The Central Subway Project is the second phase of the SFMTA Third Street Light Rail Transit Project. Phase 1 of the project constructed a 5.2-mile light rail line along the densely populated 3rd Street corridor. This segment of the T Third Line began revenue service in April 2007, restoring light rail service to a high transit-ridership area of San Francisco for the first time in 50 years.
Revenue service on the Central Subway is expected to begin in 2019.
