Are the Golden Gate Bridge and Bay Bridge seismically retrofitted?
The Golden Gate Bridge is currently undergoing a sequence of retrofits, some of which have already been completed. The process has reached the point that the Golden Gate Bridge no longer faces the potential for collapse. Until all the retrofit steps have been completed, the Main Suspension Bridge may be damaged significantly in a major earthquake. Check for updates at the website of the Golden Gate Bridge. The new eastern section of the Bay Bridge, which is expected to open in 2013, is being built to withstand a major earthquake. The retrofit of the western segment has been completed. The Bay Bridge is considered an emergency “lifeline” route to be used in disaster response activities. Thus, when completed, it will be able to reopen quickly following an earthquake.
