San Francisco-Oakland Bay Bridge Eastbound Closure
Labor Day Weekend 2006

As part of its West Approach Seismic Retrofit Project, Caltrans will perform major demolition work on the Bay Bridge over Labor Day weekend. The eastbound direction (lower deck from San Francisco to the East Bay) of the Bay Bridge will be closed to traffic from 11:59 pm Friday, September 1 through 5 am Tuesday, September 5. The closure will be in the eastbound direction only. The upper deck will remain open to westbound traffic coming into San Francisco throughout the weekend.

Driving Alternatives

  • U.S. 101 South to the San Mateo-Hayward Bridge.
  • U.S. 101 north across the Golden Gate Bridge to I-580 and the Richmond-San Rafael Bridge.

The Bay Bridge closure may result in significantly increased northbound traffic across the Golden Gate Bridge. If this occurs, the public should also expect southbound delays across the Golden Gate Bridge as the roadway will be shared by heavy traffic in both directions likely resulting in three (3) traffic lanes for each direction. Typically, on Labor Day weekends, the Golden Gate Bridge is configured to accommodate high southbound traffic volumes with four (4) southbound lanes and two (2) northbound lanes.

Expanded Public Transit Options to East Bay during Closure

Travelers are advised to use BART to travel between San Francisco and the East Bay. BART will provide all-night service to a limited number of stations Friday night into Saturday, Saturday night into Sunday, and Sunday night through 1 am on Tuesday, September 5. Regular BART service resumes at 4 am on Tuesday, September 5. BART will run regularly scheduled service to all its stations during normal operating hours. This includes operating on a Saturday schedule on September 2 and a Sunday/Holiday schedule on September 3 and September. 4.

The Alameda-Oakland Ferry and the Vallejo Baylink Ferry will offer expanded services throughout the weekend.
