Oakland Bay Bridge startIn 1933, construction began on the Oakland Bay Bridge, California, U.S., to be a toll bridge across the San Francisco Bay linking Oakland and San Francisco. It is in effect two bridges connecting a central island, Yerba Buena Island, with each shore. From San Francisco, two suspension bridges end-to-end with a central anchorage reach the island, then traffic continues to Oakland over a truss causeway of five medium-span truss bridges and a double-tower cantilever span. The bridges were designed by Ralph Modjeski. It was opened for traffic on 12 Nov 1939, six months before the Golden Gate Bridge, which opened for traffic on 28 May 1937. At that time, the Oakland Bay Bridge made two world records: the longest suspended-deck bridge and the longest cantilever bridge.« |
