Spear Street Closure (weekdays)
San Francisco Public Utilities Commission (SFPUC) has closed Spear Street from Market to Mission streets to all but local traffic. Crews have posted No Parking signs and lane markers for local traffic use. All property owners and tenants will continue to have access to their garages/driveways for the duration of construction. However, vehicles will NOT be able to make stops, pick-up or drop-off passengers except within their own garages or parking lots. No parking will be allowed on either side of Spear Street between Mission and Market streets, and any parked vehicles will be ticketed and towed. Pedestrian traffic will continue to have full sidewalk access; just follow posted signs.

Muni buses have been rerouted to accommodate this work. For information call 311 or visit

Spear Street and Mission intersection (weekends)
On weekends only, including August 23-24 and continuing through late Fall 2014, the SFPUC plans to shut down the Mission/Spear Street intersection to through traffic. Closures will begin Saturday mornings at 7 a.m. and continue through Monday mornings at 5 a.m. Please note this reconfiguration will take place on WEEKENDS ONLY. Additional weekend closures are expected and more information will be released when confirmed.

On Weekends only: Spear Street from Market to Mission will become a cul-de-sac with entrance and exit from Market Street.  Spear Street from Mission to Howard Street will become a cul-de-sac with entrance and exit from Howard Street. We have posted an alternate route map at right; click on "Spear St Detour". The traffic pattern as described above (Spear Street from Market to Mission closed to through traffic) will be in place Monday through Friday.

Drumm Street
The Drumm Street Detour has been removed and two-way traffic from California to Clay has been restored. The SFPUC contractor will continue to perform restoration work on Drumm Street (curbs, gutters, sidewalks, median) through the summer. At the corner of Drumm and Washington streets, the SFPUC is rebuilding the catch basin and installing handicapped ramps for pedestrians.

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)

Project Description

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.
