Central Subway

Central Subway

The Central Subway is an extension of the Muni Metro light rail system in San Francisco, California, from the Caltrain commuter rail depot at 4th and King streets to Chinatown. The subway is the second phase of the Third Street Light Rail Project. Still in its planning stages, the Central Subway is currently scheduled for completion by 2016.

Alignment

In February 2008, the Municipal Transportation Agency board voted to select Alternative Alignment 3B for the subway.cite web

] In this alignment, trains will travel north on Fourth Street, stop at an above-ground station at Fourth and Brannan, and enter the subway through a portal on Fourth between Bryant and Harrison Streets, under Interstate 80. The route will then continue under Fourth Street through South of Market, and have an underground station at the Moscone Center. At Market Street, the subway will dip below the Market Street Subway and there will be another underground station serving Market Street and Union Square underneath Stockton Street. This combined Market Street/Union Square station will have entrances at the Market, Ellis and Stockton intersection, and at Stockton and Geary, and will have a pedestrian passage connecting it to the Muni Metro and BART Powell Street Station. North of there, the subway will continue under Stockton with a station located in Chinatown at Stockton and Jackson Streets.

Chinatown subway plan gets agency's nod] ] If approved, the tunnel might continue farther north on Stockton and Columbus to Washington Square, making a potential extension north easier as well as easing removal of the tunnel boring machine.

In the future, the line could be extended further north to North Beach and Fisherman's Wharf.

Cost

Due to the capital cost ($1.4 billion for the 1.7 mile light rail line), the Central Subway project has come under criticism from transit activists for what they consider to be poor cost-effectiveness.cite web

*Muni would have to spend an additional $4 million/year in local operating subsidies (over existing bus service) to run the new rail line. [http://www.examiner.com/a-833889~One_man_s_plan__Stockton_bus_only_lanes.html Stockton Bus Only Lanes] ]
