Construction Update | January 4-13, 2014

131219_1009_Pagoda

At 1731-1741 Powell, we are constructing a retrieval shaft to remove two tunnel boring machines from the ground when tunneling is finished.

Next week traffic modifications on Stockton between Geary and Ellis streets near Union Square will recommence to accommodate construction of the Central Subway Union Square/Market Street station.

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, scroll down or click 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): We expect to begin potholing for utilities on 4th Street between Bryant and King in mid-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: Next week, Stockton Street between Ellis and Geary will be closed to vehicular traffic 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. On Jackson Street adjacent to Stockton Street, the contractor may be performing underground borings some nights next week.

North Beach: Work on Columbus Avenue at Union Street may resume next week. Work will continue at 1455 Stockton and 1731-1741 Powell, within the property lines.

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