Central Subway is Open With Full Service as of January 7th, 2023

Beginning in 2013, the Central Subway Project (CSP) involved construction of a 1.7-mile extension of Muni’s T Third Line along 4th Street and beneath Stockton Street in downtown San Francisco. The CSP is Phase 2 of the San Francisco Municipal Transportation Agency’s (SFMTA) T Third Light Rail Transit (LRT) Project. The CSP extended 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 South of Market, Union Square, and downtown. 

On January 7th, the grand opening and ribbon-cutting ceremony signified full service operation of the underground project. This event was also attended by tons of people and prominent figures in the community including special guests, Nancy Pelosi, Mayor London Breed, former Mayor Willie Brown, City Attorney David Chiu, State Senator Scott Wiener, and other city supervisors and prominent figures in the community.
