OAKLAND, CA - OCTOBER 28: California Highway Patrol officer Rick Baller walks to his car as he guards the closed toll plaza leading to the San Francisco Bay Bridge October 28, 2009 in Oakland, California. The San Francisco Bay Bridge was abruptly closed Tuesday evening after two steel tie rods and a crossbeam from a steel saddle broke and fell onto the upper deck of the bridge landing on three vehicles and causing one person to suffer injuries. The eastern span of the bridge is undergoing seismic renovation and is expect to be completed in 2013.
