wrong-way concurrencies

错误方向并发, 反向重叠

a situation where two or more numbered highways overlap along the same stretch of road but are signed with opposing cardinal directions

Wrong-way concurrency occurs when two or more numbered highways share the same roadway while being signed with opposing cardinal directions (e.g., one marked "North" and the other "South" along the same stretch). This inconsistency arises due to historical route numbering, jurisdictional compromises, or geographical constraints that prevent logical directional alignment. These anomalies are often remnants of older highway systems that were later integrated into modern networks without directional adjustments. Examples include segments where US highways and state or provincial routes intersect in urban areas or mountainous terrain.
