The Third Street Bridge, also known as the "Lefty O'Doul Bridge", is scheduled for rehabilitation work to sustain the integrity of the bridge and to address corrosion issues.
The project will involve; repairs or replacement of damaged steel members, welds, concrete counterweights, support piles, bridge fenders, spot removal of rust and associated priming and recoating, removal and replacement of the steel bridge deck and other associated work. This is a unique project that will involve the use of underwater divers, barges, rafts, temporary installation of protective barriers and containment curtains.
- 2017: Inspection and environmental clearance
- Fall 2017: Completion of design
- December 11, 2017 - January 26, 2018: Counterweight repair work
- Early 2018 - Spring 2019: Rehabilitation and construction activity begins
Construction activity on the main rehabilitation phase is anticipated to begin in early 2018 and is anticipated to last for approximately 18 months. At some points during the rehabilitation and construction phase, access to the bridge may be limited or closed to pedestrian, bicycle and vehicle traffic. We will be working closely with surrounding residents and businesses in the area to coordinate and minimize impacts during these anticipated closures. The bridge will remain open to pedestrians during San Francisco Giants home games.
Nighttime and weekend construction activity may be required. Full traffic plan with detours and alternative routes will be made available as the project nears.
*Please note that the construction schedule is subject to change due to rain, equipment breakdown, and/or unforeseen field conditions. Please see posted "No Parking" barricade signs for exact parking restrictions during construction.
12/04/2017: BRIDGE CLOSURE NOTICE - Crews will raise and lock the bridge in the full upright position to perform counterweight repair work on the Third Street Bridge starting on Monday, December 11, 2017. Access to cross the bridge will be closed to all pedestrian, bicycle and vehicle traffic during this period. Maritime traffic through the channel will not be impacted during counterweight repair work. Work is anticipated to continue through Friday, January 26, 2018. Parking control officers will be onsite to monitor traffic conditions and help direct traffic in the area surrounding the Third Street Bridge. SFMTA will restrict parking along the north side of Berry Street during this period and will install a temporary bicycle lane along the north side of Berry Street to accommodate rerouted traffic. Parking restrictions will be in effect 24-hours a day, Monday-Sunday and drivers are advised to not park or pull into the restricted area/bicycle lane. Normal parking continue to be available along the south side of Berry Street. Along the north side, drivers may pull into the designated white curb loading zone for active loading and unloading. Following completion of counterweight repair work, parking will be restored on the north side of Berry Street. Trash receptacles may be put into the designated crosshatch area on Berry Street (but not place into the bike lane) for collection as normal.
10/30/2017: The Third Street Bridge is anticipated to be closed and locked in the upright position between December 11, 2017 and January 26, 2018 to facilitate counterweight repair work. Additional restoration work anticipated to begin starting in early spring 2018. Work is being done during this off-season period to accomidate the San Francisco Giants and to minimize impacts to the general public. More details will be announced soon.
The bridge was temporarily closed on February 12, 2017 for bridge counterweight inspection work performed by TRC Solutions. During the inspection, the bridge was opened to the full open position and was closed to vehicle, bicycle and pedestrian traffic from 6:00 AM to 4:00 PM. Water access was open and accessible at all times to watercraft traffic.
More information about the project will be updated on this page as project details are finalized and made available to the public.
