hwy markerThe San Francisco-Oakland Bay Bridge, known locally as 'The Bay Bridge', is technically only about five miles across water, including the crossing near Treasure Island. To show access points, mileage for this roadway is calculated from the downtown San Francisco interchange of Interstate 80 and US Highway 101, and the Oakland interchange of I-80/I-880 and I-580. These are the major interstate access points to the San Francisco-Oakland Bay Bridge.
Entrances and exits, particularly in downtown San Francisco and near The Embarcadero, are shown on the maps for this roadway to help provide high-quality navigational reference points, as well as make it easier to make use the toll calculators, by providing starting and stopping points for drivers to use for the calculation.
The bridge is, itself, only tolled in the westbound direction, and only on the eastern span, which connects Oakland with Yerba Buena Island via I-80. Additionally, drivers passing Treasure Island will, literally, pass through the adjacent Yerba Buena Island via a short tunnel.
