San Francisco-Oakland Bay Bridge Seismic Safety Retrofit Project

Last updated 1/28/2013

Caltrans continues to work on the large seismic safety project to rebuild and reinforce the San Francisco – Oakland Bay Bridge. As part of this project, the two-mile-long East Span is being completely rebuilt. When completed, the new East Span will consist of several different sections, but will appear as a single streamlined span. The new span will feature a Self-Anchored Suspension (SAS) section connected to a roadway supported by piers (Skyway), which will gradually slope down towards the Oakland Shoreline (Oakland Touchdown).

Construction on the Bay Bridge is ongoing. In May 2011, crews realigned eastbound lanes by building a detour near the Toll Plaza for traffic heading to the East Bay. Once eastbound traffic had been safely shifted, workers built the westbound detour, which went into effect over Presidents' Day weekend, 2012. Shifting traffic onto the detours will allow construction of the new East Span to be completed ahead of schedule. With westbound traffic moved to the new alignment, crews can finish the easternmost part of the new bridge and open the new span to all motorists in late 2013.
