Doyle Drive Bridge
Posted April 22, 2013, by Nathan Holth (form3 [at] historicbridges [dot] org)

The demolition of this bridge and replacement with a slab of concrete is deeply disappointing. Even though its not physically connected to the Golden Gate Bridge, it is part of the Golden Gate Bridge project. For proof of this you need not look further than the main plaque for the Golden Gate Bridge, which lists the builder for the "Presido Approach Roads and Viaducts" They are basically demolishing part of the Golden Gate Bridge.
