San Francisco-Oakland Bay Bridge

The San Francisco-Oakland Bay Bridge, on Interstate 80, crosses the San Francisco Bay and connects San Francisco and Alameda counties It is made up of two bridge segments: a skyway structure/single anchored suspension bridge between Oakland and Yerba Buena Island for vehicles with a protected bicycle and pedestrian pathway, and a suspension span from the island to San Francisco for vehicular traffic. 

Through summer 2022, access to Treasure Island via the Bay Bridge Eastern Span will be reduced due to ongoing construction work. Visit our Bay Bridge Trail page for additional information.
