Spear Street at Mission - The Spear Street/Mission Street intersection will be closed to through traffic this weekend, October 18-19. Beginning about 7:30 a.m. on Saturday and Sunday, traffic will be detoured around the construction area. Actual construction hours will be 8 a.m. to 8 p.m. both days. After 8 p.m. Saturday, clean-up of the site may continue until midnight. On Sunday, crews may work until 8 p.m. if necessary to finish work in the intersection so it can be re-opened to traffic at midnight.
WHAT TO EXPECT:
• Some noise and vibration as shoring panels are removed.
• Concrete pouring of a new road base. Steel plates will remain in the intersection until the concrete cures. Then the steel plates will be removed and the concrete base temporarily paved over. This temporary paving will remain in place until the completion of the project when the street permanent surface will be restored.
• Detour signs will be posted for drivers and pedestrians.
• To maintain access for residents and businesses to their garages and driveways, local traffic will be configured as a series of cul-de-sacs. Please see the map posted on our website for details.
• AT&T will be on site to locate their facilities.
Spear Street Market to Mission - There is a continuing interruption to the force main work on this block due to discovering unmarked utility lines. The contractor and city staff are working with utility providers to resolve the conflicts so project work can continue.
Spear Street at Howard - Construction crews finished the installation of two new catch basins at the northeast corner of Spear and Howard Streets. These will help mitigate stormwater flows. This temporary paving will remain in place until the completion of the project when the street permanent surface will be restored.
Drumm Street - Concrete base has been poured adjacent to the cable car turn-around at California/Market streets, in preparation of brick work. The sidewalk base work in front of EC4 is being prepared for the installation of the tiles.
Project's Regular Work Days & Hours: Monday through Friday, 8:00 A.M. to 8:00 P.M. (notification will be provided for weekend/night-work)

The existing North Shore force main serves more than 350,000 people by transporting combined wastewater – sanitary sewage and stormwater – from the northeast part of San Francisco to the Southeast Wastwater Treatment Plant for treatment. The existing force main is near the end of its useful life and in need of repair. The completion of this new sewer project will enable the rehabilitation of the existing sewer line and ensure continued service to residents and businesses of San Francisco.

Comparing the Embarcadero wharf from centuries ago with today’s built up environment, helps us understand the difficulties the design engineers and contractor constantly struggle with as they encounter unmarked piers, buried brick sewers and other remains from the 1800s.
