Caption: "San Francisco Bay Bridge Under Construction. Nov. 1, 1935." View of the towers and suspension cables of the western half of the San Francisco-Oakland Bay Bridge, spanning the distance between Yerba Buena Island in San Francisco Bay to the City of San Francisco. The bridge deck has not yet been completed. The Bay Bridge's design combined three different types of bridge-building technology over the five miles it covers between San Francisco and Oakland: a suspension span, a cantilevered span, and a tunnel. At the time of its completion in 1936, the bridge was the longest steel structure on the globe. It also featured the deepest bridge pier ever built, and the world's largest bore tunnel.
