Third Street Bridge Rehabilitation Project

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. 

Project Timeline*:
- 2017: Inspection and environmental clearance 
- Fall 2017: Completion of design
- Early 2018 - Spring 2019: Rehabilitation and construction activity begins

Construction activity 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. 

Project Activity:
10/30/2017: PENDING BRIDGE CLOSURE 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 start in early 2018. Work is being done during this period to accomidate the San Francisco Giants duirng the off-season 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.
