Central Subway Alignment

The Central Subway Project will provide a direct transit link between the Bayshore and Mission Bay areas to SoMa, downtown, and Chinatown.

Four new stations will be constructed as part of the Central Subway Project:

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

The Union Square/Market Street Station will connect to the existing Powell Street BART/Muni Station, allowing for convenient transfers to BART, the Powell Street Cable Car Line,Muni Metro lines and Muni bus routes in the area.

The Central Subway will provide rapid north-south service, in contrast to the principally east-west routes currently in service along Market Street.

It will also facilitate direct transfers to local and regional transit options:

• Caltrain (and, in the future, high-speed rail service) at 4th and King streets
• BART at Powell Street Station. 
• Muni Metro’s J, K, L, M and N lines at Powell Street Station
• Powell Cable Line above Powell Station
• Muni bus and electric trolley routes, including the 8X/8AX/8BX Bayshore Express, the 14/14L/14X Mission and the 38/38L Geary lines

The Central Subway will run through the burgeoning technology and digital-media hub in SoMa, where dozens of companies have taken up residence along the 4^th Street corridor. Increased transit options will attract new employers because the Central Subway makes travel more convenient throughout the corridor and improves connections to downtown, as well as to local and regional rail and the Muni bus system.
