TBM Big Alma is crossing under Market Street and BART this week. This photo shows the back of the TBM as it approaches this key juncture.

During the next 10 days, Central Subway work will continue at sites in SoMa, Union Square, Chinatown and North Beach. This post contains brief updates about what is happening in each neighborhood. For more detailed information, click here or on the links below. We also post construction, traffic detour and Muni impact information on our project Google Map.

Southern SoMa (Harrison to King/Berry): This week we began potholing for utilities on the east side of 4th Street between Bryant and Bluxome. Work will continue in this area next week. At the tunnel launch box on 4th Street between Harrison and Bryant, tunneling continues with both TBMs.

Northern SoMa (Market to Harrison): Construction will continue on 4th between Market and Stevenson as the second TBM passes through the area. On 4th Street between Folsom and Harrison, the road expected to reopen in February. At 4th and Folsom, work to prepare for the Yerba Buena/Moscone Station continues. Work may include demolishing the roadway within the construction zone to prepare to construct underground station walls. This work will be noisy.

Union Square: Stockton Street between Ellis and Geary is closed to vehicular traffic to allow for construction of the Union Square/Market Street Station. On Ellis Street, crews may work through the weekend as the second TBM crosses under Market Street. On Stockton Street, crews will work on Saturday mobilizing equipment to the construction zone.

Chinatown: Work to prepare for the Chinatown Station continues within the future station site and on the adjacent section of Washington Street.

North Beach: Next week work will continue at Columbus & Union, 1455 Stockton and 1731-1741 Powell. At 1731-1741 Powell, construction may be in progress on Saturdays from 7 a.m. to 5 p.m.

We appreciate your patience and support while we build this essential upgrade to San Francisco’s public transportation system.
