The Bridge
The San Francisco-Oakland Bay Bridge is a 13km crossing from San Francisco to Oakland. The western section is two double-decked suspension bridges, each of 704m main span, connected to a central anchorage. These were designed and overseen by the engineer, Charles Purcell, in the 1930s.
The crossing then enters a tunnel at Yerba Buena Island before the eastern section, a single-anchored suspension bridge with a long viaduct, reaches Oakland. This section is a new replacement bridge that opened in 2013. It is 10 lanes wide on a single-deck across the shallower waters to the Oakland shore.
