Spear Street Closure
San Francisco Public Utilities Commission (SFPUC) has closed Spear Street from Market to Mission streets to all but local traffic.  The street will stay closed intermittently through Spring 2015. 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)
To help speed the construction process under Spear Street, we plan to close the Mission/Spear intersection for the entire three-day Labor Day Weekend (Saturday, Sunday and Monday) to continue obstruction removal at that location. The construction crews will open Mission Street from Main to Steuart Streets to regular traffic each evening after crews complete work (10pm or earlier). The intersection will be closed again the following mornings at 7 a.m. and remained closed until crews complete work for that day. Another change from last week’s configuration is that there will be a special Muni-only lane through the Mission/Spear intersection during day work, however the intersection will still be closed to vehicular traffic during the work window. Just like the previous two weekends, cul-de-sacs will be provided for local traffic on Spear and Mission Streets one block in each direction from the intersection. 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
We are working hard to complete restoration activities along Drumm Street. In the coming weeks, the Contractor plans to complete the remaining paving work. Custom tiles have also been ordered for the restoration of special tiles in front of the Hyatt and EC4. Additional restoration elements include median landscaping and tree replacement to restore the area to its pre-construction condition. We appreciate your patience as our team works hard to complete the restoration of Drumm Street.

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.
