The San Francisco-Oakland Bay Bridge spans the San Francisco Bay and links the California cities of Oakland and San Francisco in the United States. The bridge consists of two major segments connecting a central island, Yerba Buena Island, with each shore. The western segment terminating in San Francisco consists of two suspension bridges end-to-end with a central anchorage. The eastern span terminating in Oakland consists of a truss causeway, five medium-span truss bridges and a double-tower cantilever span, scheduled to be replaced by an entirely new structure now under construction. The original bridges were designed by Ralph Modjeski. The bridge was built at the same time as San Francisco's other famous bridge – the Golden Gate.
