San Francisco Bay area commuters are getting out the door earlier than usual to try to avoid the traffic snarls expected because of the Bay Area Rapid Transit train strike.
Traffic leading up to the toll plaza of the San Francisco-Oakland Bay Bridge was heavier than usual around 5:30 a.m. Monday. People also lined up early to take buses that were leaving from a few Bay Area Rapid Transit stations.
Other roads and public transit options did not appear particularly crowded.
Two of BART's largest unions went on strike at midnight, halting train service for the first time in 16 years.
The walkout promised to derail the more than 400-thousand riders who use the nation's fifth-largest rail system and affect every mode of transportation.
