One of the preeminent engineering feats of the twentieth century, it was built in the 1930s and actually consists of several bridges joined end-to-end. The first stretch consists of two end-to-end suspension bridges (a bridge with a roadway suspended from cables supported by structures at each end but which has no supporting structures under the length of the bridge itself) going from San Francisco to Yerba Buena Island in the middle of the bay. The roadway then passes through a tunnel in the island and on the other side the bridge continues from Yerba Buena to Oakland. The bridge has two levels for traffic and in total extends eight miles.a bridge which spans across the San Francisco Bay in western California, between the cities of San Francisco and Oakland.
