contraflow lane
n. On a road or highway, a lane that accepts traffic driving in different directions, depending on the time of day.
Police were forced to close a section of the eastbound carriageway of the M8 in Lanarkshire on safety grounds after its hard shoulder, being used as a contraflow lane, developed large cracks and a number of potholes.

The new "contraflow" lane restricted to high-occupancy vehicles is one of only two such highway configurations in the nation. It will provide five lanes of traffic inbound during morning rush hours, with three outbound. Through a system of moveable concrete barriers, the lanes will be switched for the evening rush hours, with five lanes of traffic going south, or outbound.
