San Francisco-Oakland Bay Bridge
The San Francisco-Oakland Bay Bridge is the region's workhorse bridge, carrying more than a third of the traffic of all of the state-owned bridges combined. It is also a jewel along the San Francisco waterfront.
The San Francisco-Oakland Bay Bridge is made up of two bridge segments: a skyway structure/single anchored suspension bridge between Oakland and Yerba Buena Island, and a suspension span from the island to San Francisco. Connecting the two is the largest diameter bore tunnel in the world.
The design of the new East Span — which opened in September 2013 — features a single-tower, self-anchored suspension bridge for the segment of the bridge that crosses the shipping channel, and a skyway structure over the shallower waters close to the Oakland shore.
Due to unforeseen construction conditions encountered during construction of the new bicycle path on Yerba Buena Island as part of the Southgate Road Realignment Project there will be no bicycle or pedestrian access between Yerba Buena Island and Treasure Island until Mid-November 2021. This means no access on weekdays, weekends and holidays through mid-November 2021.
Seismic retrofit of the West Span of the San Francisco-Oakland Bay Bridge was completed in 2004. The original East Span was damaged in the 1989 Loma Prieta earthquake and subsequently repaired. The replacement East Span opened on September 2, 2013.

This regional measure, approved by Bay Area voters in 1988, raised tolls on the Bay Area’s seven state-owned toll bridges to fund bridge improvements and parkway construction.
The Bay Bridge Trail carries bicyclists and pedestrians across the majestic East Span, connecting the Oakland shoreline with Yerba Buena Island.
