — primary highways
    • PTH 1-89 — intercity
    • PTH 100, 101, 110 — loop routes
  • PR 200-699 — secondary highways

New Brunswick

Provincial highways are divided into three series'.

  • Route 1-99 — arterial highways
  • Route 100-199 — collector highways
  • Route 200-999 — local highways

Newfoundland and Labrador

Provincial highways are divided into three series'.

  • Main highways have varying numbers

    • Route 402-407, 440-490 — Western Newfoundland
    • Route 500-520 — Labrador
  • Local highways are based on intersecting primary routes and numbered with extension (i.e. 210-1)

Nova Scotia

Provincial highways are divided into five series'.

  • 100-Series — arterial highways
  • Trunk Highways
  • Route 200-399 — collector highways
  • Scenic Routes are unnumbered
  • Local roads are unnumbered


Provincial highways are divided into four classes.

  • Hwy 2-148, 400-427 — King's (primary) highways
    • Hwy 2-148 — intercity
    • 400-series highways (freeways)
  • Hwy 500-699 — secondary highways
  • Hwy 800-813 — tertiary highways

Provincial highways are divided into three series'.

  • Route 1-4 — primary highways
  • Route 4-25 — secondary highways
  • Local highways are numbered by county
    • Route 101-199 — Prince County
    • Route 201-299 — Queens County
    • Route 301-399 — Kings County


Provincial highways are divided into three classes. Odd numbers refer to routes that are generally perpendicular to the Saint Lawrence River. Even numbers refer to routes that are generally parallel to the Saint Lawrence River.

  • Autoroutes - expressways
    • Route numbers for bypasses and spurs take on a prefix (4nn-9nn)
  • 100-series — primary highways
  • Secondary routes
    • 200-series — south of the Saint Lawrence River
    • 300-series — north of the Saint Lawrence River


Provincial highways are divided into three series', and sub-series'.

  • Hwy 1-99 — primary highways
  • Hwy 100-399 — secondary highways which are spurs of primary highways
    • Hwy 102-167 — northern routes
    • Hwy 201-271 — routes to recreational areas
    • Hwy 301-397 — routes to minor communities
  • Hwy 600-799, 900-999 — minor highways
    • Hwy 600-699 — south-north highways
    • Hwy 700-799 — west-east highways
    • Hwy 900-999 — northern or isolated roads

Northwest Territories

There are currently eleven territorial highways in the Northwest Territories. All eleven are named, eight are numbered 1-8, and two are winter roads.


There are a number of roads and highways in Nunavut, none are yet numbered.


There are currently fourteen territorial highways in Yukon. All fourteen are named and numbered 1-11, 14-15, & 37.

People's Republic of China

  • Expressways of China are designated with letter G (for guójiā gāosù 国家高速) or S (for shěng gāosù 省高速) followed by 1, 2, or 4 digits. One digit is used for expressways starting in Beijing (e.g. G5), two digits for long-distance expressways (e.g. G30) and four digits for regional and local expressways (e.g. G9411).
  • G, followed by 3 digits, stand for guódào (国道), or China National Highways.
  • S routes stand for shěngdào (省道), or provincial-level roads.
  • X routes stand for xiàndào (县道), or county-level roads.
  • Y routes stand for xiāngdào (乡道), or township-level roads and C routes stand for cūndào (村道), or village-level roads

Hong Kong

  • Highways or Routes are numbered 1-10; there is no Route 6 (it is a proposed route)
  • Routes are also given names (e.g. Tolo Highway)


Route numbering in Malaysia is fairly simple.


  • All expressways (classified as an expressway by the Malaysian government) has a route number beginning with 'E', followed by a number. (e.g. E1 North–South Expressway Northern Route and New Klang Valley Expressway)
  • All federal roads can have any route number except those stated below. (e.g. Jkr-ft1.png Malaysia Federal Route 1)
  • Industrial roads has a four-digit route number beginning with '3'.
  • Roads build by the Federal Land Development Authority has a four-digit route number starting with '1' or '2'.
  • Institutional facilities roads follow the normal numbering of federal roads.
  • All state roads begins with a letter other than 'E', followed by a number.
Starting Letter State
A Perak
B Selangor
C Pahang
D Kelantan
J Johor
K Kedah
M Melaka
N Negeri Sembilan
P Penang
R Perlis
T Terengganu



  • All major roads in Sabah are federal roads. The route numbers are usually three-digits beginning with '5'.
  • Route 1, 13 and 22 belong to the Pan Borneo Highway.
  • Institutional roads route numbers have three-digits beginning with '6'.
  • State roads normally begins with the letter 'SA', but some roads such as the Sapi-Nangoh Highway starts with the letter 'R'. Papar Spur-Pengalat-Lok Kawi Road and Beluran Road begin with the letter 'A' which is derived from the old route numbering scheme, though both of them are state roads.


  • Federal roads in Sarawak are divided into sections. They have a main route number of '1', referring to the whole stretch of the route (i.e. Jkr-ft1.png Pan Borneo Highway), followed by a dash (-) and the section number. (e.g. Jkr-ft1-13.png Jkr-ft1-14.png Jkr-ft1-15.png Jkr-ft1-16.png Jalan Kuching-Serian)
  • Other roads can have any route number and are also divided into sections.
  • All state roads begin with the letter 'Q' followed by a number. Like federal roads, state roads may also be divided into sections.


  • All federal roads in Labuan have a three-digit number beginning with '7'.


In Australia, road routes are allocated along sections of named roads, often along parts of multiple roads. Unlike many other countries, most highways in Australia tend to be referred to only by their names. State road authorities have separate numbering systems, for internal use only.

State Route

The first route marking system was introduced to Australia in the 1950s. National Routes were assigned to significant interstate routes – the most important road links in the country. National Route 1 was designated to a circular route around the Australian coastline. A state route marking system was designed to supplement the national system, for inter-regional and urban routes within states.[3] When the National Highway system was introduced, National Routes along it became National Highway routes with the same numbers, but with distinctive green and gold route markers. Alphanumeric routes were introduced in Tasmania in 1979,[4] and during the 1990s, planning began for nationally consistent route markings, using the alphanumeric system.[5] Alphanumeric routes have been introduced in most states and territories in Australia, partially or completely replacing the previous systems.[6]

National Routes and Highways

In 1955, the Australian National Route Numbering System was introduced to simplify navigation across Australia. The National Route Numbers are marked by white shields that are present in directional signs, distance signs or trailblazers. The general rule was that odd-numbered highways travel in north-south directions and even-numbered highways in east-west directions, with only a few exceptions. National Route 1 was assigned to a network of highways and roads, which together linked all capital cities and coastal towns circumnavigating the mainland. The National Route system initially linked the centres of towns and cities and terminated at the junction of other national routes, however many bypasses have been constructed since then. National Routes often terminated at the metropolitan city limits rather than the individual city centres.[3]

In 1974, the federal government assumed responsibility for funding the nations most important road links, with the introduction of the National Highway.[7] These highways were marked with distinctive green and gold route marker shields instead of the plain National Route shield. Though the National Highway system has been superseded in subsequent legislation, National Highway route markers are still used on many of the routes. Additionally, National Highways and National Routes have been phased out, or are in the process of being phased out, in all states and territories except Western Australia, in favour of the alphanumeric system.[8][9][10]

State Routes

Important urban and inter-regional routes not covered by the National Highway or National Route systems are marked under the State Route system. They can be recognised by blue shield markers. They were practically adopted in all states by the end of the 1980s, and in some states, some less important National Routes were downgraded to State Routes. Each state has or had its own numbering scheme, but do not duplicate National Route numbers in the same state, or nearby routes in another state.[3] As with the National Routes and National Highways, State Routes are being phased out in most states and territories in favour of alphanumeric routes.[8][9][10][11] However, despite the fact that Victoria has fully adopted alphanumeric routes in regional areas, state route numbers are still used extensively within the city of Melbourne as a part of its Metropolitan Route Numbering Scheme.[12]


AUS Metroad 5
Metroad route marker

In the 1990s in Sydney and Brisbane, urban route numbering system were streamlined under the Metroad scheme. Metroad route numbers were assigned to the key navigational corridors, along ring and radial routes, and marked by distinctive hexagonal shields.[11] Most Metroads have been completely or partially replaced with alphanumeric routes in Brisbane, and they have been fully replaced in Sydney.[11]

Alphanumeric routes

Tasmania introduced an alphanumeric route numbering system in 1979, based on the British system from 1963. The new system aimed to upgrade the signing of destinations, including previously unmarked roads, and to simplify navigation by allowing visitors to follow numbered routes. National Highway 1 was retained as the only route without an alphanumeric designation.[4] In the 1990s Victoria and South Australia also overhauled their systems. While South Australia discarded the National and State Route Numbering Systems, those shield-based schemes were retained in the Melbourne metropolitan area as the Metropolitan Route Numbering Scheme.[12] The route numbers used in the alphanumeric schemes were generally inherited from the original National Route Numbering System, with only a few exceptions, and prefixed with letters denoting their grade. For example, Western Freeway is M8 until Ballarat and continues beyond as A8 Western Highway. They are not used extensively in the Melbourne metropolitan area where the blue-shield metropolitan route system is retained for most routes. The National Highways were retained, but with the route numbers changed to alphanumeric designations.

New South Wales and the Australian Capital Territory[a] introduced the alphanumeric system from early 2013.[8] Before being officially announced, new road signs were fitted with such numbers and then being "coverplated" with the existing route number. However, the new system does not distinguish between the former National Highways and other routes.

Alphanumeric routes have also been introduced for many major highways and urban routes in Queensland, although many other roads retain markers from the National Route, National Highway, State and Metroad numbering systems. According to the New South Wales Roads and Maritime Services, the Northern Territory has similarly begun converting their numbered routes to alphanumeric routes, with a "progressive replacement" scheme that sees alphanumeric route markers introduced only when signs are replaced.[11] There are no plans to introduce an alphanumeric route numbering system in Western Australia.[10]

Prefix letters

In the alphanumeric systems, a letter denoting the route's construction standard and function is prefixed to the route number, creating an alphanumeric route designation. One of four letters may be used:

  • "M" routes are primary traffic routes, called motorways in some states. These are typically dual carriageway, freeway-standard highways, but may also be used for rural roads that are nearly at freeway-standard,[13] or at least are dual carriageways.[12]
  • "A" routes are other primary highways, including urban arterials[13] and interstate or interregional single carriageways.[12][13]
  • "B" routes are less significant routes, either as an alternative to an "A" or "M" route, or linking smaller population centres to larger regional centres, but without being a major through-route in the region.[13] These are the major road links in areas without "A" routes.[12]
  • "C" routes link smaller settlements and towns to the rest of the major road network.[12] They are used for roads without the significance of an "M", "A", or "B" route, but where numbering would assist navigation.[13]



In Germany, the normal route number for the German autobahns consists of the letter A and a number:

  • 1-digit-numbers are the most important autobahns;
  • 2- and 3-digit numbers are for connectors of 1-digit-number-autobahns; and
  • north–south routes have odd numbers, and east–west routes have even numbers.


Bundesstraßen are national highways, their numbers consist of the letter B and a number:

  • 1-digit numbers are more important than 2- or 3-digit numbers;
  • the first ten roads span the entire country, the 2-digit roads were assigned sequentially in clusters connecting the major regions, and the 3-digit roads are usually shorter connector roads.
  • short branches of Bundesstraßen are sometimes signed with the letter "a" (e.g. B 27a); and
  • rerouted Bundesstraßen may be given numbers with an appended "n" (e.g. B 7n).

West Berlin once had its own Bundesstraßen with letters.

State roads

State roads are roads operated by the German federal states. They are called Landesstrasse or Staatsstrasse (in Saxony and Bavaria). They are labeled by an initial L or S and a one- to four-digit individual number (e.g. S2 or L240). The federal states sustain their own numbering systems with individual styles of number shields used.

France still uses Route Nationale numbers from an 1824 revision of 1811 numbers made under Napoleon.

Some countries, such as Brazil, number their national highways by direction. (BR1xx = North/South highways, BR2xx = East/West, BR3xx = 'Diagonal' (i.e. NW/SE or NE/SW)).

Canada Water

Canada Water is an area of the Docklands in south-east London. It is named after a freshwater lake and wildlife refuge. Canada Water tube, Overground and bus station is immediately north of the lake, along with Canada Water Library which overhangs the lake and Deal Porter Square. Surrey Quays Shopping Centre is also adjacent, sitting immediately to the south. The surrounding area, which forms the town centre of Rotherhithe, is now increasingly known as Canada Water, after the transport interchange as much as the lake itself. The area is famous for being the terminus point for the bus route number 1.

Central Coast Highway

The Central Coast Highway is a major road corridor through the Central Coast region of New South Wales, Australia. The route was officially named by the New South Wales state government on 9 August 2006 and aims to provide an easily identifiable route through the Coast for visitors to the region.Under the alpha-numeric route number changes announced by Roads and Maritime Services in September 2012, in mid 2013 the Central Coast Highway was assigned the A49 route designation for its entire length from Kariong to Doyalson. Before that, the highway carried the State Route 83 designation previously held by the Pacific Highway from Kariong to Gosford, where the Pacific Highway recommences.

Concurrency (road)

A concurrency in a road network is an instance of one physical roadway bearing two or more different route numbers. When two roadways share the same right-of-way, it is sometimes called a common section or commons. Other terminology for a concurrency includes overlap, coincidence, duplex (two concurrent routes), triplex (three concurrent routes), multiplex (any number of concurrent routes), dual routing or triple routing.Concurrent numbering can become very common in jurisdictions that allow it. Where multiple routes must pass between a single mountain crossing or over a bridge, or through a major city, it is often economically and practically advantageous for them all to be accommodated on a single physical roadway. In some jurisdictions, however, concurrent numbering is avoided by posting only one route number on highway signs; these routes disappear at the start of the concurrency and reappear when it ends.

Destination sign

A destination sign (North American English) or destination indicator/destination blind (British English) is a sign mounted on the front, side or rear of a public transport vehicle, such as a bus, tram/streetcar or light rail vehicle, that displays the vehicle's route number and destination, or the route's number and name on transit systems using route names. The main such sign, mounted on the front of the vehicle, usually located above (or at the top of) the windshield, is often called the headsign, most likely from the fact that these signs are located on the front, or head, end of the vehicle. Depending on the type of the sign, it might also display intermediate points on the current route, especially if the route is particularly long and its final terminus by itself is not very helpful in determining where the vehicle is going.

Eyre Peninsula

The Eyre Peninsula is a triangular peninsula in South Australia. It is bounded on the east by Spencer Gulf, the west by the Great Australian Bight, and the north by the Gawler Ranges.

It is named after explorer Edward John Eyre who explored parts of the peninsula in 1839-1841. The coastline was first charted by the expeditions of Matthew Flinders in 1801-1802 and French explorer Nicolas Baudin around the same time.

The peninsula's economy is primarily agricultural, with growing aquaculture, mining and tourism sectors. The main townships are Port Lincoln in the south, Whyalla and Port Augusta in the north east, and Ceduna in the northwest.

Highway shield

A highway shield or route marker is a sign denoting the route number of a highway, usually in the form of a symbolic shape with the route number enclosed. As the focus of the sign, the route number is usually the sign's largest element, with other items on the sign rendered in smaller sizes or contrasting colors. Highway shields are used by travellers, commuters, and all levels of government for identifying, navigating, and organising routes within a county, state, province, or country. Simplified highway shields often appear on maps.

ICF Colony

ICF Colony in Chennai is the locality of Integral Coach Factory which produces a large amount of train coaches across India. The area also consists of a bus depot and the ICF Hospital. Route number 47A is the bus service from ICF Colony to Thiruvanmiyur.

International E-road network

The international E-road network is a numbering system for roads in Europe developed by the United Nations Economic Commission for Europe (UNECE). The network is numbered from E 1 up and its roads cross national borders. It also reaches Central Asian countries like Kyrgyzstan, since they are members of the UNECE.

European main international traffic arteries are defined by ECE/TRANS/SC.1/2016/3/Rev.1 which consider three types of roads: motorways, express roads, and ordinary roads.

In most countries, roads carry the European route designation beside national road numbers. Other countries like Belgium, Norway and Sweden have roads with exclusive European route signage (Examples: E 18 and E 6), while at the other end of the scale, British road signs do not show the routes at all. Denmark uses exclusive European routes, but uses also formal names for every motorway (or part of such), which the motorways are referred to, for instance in news and weather forecasts.

Other continents have similar international road networks, e.g., the Pan-American Highway in the Americas, the Trans-African Highway network, and the Asian Highway Network.

Legislative route

In United States, a legislative route (LR) or legislative highway is a highway defined by laws passed in a state legislature. The numbering of such highways may or may not correspond to the numbers familiar to the public as part of the state, U.S. highway, and Interstate highway systems. Legislative routes may be composed of several such roads, and conversely, state, U.S., and Interstate highways may be made up of several legislative routes. Minnesota also had highways defined in an amendment to the Minnesota State Constitution in 1920, and those roads are known as constitutional routes.

List of cycle routes in London

This article provides a list of cycle routes in the Greater London area that have been waymarked with formal route signage.

The routes include Cycle Superhighways, Quietways and the older London Cycle Network Plus, all designated by local government body Transport for London (TfL), and National Cycle Network routes designated by sustainable transport charity Sustrans, and miscellaneous 'Greenways' created by various bodies.

Note: not all these routes are dedicated 'traffic free' cycle tracks: most of them also include ordinary roads shared with motor traffic and footpaths shared with pedestrians.

Major roads in the Wheatbelt region of Western Australia

Highways and main roads in the Wheatbelt region of Western Australia form the basis of a road network, which is primarily used by the mining, agriculture, and tourism industries. Main Roads Western Australia maintains and controls these major roads, with offices based in Northam and Narrogin.

There are six main highways through the Wheatbelt that radiate out from Perth:

Brand Highway (north-west to Geraldton)

Great Northern Highway (north-east to Wyndham)

Great Eastern Highway (east to Kalgoorlie)

Great Southern Highway (east to York, then south to Cranbrook)

Brookton Highway (east-south-east to Brookton)

Albany Highway (south-east to Albany)A network of main roads connects towns within the Wheatbelt to each other, the highways, and neighbouring regions, with local roads providing additional links and access to smaller townsites. Roads are often named after the towns they connect.

Malaysian State Roads system

Malaysian State Roads System (Malay: Sistem Laluan Negeri Malaysia) are the secondary roads in Malaysia. The construction of state roads in Malaysia is funded by Malaysian Public Works Department (JKR) of each state. The standard of the state roads is similar with the federal roads except for the coding system, where the codes for state roads begin with state codes followed by route number, for example Johor State Route J32 is labeled as J32. If a state road crosses the state border, the state code will change, for example route B20 in Salak Tinggi, Selangor will change to N20 after crossing the border of Negeri Sembilan to Nilai.

Numbered highways in the United States

Highways in the United States are split into at least four different types of systems: Interstate Highways, U.S. Highways, state highways, and county highways. Highways are generally organized by a route number or letter. These designations are generally displayed along the route by means of a highway shield. Each system has its own unique shield design that will allow quick identification to which system the route belongs. Below is a list of the different highway shields used throughout the United States.

Roads in Ireland

The island of Ireland, comprising Northern Ireland and the Republic of Ireland, has an extensive network of tens of thousands of kilometres of public roads, usually surfaced. These roads have been developed and modernised over centuries, from trackways suitable only for walkers and horses, to surfaced roads including modern motorways. The major routes were established before Irish independence and consequently take little cognisance of the border other than a change of identification number and street furniture. Northern Ireland has had motorways since 1962, and has a well-developed network of primary, secondary and local routes. The Republic started work on its motorway network in the early 1980s; and historically, the road network there was once somewhat less well developed. However, the Celtic Tiger economic boom and an influx of European Union structural funding, saw national roads and regional roads in the Republic come up to international standard quite quickly. In the mid-1990s, for example, the Republic went from having only a few short sections of motorway to a network of motorways, dual carriageways and other improvements on most major routes as part of a National Development Plan. Road construction in Northern Ireland now tends to proceed at a slower pace than in the Republic, although a number of important bypasses and upgrades to dual carriageway have recently been completed or are about to begin.

Roads in Northern Ireland are classified as either Highways, motorways (shown by the letter M followed by a route number, e.g. M1), A-roads (shown by the letter A followed by a route number, e.g. A6), B-roads (shown by the letter B followed by a route number, e.g. B135) and other roads. There are two types of A-roads: primary and non-primary.

Roads in the Republic are classified as either motorways (shown by the letter M followed by a route number, e.g. M7), national roads (shown by the letter N followed by a route number, e.g. N25), regional roads (shown by the letter R followed by a route number, e.g. R611) and local roads (shown by the letter L followed by a route number, e.g. L4202). There are two types of national roads: national primary routes and national secondary routes.

Distance signposts in Northern Ireland show distances in miles, while all signposts placed in the Republic since the 1990s use kilometres. The Republic's road signs are generally bilingual, using both official languages, Irish and English. However, signs in the Gaeltacht (Irish speaking areas) use only Irish. The Irish language names are written in italic script, the English in capitals. Signs in Northern Ireland are in English only. Warning signs in the Republic have a yellow background and are diamond-shaped, those in Northern Ireland are triangle-shaped and have a white background with a red border.

Speed limits in Northern Ireland are specified in miles per hour. Those in the Republic use kilometres per hour (km/h), a change introduced on 20 January 2005. This involved the provision of 58,000 new metric speed limit signs, replacing and supplementing 35,000 imperial signs.

Special route

In road transportation in the United States, a special route is a road in a numbered highway system that diverts a specific segment of related traffic away from another road. They are featured in many highway systems; most are found in the Interstate Highway System, U.S. highway system, and several state highway systems. Each type of special route possesses generally defined characteristics and has a defined relationship with its parent route. Typically, special routes share a route number with a dominant route, often referred as the "parent" or "mainline", and are given either a descriptor which may be used either before or after the route name, such as Alternate or Business, or a letter suffix that is attached to the route number. For example, an alternate route of U.S. Route 1 may be called "Alternate U.S. Route 1", "U.S. Route 1 Alternate", or "U.S. Route 1A". Occasionally, a special route will have both a descriptor and a suffix, such as U.S. Route 1A Business.

Unsigned highway

An unsigned highway is a highway that has been assigned a route number, but does not bear road markings that would conventionally be used to identify the route with that number. Highways are left unsigned for a variety of reasons, and examples are found throughout the world. Depending on the policy of the agency that maintains the highway, and the reason for not signing the route, the route may instead be signed a different designation from its actual number, with small inventory markers for internal use, or with nothing at all.
