Project Details

The Central Subway Project will improve public transportation in San Francisco by extending the Muni Metro T Third Line through SoMa, Union Square and Chinatown. By providing a direct, rapid transit link between downtown and the existing T Third Line route on 3rd Street, the Central Subway will vastly improve transportation to and from some of the city's busiest, most densely populated areas.

When the Central Subway is completed, T Third Line trains will travel mostly underground from the 4th Street Caltrain Station to Chinatown, bypassing heavy traffic on congested 4th Street and Stockton Street. Four new stations will be built along the 1.7-mile alignment:

  • 4th and Brannan Station at 4th and Brannan streets (street level)
  • Yerba Buena/Moscone Station at 4th and Folsom streets (subway)
  • Union Square/Market Street Station on Stockton Street at Union Square (subway)
  • Chinatown Station at Stockton and Washington streets (subway)

Construction will be in progress in SoMa, Union Square, Chinatown and North Beach until 2018. The Central Subway is scheduled to open to customers in 2019.
