WHY DOES THE GOLDEN GATE BRIDGE USE REVERSIBLE LANES?
Reversible lanes were inaugurated on the Bridge on October 29, 1963. Their use greatly aids the flow of traffic during the heavy morning and evening commute hours and during weekend tourist periods. The Bridge has a total of six lanes. At any given time the number of lanes northbound or southbound may be adjusted. Bright yellow lane markers are manually placed in “sockets” in the Bridge roadway to clearly identify the San Francisco outbound lanes (northbound) and San Francisco inbound lanes (southbound). During the morning commute there are four lanes of traffic southbound to San Francisco and two lanes northbound to Marin. During the afternoon commute there are four lanes northbound to Marin and two lanes southbound to San Francisco.
