Is the Bay Bridge the only Bay Area Bridge that is undergoing a seismic retrofit?
The California Department of Transportation has completed retrofits on four other major Bay Area bridges: the San Mateo-Hayward Bridge, the Richmond-San Rafael Bridge, the Carquinez Bridge, and the Benicia-Martinez Bridge, as well as numerous, smaller state-owned overcrossings, undercrossings and interchanges that comprise the highway network. The Golden Gate Bridge is also undergoing a seismic retrofit, which is being managed by the Golden Gate Highway, Bridge and Transportation District. Preliminary seismic safety studies have also been performed on the Antioch and Dumbarton toll bridges, but comprehensive analyses must be performed to make the final determination of the level of retrofit work required.
