应该是Reversible Center Lane

Reversible Center Lane is a vertical three-lane, two-way roadway is shown. Arrows show that the direction of travel in the left lane is southbound, the right lane is northbound, and the center lane can be either. Broken double yellow lines are shown separating the lanes from each other. A legend shows a black arrow indicating the direction of travel in the lanes.
