With the BART transit system on strike, traffic is backed up for blocks on Bush Street leading to an artery of the San Francisco-Oakland Bay Bridge during the evening commute Friday, Oct. 18, 2013, in San Francisco. San Francisco Bay Area rapid transit workers are on strike for the second time since July, scrambling the morning commute for hundreds of thousands of workers who were up before dawn to clog highways, swarm buses and shiver on ferry decks as they found alternative ways to the office. About 400,000 riders take BART every weekday on the nation's fifth-largest commuter rail system.
