In a parking lot at Stockton and Green, crews have built this underground shaft. From it, we will improve and stabilize ground conditions beneath Columbus Avenue during tunneling.

Due to the upcoming holidays, this update covers the next two weeks of Central Subway work. There will be no update next Friday, Dec. 27. Happy holidays from the Central Subway team!

During the next 17 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.

In honor of Christmas and New Year’s Day, no construction will take place on Dec. 25 or Jan. 1. Starting in the new year, work will recommence on Columbus Avenue in North Beach and on Stockton Street in Union Square.

Southern SoMa (Harrison to King/Berry): We now expect to begin potholing for utilities on 4th Street between Bryant and King in January. At the tunnel launch box on 4th Street between Harrison and Bryant, tunneling continues with both TBMs.

Northern SoMa (Market to Harrison): We plan to begin restoring 4th Street between Folsom and Harrison during the next two weeks. Until then, the traffic pattern may change to allow for underground sewer surveys. 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.

Union Square: Construction is now paused on Stockton Street, resuming in January. Stockton Street between Ellis and Geary is tentatively planned to close to vehicle traffic on Thursday, Jan. 2, to allow for construction of the Union Square/Market Street Station. The construction zone on Ellis Street will remain in place.

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

North Beach: On Columbus Avenue at Union Street, construction is planned to resume Thursday, Jan. 2. Work will continue at 1455 Stockton and 1731-1741 Powell, within the property lines. No construction is planned at 1731-1741 Powell from Christmas to New Year’s Day.
