{{Redirect category shell|1=
A '''wrong-way concurrency''' is a [[concurrency (road)|road concurrency]] in which at least two numbered [[highway]] routes are signed in opposite, conflicting directions on the same stretch of physical roadway.
{{R from merge}}

{{R to section}}
Although each route is logically consistent with itself, wrong-way concurrency signage may lead to confusion among motorists.
}}

The road itself is likely to be actually pointed in a third direction. For example, a north-south wrong-way concurrency would typically occur on a stretch of road that physically runs east-west; and [[List of Latin phrases (P–Z)#V|vice versa]].

This oddity is not to be confused with situations where a north-south route shares an east-west route, which is a very common occurrence. Also, there are some cases where a route's posted direction is not the same for the entire route (thus need careful consideration of apparent wrong-way concurrency), with these examples:
* "[[Beltway]]" situation, such as [[Interstate 695 (Maryland)|I-695]] around [[Baltimore, Maryland|Baltimore]] and [[Capital Beltway|I-495]] around [[Washington, DC]].
* [[Interstate 69|I-69]], connecting [[Indianapolis, Indiana|Indianapolis]] and [[Port Huron, MI]]; south of [[Lansing, Michigan]] it is posted as north-south and east of Lansing it is posted as east-west.
* At least part of [[U.S. Route 1|US 1]] in [[Connecticut]] has been posted as east-west, although for the rest of its route (from [[Canada]] to [[Key West, Florida]]) it is posted north-south.

==List of wrong-way concurrencies==
{{examplefarm}}
===United States===
====Alabama====
* [[Interstate 359]] and [[State Route 69 (Alabama)|State Route 69]] are wrong-way concurrent with [[U.S. Route 11]] in [[Tuscaloosa, Alabama|Tuscaloosa]]. Southbound U.S. 11 is co-routed with northbound S.R. 69 between Skyland Boulevard and 15th Street. When U.S. 11 and S.R. 69 junction with I-359 at its interchange with [[Interstate 20]]/[[Interstate 59]], northbound I-359 and S.R. 69 share the wrong-way concurrency with southbound U.S. 11.
* Northbound State Route 69 is co-routed with southbound [[Alabama State Route 5|State Route 5]] through [[Jasper, Alabama|Jasper]] along the former route of [[U.S. Route 78]]. The roadway runs in a general east-west orientation.
* [[U.S. Route 80]] and [[U.S. Route 280]] are briefly wrong-way concurrent at [[Phenix City, Alabama|Phenix City]]
* Northbound [[Alabama State Route 35|State Route 35]] is routed with southbound [[U.S. Route 11]] at [[Fort Payne, Alabama|Fort Payne]]. U.S. 11 is generally a northeast-southwest route, while State Route 35 is generally a northwest-southeast route.
* Southbound [[U.S. Route 29]] and northbound [[Alabama State Route 55|State Route 55]] as they approach downtown [[Andalusia, Alabama|Andalusia]] from the east. The two routes share the same roadway as [[U.S. Route 84]].
* Southbound U.S. 29 is co-routed with northbound [[Alabama State Route 41|State Route 41]] as they approach downtown [[Brewton, Alabama|Brewton]] from the southeast.

====California====
* A section of the [[Eastshore Freeway]] in [[Albany, California|Albany]], [[Berkeley, California|Berkeley]], [[Emeryville, California|Emeryville]], and [[Oakland, California|Oakland]] [[California]] is signed as [[Interstate 80|I-80]] and [[Interstate 580 (California)|I-580]] in opposite directions.

====Georgia====
* In [[Bartow County, Georgia|Bartow County]], [[U.S. Route 41]] and [[U.S. Route 411]] are wrong-way concurrent for a short distance where U.S. Route 411 abruptly changes from a north-south orientation to an east-west orientation (although the signage on the highway is still north-south). A proposed connection between the northern junction of the two routes and [[Interstate 75]] will remove the concurrency if completed.
* In north [[Cobb County, Georgia|Cobb County]], [[Georgia (U.S. state)|Georgia]], a wrong-way concurrency is made up of [[U.S. Route 41]] North and Georgia S.R. 92 South.

====Illinois====
* Near Raymond, IL 48 goes north and IL 127 goes south in a wrong-way concurrency for about 8 miles.
* Illinois 72 runs concurrently with Illinois Route 47 and U.S. Highway 20 by Starks, an unincorporated village approximately 60 miles from Chicago. (This) is a Wrong-way concurrency, where one can be driving both west on Illinois 72 and east on U.S. 20 at the same time. (from the Illinois Route 72 article)
* in [[Harvard, Illinois|Harvard]], US 14 and Illinois 173, for approximately 1 mile.

====Iowa====
* On the southwest side of [[Cedar Rapids, Iowa|Cedar Rapids]], [[U.S. Route 151]] and [[U.S. Route 218]] run in opposite directions while also concurrent with [[U.S. Route 30]].
* [[U.S. Route 65]] and [[Iowa Highway 5]], both north-south highways, are wrong-way concurrent for 3 miles between [[U.S. Route 69]] and [[Carlisle, Iowa|Carlisle]].
* [[U.S. Route 30]] and [[Iowa Highway 37]] are wrong-way concurrent for 3 blocks in [[Dunlap, Iowa|Dunlap]].

====Kansas====
* South of Pittsburg, a north-south stretch of road is wrong-way concurrent with north-south [[U.S. Route 69]], and east-west highways [[U.S. Route 160]] and [[U.S. Route 400]]. If you are going to the north, you are going north on 69, west on 400 and east on 160.

====Massachusetts====
* In 1989, [[U.S. Route 1]] was relocated to follow I-95 and I-93 into Boston. The I-95 portion of this concurrency proceeding east is marked as US 1 North, I-95 South and MA 128 South. Further north, in [[Burlington, Massachusetts|Burlington]], the highway has yet another short wrong-way concurrency. [[U.S. Route 3]] is a [[freeway]] north of Route 128. The originally planned freeway to the south was cancelled in 1970, so US 3 South takes a short jog on Route 128 and I-95 North (travelling east-northeast) to get back to its original alignment.
* In [[Fitchburg, Massachusetts|Fitchburg]], though the signs in this segment do not claim a direction to avoid confusion, [[Route 31 (Massachusetts)|Route 31]] heads north as [[New England Route 12|Route 12]] heads south.

====Nebraska====
* From west of Long Pine to Bassett, southbound [[U.S. Route 183]] and northbound [[Nebraska Highway 7]] are concurrent. This is a segment of highway shared with U.S. Route 20.

In Illinois, US 136 (East-West) joins US 24 (North-South) and Illinois 100 (North-South) from Duncans Mills, to two miles south, in Fulton County.

====New York====
*[[Interstate 890|I-890]] and [[New York State Route 7]] have a wrong-way concurrence between exits 7 and 9A in Rotterdam, south of Schenectady. In this portion of I-890, the highway is oriented North-South.
*[[New York State Route 59]] and [[US Route 202]] have a wrong-way concurrence for 0.05 miles in [[Suffern, New York]].
*[[US Route 20]] and [[New York State Route 146]] have a wrong-way concurrence in Guilderland, west of Albany.

====New Jersey====

* In [[Sussex County]], [[New Jersey State Route 94]] and [[Sussex County Route 517]] feature a wrong-way north-south concurrency that runs right past [[Mountain Creek]] water park/ski resort.

====North Carolina====
[[Image:IMG 661011.jpg|thumb|right|150px|Greensboro's Death Valley]]
* In [[Greensboro, North Carolina|Greensboro]], [[North Carolina]], [[Interstate 40]], [[Interstate 85 Business (North Carolina)|Business 85]], [[U.S. Route 29]], [[U.S. Route 70]], [[U.S. Route 220]], and [[U.S. Route 421]] are all concurrent. US 421 is wrong-way, as can be seen to the right. The 2.5 mile stretch where these routes are concurrent is known as [[Death Valley (North Carolina)|Death Valley]].

====Ohio====
* From Aberdeen to Ripley along the Ohio River, [[U.S. Route 52|US 52]], [[U.S. Route 52|US 62]], and [[U.S. Route 68|US 68]] form a wrong-way concurrency for about 8 miles. US 68 enters Ohio concurrent with US 62 with both being bannered as east-west routes in Kentucky, but with US 68 a north-south route in Ohio. US 68 Northbound and US 62 Eastbound enter from Kentucky over a new bridge west of Aberdeen and join US 52 Westbound until leaving in Ripley. US 52 is also notable for changing directions from north-south to east-west in different states, and also is involved in a wrong-way concurrency in Virginia with US 11, I-77, and I-81. [http://www2.uakron.edu/genchem/images/52-62-68.jpg Sign Assembly near Aberdeen just after US 62/68 EB enter from Kentucky and become US 62 EB and US 68 NB and join US 52 WB]

*The bypass around [[Fremont, Ohio]] carries four routes: [[U.S. Route 6|US 6]], [[U.S. Route 20|US 20]], [[State Route 19 (Ohio)|State Route 19]], and [[State Route 53 (Ohio)|State Route 53]]. For a short distance a wrong-way concurrency occurs in which one can travel east on US 6, east on US 20, north on State Route 53, and south on State Route 19. In the other direction one will be traveling west on US 6, west on US 20, north on State Route 19, and south on State Route 53.

*Near [[Perrysburg, Ohio|Perrysburg]], [[Ohio]], southwest of [[Toledo, Ohio|Toledo]], north-south [[Interstate 75|I-75]] and north-south [[U.S. Route 23]] form a wrong-way concurrency for about one [[mile]] (1.6km) between the I-75/[[Interstate 475 (Ohio)|I-475]] and I-75/[[U.S. Route 20]]/[[U.S. Route 23]] interchanges.

*[[Ohio State Route 7|State Route 7]] and [[Ohio State Route 60|State Route 60]] briefly experience this phenomenon in [[Marietta, Ohio|Marietta]].

*[[U.S. Route 50|US 50]], [[U.S. Route 33|US 33]], and [[Ohio State Route 32|OH-32]] converge at [[Athens, Ohio|Athens]]. One may travel west on US 50 and OH-32 while simultaneously driving east on US 33, or vice-versa.

====Oklahoma====
* In [[Oklahoma City, Oklahoma|Oklahoma City]], [[Oklahoma]], [[State Highway 3 (Oklahoma)|State Highway 3]] is wrong-way concurrent with [[Interstate 44]]. Both roads are signed east-west.
* Between [[Tonkawa, Oklahoma|Tonkawa]] and [[Ponca City, Oklahoma|Ponca City]], north-south routes [[U.S. Route 77|US 77]] and [[U.S. Route 177|US 177]] are concurrent with [[U.S. Route 60|US 60]]. For the 13 miles between the towns, the east-west route is signed both north and south for US 77 and US 177.

====Pennsylvania====
* In [[Pittsburgh]], there is a 5-route concurrency of [[I-279]], [[US Route 22]], [[U.S. Route 30|US Route 30]], [[US Route 19]], and [[U.S. Route 19 Truck (Pittsburgh, Pennsylvania)|US Route 19 Truck]] for a short distance just before the [[Fort Pitt Tunnel]]. Here there are several wrong-way concurrencies, including US 19 Truck North and US 19 Truck South being the same road, US 19 South and US 19 Truck North being the same road, and several other combinations of ramps that include wrong-way concurrencies of US 19 and US 19 Truck.
* In [[Williamsport, Pennsylvania]], a portion of [[US 15]] is a wrong-way concurrency along with [[US 220]]. Both are north-south roads. The stretch of highway runs east to west, and the east-west [[Interstate 180 (Pennsylvania)|I-180]] also shares this stretch of road.
* The infamous section of [[US 30]] in [[Breezewood, Pennsylvania]] that is also part of the main route of [[I-70]] is wrong-way concurrent; eastbound I-70 traffic travels west on US 30 (and the map) through Breezewood, and vice versa. The entire section is unsigned.
* West of [[Philadelphia, Pennsylvania]], a portion of [[U.S. Route 1]] is wrong way concurrent with [[Pennsylvania Route 52]]. (This stretch is about a mile, and is just east of Longwood Gardens.)
* Near [[Carbondale]], there is a wrong way north-south concurrency between [[Pennsylvania Route 171|PA 171]] and [[Pennsylvania Route 670|PA 670]].

====South Carolina====
* Between Gardens Corner, SC and Pocotaligo, SC a short stretch of US Route 21 and US Route 17 are wrong-way concurrent, with US 21 South and US 17 North sharing a stretch of road. This stretch is used by travelers headed to the Beaufort area from I-95.

====Tennessee====
* In [[Chattanooga]], [[U.S. Route 11]] and [[U.S. Route 41]] are wrong-way concurrent for about five miles looping around the base of [[Lookout Mountain]] and a large bend in the [[Tennessee River]] via Cummings Highway and S. Broad Street. Adding to the confusion, construction signage on adjacent [[Interstate 24]] approaching Chattanooga from the west lists truck restrictions on [[U.S. Route 41]] East (even though it is a north-south route). [[U.S. Route 64]] and [[U.S. Route 72]] are concurrent along the same section.
* In [[Pigeon Forge, Tennessee|Pigeon Forge]] and [[Gatlinburg, Tennessee|Gatlinburg]], [[Tennessee]], a 7.3-mile (11.8-km) section of the [[Great Smoky Mountains Parkway]] is a wrong-way concurrency of [[U.S. Route 321]] and [[U.S. Route 441]]. (Further confusing things, [[State Route 71 (Tennessee)|State Route 71]] and [[State Route 73 (Tennessee)|State Route 73]] are also concurrent along that section.)
* Also near the Smoky Mountains, [[U.S. Route 411]] and [[U.S. Route 441]] are wrong-way concurrent between [[Seymour, Tennessee|Seymour]] and [[Sevierville, Tennessee|Sevierville]]. Although the routes are north-south, this segment travels close to due east-west. The similarity of the route numbers further confuses things.
* In the northeastern part of the state, a 2.7-mile (4.3-km) segment of the [[Lee Highway]] between [[Tate Springs, Tennessee|Tate Springs]] and [[Bean Station, Tennessee|Bean Station]] includes a wrong-way north-south concurrency of [[U.S. Route 25E]] and [[U.S. Route 11W]]. This concurrency is especially unusual due to the opposing E (east) and W (west) designations of the two U.S. highways — thus, a motorist heading from Tate Springs to Bean Station (in a generally eastward direction) would be travelling north on 25E and, simultaneously, south on 11W. [http://www.millenniumhwy.net/interestingsigns/tn/index.html (photos)] In addition, [[State Route 1 (Tennessee)|State Route 1]] and [[State Route 32 (Tennessee)|State Route 32]] are concurrent along this stretch.

====Texas====
* The 2.9 miles of road from [[Corley, Texas]] eastward to [[Maud, Texas|Maud]] are signed as northbound [[U.S. Route 67]] and southbound [[State Highway 8 (Texas)|State Highway 8]].
* Traveling from [[Vernon, Texas|Vernon]] to [[Oklaunion, Texas|Oklaunion]] is designated northbound [[U.S. Route 183]] and southbound [[U.S. Route 287]].
* A short stretch west of [[Victoria, Texas]] is signed as northbound [[U.S. Route 59]] and southbound [[U.S. Route 77]].

[[Image:IMG 11601.jpg|thumb|right|150px]]

====Virginia====
* Less famous but no less confusing is the [[Interstate 77|I-77]]/[[Interstate 81|I-81]] wrong-way concurrency in [[Southwest Virginia|southwestern]] [[Virginia]] ''(pictured above)'', which is simultaneously North 81 and South 77. In the [[1980s|80s]] and early [[1990s|90s]], this section was particularly confusing due to poor (almost nonexistent) signage, but this problem was remedied around [[1996]]. Additionally, [[U.S. Route 52]] and [[U.S. Route 11]] are also wrong-way concurrent, making the roadway doubly wrong-way concurrent. Making matters even more confusing for travelers, the exit number for 77 south is 81.
* Upon completion of [[Interstate 73]] in Virginia, Interstate 81 will have its second wrong-way concurrency in the state. Interstate 73, coming north from [[North Carolina]], will run south along I-81 from current [[Interstate 581]] in [[Roanoke, Virginia|Roanoke]] to [[U.S. Route 460]] in [[Christiansburg, Virginia|Christiansburg]], and head north to [[West Virginia]].
* In [[Lynchburg, Virginia|Lynchburg]], [[Virginia]], concurrent north-south [[U.S. Route 29]] and east-west [[U.S. Route 460]] meet with north-south [[U.S. Route 501]]. US 29 and US 501 are wrong-way for approximately 2.5 miles ''(right)''.

====Wisconsin====
* A short stretch of the [[U.S. Route 10]] freeway around [[Waupaca, Wisconsin|Waupaca]], [[Wisconsin]] contains a wrong-way concurrency of north-south [[Highway 22 (Wisconsin)|Highway 22]] and [[Highway 49 (Wisconsin)|Highway 49]], as well as [[Highway 54 (Wisconsin)|Highway 54]]. There is one set of route markers in each direction; traveling west, the highway is marked as US 10 west, WIS 22 south, WIS 49 north and WIS 54 west.

* In the [[Janesville, Wisconsin|Janesville]] area, as a result of a recently constructed bypass around Janesville, eastbound [[Wisconsin Highway 11]] runs with westbound [[Interstate 90]] and northbound [[Interstate 39]] between exits 177 and 175 of I-90.

===Canada===
====British Columbia====
[[Image:wrongway-multiplex.png|right|thumb|A wrong-way concurrency in the interior of [[British Columbia]]; 97 south is 5 north, which is also 1 east]]
* A section of the [[Trans-Canada Highway]] within [[Kamloops, British Columbia|Kamloops]] is signed as [[British Columbia Highway 1|Hwy 1]] East, [[British Columbia Highway 97|Hwy 97]] South, and [[British Columbia Highway 5|Hwy 5]] North. It is the only wrong-way concurrency in the province of [[British Columbia]].

====Saskatchewan====
* Near the town of [[Chamberlain, Saskatchewan|Chamberlain]], along [[Saskatchewan Highway 11|Highway 11]], there is a concurrency with [[Saskatchewan Highway 2|Highway 2]] such that 11 south is 2 north. [http://www.google.ca/maps?f=d&hl=en&geocode=&saddr=Hwy-11+%26+Hwy-2,+Chamberlain,+SK&daddr=HWY-11+%26+HWY-2,+Dufferin+No+190,+Saskatchewan,+Saskatchewan+S0G,+Canada&sll=50.798937,-105.416651&sspn=0.031735,0.093555&ie=UTF8&cd=1&z=13&om=1 Map]

====Quebec====
* From [[St-Patrice-de-Sherrington, Quebec|St-Patrice-de-Sherrington]] to [[Napierville, Quebec|Napierville]], Routes [[Quebec Route 219|219]] and [[Quebec Route 221|221]] run along the same physical road, but are signed in opposite directions. [http://www.google.ca/maps?f=d&hl=en&saddr=Rue+St-Patrice+%26+Rang+Ste-Marguerite,+Sherrington,+QC&daddr=RTE-221+%26+RTE-219,+Napierville,+QC&hl=en Map]

* Similarly, in [[St-Tite, Quebec|St-Tite]], Routes [[Quebec Route 153|153]] and [[Quebec Route 159|159]] are concurrent but are signed in opposite directions. [http://www.google.ca/maps?f=d&hl=en&saddr=Chemin+Haut-du-Lac+Sud+%26+Route+le+Bourdais,+St-Tite,+QC&daddr=Rue+le+Bourdais+%26+Boulevard+St-Joseph,+St-Tite,+QC&hl=en Map]

* Near [[Richmond, Quebec|Richmond]], Routes [[Quebec Route 116|116]], [[Quebec Route 143|143]], and [[Quebec Route 243|243]] run concurrently. However, Routes 143 and 243 are signed in opposite directions. [http://www.google.ca/maps?f=d&hl=en&saddr=Avenue+de+Melbourne+Nord+%26+Rte-116,+Richmond,+QC&daddr=Rue+Gouin+%26+Rte-143,+Richmond,+QC&sll=45.665938,-72.150489&sspn=0.003404,0.007231&ie=UTF8&z=17&om=1 Map]
