Transbay Transit Center

+

The one million square-foot Transbay Transit Center in downtown San Francisco will transform transportation in California by creating the “Grand Central of the West.” As the largest approved public transportation project in the country, the $4 billion program will replace the current Transbay Terminal at First and Mission streets in San Francisco with a modern regional transit hub connecting eight Bay Area counties and the State of California through nine transit systems: AC Transit, BART, Caltrain, Golden Gate Transit, Greyhound, MUNI, SamTrans, WestCAT and future High Speed Rail from San Francisco to Los Angeles. Additionally, it will extend Caltrain and California High Speed Rail underground from Caltrain’s current terminus at 4th and King streets into the new downtown Transit Center and create a new neighborhood with homes, offices, parks and shops surrounding the new Transit Center.

Webcor/Obayashi, Joint Venture is the CM/GC for Phase I including the construction of a new five-story Transit Center Building with one above-grade bus level, ground-floor, concourse, and two below-grade rail levels serving Caltrain and the future California High Speed Rail. It will also include a 5.4 acre public rooftop park.

Phase I also includes construction of new bus ramps that will connect the Transit Center to a new off-site bus storage facility and the San Francisco-Oakland Bay Bridge. The first phase of the project is fully funded at $1.589 billion and is being funded through local, regional, state and federal sources.
