Planned to open on January 7, 2023, the Muni Central Subway project will extend the T-Third light-rail line with four new stations on a 1.7-mile extension from the 4th and King/Caltrain station to Chinatown.

MTC made the $1.57 billion Central Subway project a top regional priority in the competition for funding through the Federal Transit Administration’s New Starts program.

And MTC played a central role in getting this new project underway, by:

  • Identifying it as an original Regional Transit Expansion Policy priority project
  • Including it in the voter-approved Regional Measure 2 expenditure plan
  • Delivering $30 million in toll dollars, plus ongoing operations support once the extension opens

Value to the Community

Completion of the Central Subway will provide a direct rapid transit link between downtown San Francisco and the Sunnydale, Visitacion Valley and Bayview neighborhoods.

These neighborhoods will enjoy better access to jobs, stores, schools, and sporting and cultural venues in downtown San Francisco, Chinatown, South of Market and Mission Bay.

Completion of the project will:

  • Improve regional connections to BART, Caltrain and future high-speed rail
  • Increase transit capacity and relieve overcrowding
  • Improve travel times
  • Relieve congestion along the Stockton Street corridor
  • Reduce air and noise pollution
  • Stimulate economic activity along the 4th Street corridor south of Market Street

The Central Subway project received a total of $942 million through the Federal Transportation Administration’s New Starts program. Other funding partners include:

  • MTC
  • State of California
  • San Francisco County Transportation Authority
  • City and County of San Francisco
