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. 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): 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)At 4th and Folsom, work to prepare for the Yerba Buena/Moscone Station continues. This will include demolishing the roadway within the construction zone to prepare to construct underground station walls at 4th and Folsom at night.

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.
