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.
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 [[Interstate 495 (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.
