Richmond - San Rafael Bridge

They've both had a seismic retrofit to withstand earthquakes. I don't see why they would be demolished or collapse anytime soon.

I wonder what the future holds for this bridge and the Carquinez Strait Bridge. The eastern Oakland Bay bridge was replaced saying because it was not earthquake safe. That deck collapse could have happened to the suspension bridges too. The cantaleiver truss bridges are just as great as the wire suspension bridges. I just dont fully understand what they think would happen in an earthquake. The two bridges I mentioned should be left alone except for needed repairs.
