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

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

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.

Muni forecasts:

Daily ridership along the T-Third light-rail by 2019: 43,700

By 2030: 65,000

More than half of these riders will be along the Central Subway segment of the route.
