October 2007: San Francisco-Oakland Bay Bridge              San Francisco, California

    The San Francisco-Oakland Bay Bridge is principally a suspension bridge connecting San Francisco to Yerba Buena Island, and principally a cantilever span, with truss spans connecting that island to Oakland.  Designed by engineer Ralph Modjeski, it was built between 1933 and 1936.  The eastern cantilever and truss span is currently in process of replacement by an elevated, self-anchored suspension span.  For more information on this, see Bay Bridge Info.  The western suspension span is 9260 feet long and 220 feet above water level.
