A reversible lane is a managed lane in which traffic may travel in either direction, depending on certain conditions. Typically, it is meant to improve traffic flow during rush hours, by having overhead traffic lights and lighted street signs notifying drivers which lanes are open or closed to driving or turning.

The Lions Gate Bridge, opened in 1938 and officially known as the First Narrows Bridge, is a suspension bridge that crosses the first narrows of Burrard Inlet and connects the City of Vancouver, British Columbia, to the North Shore municipalities of the District of North Vancouver, the City of North Vancouver, and West Vancouver. The term "Lions Gate" refers to the Lions, a pair of mountain peaks north of Vancouver. Northbound traffic on the bridge heads in their general direction. A pair of cast concrete lions, designed by sculptor Charles Marega, were placed on either side of the south approach to the bridge in January 1939.
