Salesforce Transit Center (Transbay Transit Center)
425 Mission Street, San Francisco, CA 94105
The 2007 design paired a bus terminal with a train box for a future Caltrain and high-speed-rail extension. The terminal opened in 2018, briefly closed after cracks were found in beams supporting the bus deck, and reopened in 2019. The rail extension remains unbuilt, but a January 2026 federal commitment moved it beyond two-thirds funded and active engineering continued.

What changed
- The design selected September 20, 2007 included an underground train box for six tracks and three island platforms serving a future Caltrain extension and California high-speed rail.
- The center opened August 12, 2018 serving buses, while the separately funded rail extension remained unbuilt.
- The facility closed September 25, 2018 after cracks were found in steel beams supporting the bus deck, not the train box; buses resumed July 13, 2019 and the full building reopened August 11, 2019.
- In January 2026, TJPA announced a $3.4 billion federal commitment for The Portal and said the project was more than two-thirds funded.
- In February 2026, San Francisco County Transportation Authority materials documented a $12.5 million Proposition L allocation for engineering activities.
- As of August 11, 2026, The Portal remained unbuilt but was in engineering, preconstruction and continuing funding development rather than awaiting any funding at all.
Why it changed
The bus-terminal and rail-extension phases followed separate funding paths. The terminal opened before the extension was built, but a January 2026 federal commitment brought The Portal to more than two-thirds funded and supported continued engineering and preconstruction work.
