SAN FRANCISCO - OCTOBER 29: Commuters board a Bay Area Rapid Transit (BART) train during rush hour on October 29, 2009 in San Francisco, California. Thousands of Bay Area commuters were hampered by a second day of difficult commuting after the San Francisco Bay Bridge was abruptly closed the evening of October 27, when 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. No estimated time has been set for the bridge to reopen. The eastern span of the bridge is undergoing seismic renovation and is expect to be completed in 2013.
