The Central Subway project, targeted to open in summer 2021, will serve over 35,000 new customers per day. Central Subway will bring the T Third Street light rail line from its existing 4th Street and King Station into a new subway running beneath 4th and Stockton streets, terminating at Chinatown Station (Washington and Stockton streets). This new service will connect residents, visitors and businesses from Bayview, South of Market, Mission Bay to Financial District, Union Square, Moscone Center, and Chinatown.

As the Central Subway nears completion, the San Francisco Municipal Transportation Agency (SFMTA) is looking ahead at opportunities to extend subway service beyond Chinatown.

By year 2049, the City is projected to grow to nearly 1,000,000 residents. Therefore, the need for efficient public transit is great today and will continue to grow in the future. The Central Subway Extension is an opportunity for the SFMTA to evaluate a potential extension of the Central Subway beyond its current Chinatown Station terminal. Possible destinations include North Beach, Fisherman’s Wharf, the Marina, Cow Hollow, and Presidio.
