 About Us

 Bridges of the Bay Trail

The adopted Bay Trail alignment travels on seven of the eight toll bridges in the region. (The lone exception is the Antioch Bridge, which crosses Suisun Bay, east of the Bay Trail alignment.) All the bridges are owned by the State of California and administered by Caltrans, the state Department of Transportation, with the exception of the Golden Gate Bridge, which is owned and managed by the Golden Gate Bridge, Highway and Transportation District.

Bicycle and pedestrian access is allowed on five of the seven bridges:

Carquinez Bridge
There is a two-way, 12-foot-wide separated path for bicyclists and pedestrians on the west side of the span; the distance is 0.8 miles.

Benicia-Martinez Bridge
There is a two-way, 12-foot-wide separated path for bicyclists and pedestrians on the west side of the bridge; the distance is 1.2 miles.

Dumbarton Bridge
There is a two-way, eight-foot wide separated path for bicyclists and pedestrians on the south side of the bridge; the distance is 3.4 miles.

Golden Gate Bridge
Bicyclists and pedestrians are allowed to cross using the sidewalks; check goldengatebridge.org/bikesbridge/bikes.php for restrictions dictating which sidewalk must be used depending on the time and day of the week. The length of the bridge is 1.2 miles (1.7 miles including the approaches).

San Francisco-Oakland Bay Bridge
East Span: There is a two-way, 15-foot wide separated path on the south side of the new East Span between Oakland and Yerba Buena Island. The path does not yet connect to Treasure Island because the old bridge span needs to be demolished to make room for the new path extension to the island. Caltrans expects to open the entire path in 2015. Periodic closures of the path will occur during the bridge demolition. Once completed, the pathway will extend for 2.2 miles between Oakland and Treasure Island. See this website for up-to-date information: baybridgeinfo.org/bicycle-and-pedestrian-path

West Span: Bicyclists and pedestrians are not allowed on the West Span. In December 2011, the Bay Area Toll Authority (BATA), in partnership with Caltrans and the City and County of San Francisco, developed several design alternatives for a bicycle/pedestrian/maintenance path project on the West Span of the San Francisco-Oakland Bay Bridge.

Caltrans operates a Bay Bridge bike shuttle during peak commute periods. At other times, bikes may be carried on BART or AC Transit. For more information, visit www.dot.ca.gov/dist4/shuttle.htm

San Mateo-Hayward Bridge
Bicyclists and pedestrians are not allowed. AC Transit runs bus line M across the bridge. See www.actransit.org for details.

Richmond-San Rafael Bridge
Bicyclists and pedestrians are not allowed. Golden Gate Transit operates buses equipped with bike racks, goldengatetransit.org/services/bikes_cyclistsroute40.php. In December 1998, a public access feasibility study was completed, which recommended near-term use of the existing shoulders for non-motorized uses, and, in the long term, a separated two-way path.
