Transbay Transit Center

Conceived as the “Grand Central Terminal” of the West, the Salesforce Transbay Transit Center first opened to the public and to transit operators in August of 2018. It subsequently closed for nine months to allow the Transbay Joint Powers Authority (TJPA) to inspect and repair damaged girders, and reopened in July of 2019.

The Salesforce Transit Center officially opened with a weekend of festivities in August 2018, but closed temporarily in October of 2018 when flaws were discovered in two key beams supporting the bus deck and the rooftop garden. The first phase of the facility features features:

  • A third-floor bus deck
  • Ground floor and concourse level retail space (still in progress)
  • Two below-grade levels to eventually serve Caltrain and the California High-Speed Rail system
  • A 5.4-acre rooftop park

Phase 2 of the 1 million square foot project will include construction of the Downtown Rail Extension to be used by Caltrain and High-Speed Rail trains. The Phase 2 construction schedule will depend on availability of full funding for the project.

Initially the new transit hub will be served by:

  • AC Transit
  • Amtrak
  • BART
  • Golden Gate Transit
  • Greyhound
  • San Francisco Muni
  • SamTrans
  • WestCAT

Development of the project is overseen by the six-member Transbay Joint Powers Authority, which includes representatives from:

  • San Francisco Mayor’s Office
  • San Francisco Board of Supervisors
  • Muni
  • AC Transit
  • Caltrain
  • California Department of Transportation
