Construction Update: Central Subway construction during the holiday season

This construction site near Union Square will be restored and reopened to traffic during the holiday season.

During the holiday season, construction at some currently active Central Subway construction sites will pause, with roadways and pedestrian walkways restored to regular use. At other sites, construction will continue.

This blog post provides a summary of construction impacts between Thanksgiving and New Year’s Day. For a complete listing of construction impacts, including work hours and traffic and pedestrian impacts, check out this press release from the SFMTA.

No construction will occur at any sites on Thanksgiving, Black Friday, Christmas Day or New Year’s Day.

Construction will continue at this site in SoMa, with the full closure of this block of 4th Street planned to remain in effect between Thanksgiving and New Year’s Day.

Here’s what you can expect in SoMa, Union Square, Chinatown and North Beach during the holiday season:

  • Union Square (Stockton Street between Ellis and Geary, Ellis Street between Stockton and Powell): Construction will pause at the site of the future Union Square/Market Street Station. Stockton Street and Ellis Street will be paved and reopened to traffic by Thanksgiving Day. After New Year’s Day, this section of Stockton Street will again close to traffic, and construction on Ellis Street will also begin again.
  • SoMa (4th Street between Harrison and Bryant): The contractor will work through the holiday season to construct a major excavation known as a launch box. 4th Street will remain closed to vehicle traffic. The sidewalk on the east side of the street will remain open to pedestrians. The on-ramp to westbound I-80 at 4th and Harrison may be closed on evenings and weekends.
  • SoMa (4th Street between Folsom and Harrison): Starting in December, the contractor will be excavating shallow trenches on the east side of the road and installing pipes to be used for ground improvement related to tunneling. The easternmost lane (left lane for southbound traffic) may be closed during limited times during construction hours (Monday to Friday, 6 a.m. to 10 p.m.).
  • SoMa (4th Street between Folsom and Howard): Construction of below-ground walls, called headwalls, at the site of the future Yerba Buena/Moscone Station will continue through the holiday season. At least three lanes on 4th Street will be open to traffic during regular construction hours (Monday to Saturday, 7 a.m. to 10 p.m.). Night work may occur, and traffic may be reduced to two lanes between 10 p.m. and 7 a.m. The sidewalk on the western side of the street may be impacted. Pedestrian detours will be provided.
  • Chinatown (Stockton Street between Sacramento and Vallejo): Construction will commence in December to install subsurface monitoring instruments related to the Central Subway tunnel. One lane on Stockton Street may be closed during construction hours in the vicinity of construction zones. Lane closures will impact traffic on up to two approximately half-block sections of Stockton Street at a time during construction hours (Monday to Friday, 10 p.m. to 7 a.m.)
  • North Beach (Columbus Avenue between Union and Filbert): This construction site will be paved and reopened to traffic by Thanksgiving. Central Subway crews will not be working in this area during the holiday season; however, AT&T may be performing work related to the Central Subway. AT&T’s work will involve a crew of approximately two people working inside manholes. No street excavation will occur as part of AT&T’s work.

We wish you a happy holidays, and we thank you for your continued patience as construction progresses.
