During the next 10 days, Central Subway work will continue at sites in SoMa, Union Square, Chinatown and North Beach. This section contains brief updates about what is happening in each neighborhood.

Southern SoMa (Harrison to King/Berry): Potholing for utilities will continue next week on 4th Street between Bryant and King. A temporary walkway is in place around the construction zone. At the tunnel launch box on 4th Street between Harrison and Bryant, tunneling continues with both TBMs.
Northern SoMa (Market to Harrison): On 4th Street between Market and Stevenson, and 4th Street between Folsom and Harrison, roadway restoration work is now complete. At 4th and Folsom, work to prepare for the Yerba Buena/Moscone Station continues. This will include soil test drilling at 4th and Folsom at night, as well as 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. Work is underway to excavate material before constructing station walls. Construction hours will be Monday to Friday from 7 a.m. to 11 p.m.
Chinatown: The contractor will start station wall construction within the future station site and on the adjacent section of Washington Street.
