Concurrency (road)

A concurrency in a road network is an instance of one physical roadway bearing two or more different highway, motorway, or other route numbers.[1] When two freeways share the same right-of-way, it is sometimes called a common section or commons.[2] Other terminology for a concurrency includes overlap,[3] coincidence,[4] duplex (two concurrent routes), triplex (three concurrent routes), multiplex (any number of concurrent routes),[5] dual routing or triple routing.[6][7]

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.

Greensboro road signs
An extreme example: I-40, Business I-85, US 29, US 70, US 220, and US 421 ran concurrently in Greensboro, North Carolina. US 220 and US 421 were rerouted from this concurrency in 2008


Most concurrencies are simply a combination of two route numbers on the same physical roadway. This is often practically advantageous as well as economically advantageous; it may be better for two route numbers to be combined into one along rivers or through mountain valleys. Some countries allow for concurrencies to occur, however, others specifically do not allow it to happen. In those nations which do permit concurrencies, it can become very common. In these countries, there are a variety of concurrences which can occur.

An example of this is the concurrency of Interstate 70 (I-70) and I-76 on the Pennsylvania Turnpike in western Pennsylvania. I-70 merges with the Pennsylvania Turnpike so the route number can ultimately continue east into Maryland; instead of having a second physical highway built to carry the route, it is combined with the Pennsylvania Turnpike and the I-76 designation.[8] A triple Interstate concurrency is found in Wisconsin along the five-mile (8.0 km) section of I-41, I-43, and I-894 in Milwaukee, Wisconsin.[9] The concurrency of I-41 and I-43 on this roadway is an example of a wrong-way concurrency.

The longest Interstate highway concurrency is I-80 and I-90 for 265 miles (426 km) across Indiana and Ohio.[10]

There are examples of eight-way concurrencies: I-465 around Indianapolis and Georgia State Route 10 Loop around downtown Athens, Georgia. Portions of the 53-mile (85 km) I-465 overlap with I-74, US Highway 31 (US 31), US 36, US 40, US 52, US 421, State Road 37 (SR 37) and SR 67—a total of eight other routes. Seven of the eight other designations overlap between exits 46 and 47 to create an eight-way concurrency.[11]

Regional examples

QEW and Hwy 403 Concurrency
The QEW concurrent with Highway 403 in Ontario

In the United States, concurrencies are simply marked by placing signs for both routes on the same or adjacent posts. The federal Manual on Uniform Traffic Control Devices prescribes that when mounting these adjacent signs together that the numbers will be arranged vertically or horizontally in order of precedence. The order to be used is Interstate Highways, U.S. Highways, state highways, and finally county roads, and within each class by increasing numerical value.[12]

Several states do not officially have any concurrencies, instead officially ending routes on each side of one.[a] There are several circumstances where unusual concurrencies exist along state borders. One example occurs along the OklahomaArkansas state line. At the northern end of this border Oklahoma State Highway 20 runs concurrently with Arkansas Highway 43 and the two highways run north–south along the boundary.[14]

Concurrencies are also found in Canada. British Columbia Highway 5 continues east for 12 kilometres (7.5 mi) concurrently with Highway 1 and Highway 97, through Kamloops. This stretch of road, which carries Highway 97 south and Highway 5 north on the same lanes (and vice versa), is the only wrong-way concurrency in British Columbia.

In Ontario, the Queen Elizabeth Way and Highway 403 run concurrently between Burlington and Oakville, forming the province's only concurrency between two 400-series highways.[15] The concurrency was not in the original plan which intended for both the QEW and Highway 403 to run parallel to each other, as the Hamilton–Brantford and Mississauga sections of Highway 403 were initially planned to be linked up along the corridor now occupied by Highway 407.Later it was planned for the Mississauga section of Highway 403 would be renumbered as Highway 410 but this never came to pass.[16] Consequently, Highway 403 was signed concurrently along the Queen Elizabeth Way in 2002, remedying the discontinuity to avoid confusing drivers that wanted to travel between the two segments without using the toll Highway 407. Nonetheless, many surface street signs referring to that section of freeway with the QEW/Highway 403 concurrency still only use the highway's original designation of QEW, although the MTO has updated route markers on the QEW to reflect the concurrency.[17]

In the United Kingdom, routes do not run concurrently with others. Where this would normally occur, the roadway takes the number of only one of the routes (usually, but not always, the most important route), while the other routes are considered to have a gap and are signed in brackets (the equivalent of "to" signs in North America). An example is the meeting of the M60 and the M62 northwest of Manchester: the motorways coincide for the seven miles (11 km) between junctions 12 and 18 but the motorway between those points is only designated as the M60. European route numbers as designated by UNECE may have concurrencies (for instance E15 and E30 around Greater London), but since the E-route numbers are unsigned and unused in the UK, the existence of these concurrencies is purely theoretical.

In Sweden and Denmark, the most important highways use only the European route numbers that have cardinal directions. In Sweden the E6 and E20 run concurrently for 280 kilometres (170 mi). In Denmark the E47 and E55 run concurrently for 157 kilometres (98 mi). There are more shorter concurrencies. There are two stretches in Sweden and Denmark where three European routes run concurrently; these are E6, E20 and E22 in Sweden, and E20, E47, and E55 in Denmark. Along all these concurrencies, all route numbers are posted with signs.[18]

In the Czech Republic, the European route numbers are only additional, and they are always concurrent with the state route numbering, usually highways or first-class roads. In the state numbering system, concurrences exist only in first-class and second-class roads; third class roads do not have them. The local term for such concurrences is peáž (somehow derived from the French word péage). In the road register, one of the roads is considered the main ("source") road and the others as the péaging (guest) roads. The official road map enables a maximum of five concurrent routes of the intrastate numbering system.[19] Cycling routes and hiking routes are often concurrent.

The Middle East

In Israel, two freeways, the Trans-Israel Highway (Highway 6), and Highway 1 run concurrently just east of Ben Shemen Interchange. The concurrency is officially designated "Daniel Interchange", providing half of the possible interchange directions. It is a one-mile (1.6 km) segment consisting of eight lanes providing high-speed access between the two highways. Access from Highway 1 west to Highway 6 south and Highway 6 north to Highway 1 east is provided via Route 431, while access between Highway 1 east to Highway 6 north and Highway 6 south to Highway 1 west are provided at Ben Shemen Interchange. The other movements are provided through the concurrency.[20]

Wrong-way concurrencies

This westbound highway in southwestern Virginia simultaneously carries I-77 and I-81 in opposite directions. The wrong-way concurrency is also reflected in US 52 and US 11, which are concurrent with I-77 and I-81, respectively.

Since highways in the United States and Canada are usually signed with assigned cardinal directions based on their primary orientation, it is possible for a stretch of roadway shared between two highways to be signed with conflicting, even opposite, cardinal directions in a wrong-way concurrency. For example, near Wytheville, Virginia, there is a concurrency between I-77 (which runs primarily north–south, as it is signed) and Interstate 81 (which runs primarily northeast–southwest, but is also signed north–south). Because of the way they intersect, the section of Interstate where they overlap has the two roads signed for opposite directions, leading to the town's nickname of "Which-Way-Ville".[21] One might simultaneously be on I-77 northbound and I-81 southbound, while actually traveling due westbound.[22] An unusual example of a three-directional concurrency occurs southeast of Rhinelander, Wisconsin, where US 8 westbound (the actual compass direction) converges with southbound Wisconsin Highway 17 and northbound Wisconsin Highway 47.

Effect on exit numbers

Often when two routes with exit numbers overlap, one of the routes has its exit numbers dominate over the other and can sometimes result in having two exits of the same number, albeit far from each other along the same highway (although in one case the number 96 is only 6 miles [9.7 km] apart). An example of this is from the concurrency of I-94 and US 127 near Jackson, Michigan. The concurrent section of freeway has an exit with M-106, which is numbered exit 139 using I-94's mileage-based numbers. US 127 also has another exit 139 with the southern end of the US 127 business loop in Mount Pleasant, Michigan. (US 127's mile markers in Michigan reflect the cumulative distance north of the Ohio state line; the numbers resume north of the I-94 overlap and reflect the distance accumulated on that concurrency.)[23]

However, there are also instances where the dominant exit number range is far more than the secondary route's highest exit number, for example the concurrency of I-75 and I-85 in Atlanta, Georgia—where I-75 is dominant—the exit numbers range from 242 to 251 while I-85's highest independent mile marker in Georgia is 179.[24]

Consolidation plans

US 1/9 concurrency signed on one shield

Some brief concurrencies in the past have been eliminated by reassigning the designations along the roadways. This can involve scaling back the terminus of one designation to the end of a concurrent section. At the same time, there could be an extension of another highway designation that is used to replace the newly shortened designation with another one.

Between states, US 27 in Michigan previously ran concurrently with I-69 from the Michigan–Indiana state line to the Lansing, Michigan, area. From there it turned northwards to its terminus at Grayling. In 1999, the Michigan and Indiana departments of transportation petitioned the American Association of State Highway and Transportation Officials for permission to truncate US 27 at Fort Wayne, Indiana.[25] In 2002, Michigan removed the US 27 designation from I-69 and extended the US 127 designation from Lansing to Grayling.[26] MDOT's stated reason for the modification was to "reduce confusion along the US 27/US 127 corridor".[27] After US 27's signage was removed, the highway north of the Lansing area was renumbered US 127, and the US 27 designation was removed from I-69.[27]

Some consolidation schemes involve the use of incorporating two single-digit numbers onto one marker, as along the US 1/9 concurrency in northern New Jersey.[28] In the mid-20th century, California had numerous concurrencies, but the California Legislature removed most of them in a comprehensive reform of highway numbering in 1964.[29]

K-140 (Kansas highway)

K-140 is a state highway in Ellsworth and Saline Counties in the U.S. state of Kansas. The highway travels 33.224 miles (53.469 km) through mostly rural land between the cities of Ellsworth and Salina. In addition to connecting Ellsworth and Salina, K-140 travels through the communities of Carneiro, Brookville, and Bavaria. The highway has junctions with Kansas state highways K-14, K-156, K-111, and K-141, as well as Interstate 135. The route was originally established as U.S. Route 40 and was redesignated K-140 after US-40 was made concurrent with Interstate 70. K-140 is not a part of the United States National Highway System, and the entire route is paved with composite pavement. The western part of the highway is less traveled than the eastern part, with annual average daily traffic between 590 and 940 west of Brookville and between 700 and 1200 east of Brookville.

K-244 (Kansas highway)

K-244 is a state highway in the U.S. state of Kansas that is just under four miles (6.4 km) in length. It is east–west spur route that serves Milford Lake in north-central Kansas. It was designated in 1964 as a connector between the lake and the state highway system.

Maine State Route 104

State Route 104 (SR 104) is a 34.9-mile-long (56.2 km) state highway located in Kennebec and Somerset counties in central Maine. Its southern terminus is at SR 8, SR 11 and SR 27 in Augusta. Its northern terminus is at U.S. Route 2 (US 2), US 201 and US 201A in Skowhegan.

Maine State Route 154

State Route 154 (SR 154) is part of Maine's system of numbered state highways, located in Somerset and Piscataquis counties. It runs from Brighton to Ripley, and it is 20.2 miles (32.5 km) long.

Manitoba Highway 12

Provincial Trunk Highway 12 (PTH 12) is a provincial primary highway located in the Canadian province of Manitoba. It runs from the U.S. border (where it meets with Minnesota State Highway 313) to a dead end in Grand Beach. PTH 12 forms the Manitoba section of MOM's Way, a route from Thunder Bay to Winnipeg. Except for a 22 kilometre stretch of four lanes between Steinbach and PTH 1, PTH 12 is a two-lane highway.

Minnesota State Highway 5

Minnesota State Highway 5 (MN 5) is a highway in Minnesota, which runs from its intersection with MN 19 and MN 22 in Gaylord and continues east and northeast to its eastern terminus at its intersection with MN 120 in Maplewood. The route passes through downtown Saint Paul.

Highway 5 is 74 miles (119 km) in length.

Ontario Highway 7

King's Highway 7, commonly referred to as Highway 7 and historically as the Northern Highway, is a provincially maintained highway in the Canadian province of Ontario. At its peak, Highway 7 measured 716 km (445 mi) in length, stretching from Highway 40 east of Sarnia in Southwestern Ontario to Highway 17 west of Ottawa in Eastern Ontario. However, due in part to the construction of Highways 402 and 407, the province transferred the sections of Highway 7 west of London and through the Greater Toronto Area to county and regional jurisdiction. The highway is now 535.7 km (332.9 mi) long; the western segment begins at Highway 4 north of London and extends 154.1 km (95.8 mi) to Georgetown, while the eastern segment begins at Donald Cousens Parkway in Markham and extends 381.6 km (237.1 mi) to Highway 417 in Ottawa.

Highway 7 was first designated in 1920 between Sarnia and Guelph and extended to Brampton the following year. Between 1927 and 1932, the highway was more than doubled in length as it was gradually extended eastward to Perth, where Highway 15 continued to Ottawa. In the early 1960s, that section of Highway 15 was renumbered as Highway 7. In that same decade, the Conestoga Parkway and Peterborough Bypass were constructed. During the 1970s and 1980s, many sections of Highway 7 were widened from the initial two lane cross-section to four or six lanes. Within York Region, the route was upgraded to a limited-access expressway in preparation for the construction of Highway 407.

Soon thereafter, that new tollway would act as justification for transferring the section of Highway 7 through the Greater Toronto Area (GTA) to regional governments. In the west, the construction of Highway 402 between Sarnia and London provided an uninterrupted alternative to Highway 7, resulting in the transfer of the section west of Highway 4. A third transfer took place in Peterborough, briefly separating the route into three discontinuous segments, but has since been rectified by renumbering a section of Highway 7A. From 2007 to 2012, the section of Highway 7 between Carleton Place and Ottawa has been widened to a divided freeway. In addition, work is underway to extend the Conestoga Parkway to New Hamburg as well as to build a new freeway between Kitchener and Guelph.

Tennessee State Route 22

State Route 22 (SR 22) is a 172.8-mile long (278.1 km) south-to-north state highway in the western part of the U.S. state of Tennessee. It begins at the Mississippi state line in McNairy County, where the roadway continues as Mississippi Highway 2. It ends at the Kentucky state line in Lake County, when it crosses into the Kentucky Bend, a detached portion of Fulton County, Kentucky.

The monument for the 1862 Battle of Island Number Ten in the American Civil War is located on SR 22, approximately 3 miles (4.8 km) north of Tiptonville.

Turner Diagonal

The Turner Diagonal (map) is a short freeway in Kansas City, Kansas. It runs from Kansas Avenue northwest to State Avenue. It does not have a single numbered designation, though the entire route was formerly signed as US 40 west of I-70, K-132 east of I-70 and is currently signed as K-32 from Kansas Avenue to its first interchange.

It is named "Turner Diagonal" because it runs diagonally and because it runs into and out of the Turner neighborhood in Kansas City. It provides a convenient shortcut to I-635, bypassing the stoplights on State Avenue and Parallel Parkway. The speed limit is 55 miles per hour (89 km/h) for the entire length of the freeway. The freeway was formerly known as K-132.

U.S. Route 70 in New Mexico

U.S. Route 70 (US 70) is a part of the U.S. Highway System that travels from Globe, Arizona, east to Atlantic, North Carolina. In the U.S. state of New Mexico, US 70 extends from the Arizona state line south of Virden and ends at the Texas state line in Texico.

U.S. Route 80 in Georgia

U.S. Route 80 (US 80) is a 296-mile-long (476 km) U.S. Highway in the U.S. state of Georgia. It travels west-to-east from the Alabama state line in Columbus across the central portion of the state through cities such as Macon, Dublin, Statesboro, and Savannah to connect to its eastern terminus at an intersection with Tybrisa Street and Inlet Avenue in Tybee Island, near the Atlantic Ocean. Here, the roadway continues as Butler Avenue.

In Georgia, all U.S. Highways have at least one state highway that travel concurrently along its route. The main ones that US 80 use are SR 22 from the Alabama state line to Macon; SR 19 from Macon to a point southeast of Montrose; and SR 26 from that point to Tybee Island.
