About the Central Subway Project
The Central Subway Project will extend the T Third Line from the 4th Street Caltrain Station to Chinatown, providing a direct, rapid transit link from the Bayshore and Mission Bay areas to SoMa and downtown. Four new stations will be built along the 1.7-mile Central Subway Project alignment – a street-level station at 4th and Brannan streets and three subway stations: Yerba Buena/Moscone Station, Union Square/Market Street Station and Chinatown Station.
Travel times through this busy corridor will be significantly reduced by the Central Subway. During peak hours, current travel between Stockton and Washington streets and 4th and King streets takes more than 20 minutes on Muni trolley coach routes. On the Central Subway, the same trip will take less than eight minutes.
The Central Subway Project is the second phase of the SFMTA’s Third Street Light Rail Transit Project. The first segment of the T Third Line opened in April 2007, restoring light rail service to a high transit-ridership area of San Francisco for the first time in 50 years.
The Central Subway is expected to open to the public in 2019.
