The Third Street Bridge Rehabilitation Project will soon begin Phase II of rehabilitation work planned for Lefty O’Doul Bridge on 3rd Street between Berry Street and Terry A Francois Boulevard. Phase I was completed between December 2017 and January 2018 and involved counterweight repairs.
American Bridge Company has been selected as the general contractor to perform next phase of bridge rehabilitation work and anticipates rehabilitation work will begin in early October 2018 and continue through December 2019.
Additional construction details and project information will be available on the project web page at www.sfpublicworks.org/thirdstr
As we prepare to begin rehabilitation work, please note the following significant dates:
You may start to notice engineers and contractors around the bridge in the coming weeks to perform some pre-construction assessment work to document the current condition of the bridge mechanical systems, steel members, and in-water pile systems prior to the actual start of rehabilitation work. This work is anticipated to take place between Tuesday September 4th, 2018 and Friday, September 7, 2018 between the hours of 10 AM and 2 PM. During preliminary assessment work, crews may need to temporary lift the bridge or restrict vehicular, bicycle and pedestrian traffic across the bridge for short periods of time, i.e. traffic restrictions may be in 10-15 minutes increments over the course of the mid-day non peak traffic periods. Please expect minor intermittent traffic disruptions during this period.
Crews will also begin mobilizing into the area and start setting up a construction yard along the northern half of Terry A Francois Boulevard to stage construction trailers, materials, and equipment. This mobilization work is anticipated to begin the week of September 17, 2018. The block of Terry A Francois Blvd., between Third Street and the north east corner will be closed to through traffic for the duration of rehabilitation work. Access will be maintained for emergency vehicles, bicycles, and pedestrians, as well as “The Yard” and outdoor seating on the south side of the street.
The Third Street Bridge will operate normally and be available for lifts to maritime traffic until September 17, 2018. After September 17, 2018, the bridge will be lowered and locked in the down position and will not be available for any requested bridge lifts until completion of the project in late 2019.
Actual rehabilitation work on the bridge will commence on approximately October 1, 2018, starting with installation of containment scaffolding, pending favorable traffic and tide conditions. The contractor will implement traffic control plans as needed to redirect vehicles, bicycles, and pedestrians to safely perform the work.
At this time, the contractor does not anticipate a need for full bridge closuresuntil summer 2019, though certain rehabilitation activities may require periodic short term full bridge closures. Wherever possible, the Contractor and San Francisco Public Works will reach out and provide early notification about the timing and duration of such closures.
During rehabilitation work, access across the bridge will be maintained for vehicle, bicycle and pedestrian traffic, except for instances where temporary full bridge closures are required. Please be aware that travel lanes may be reduced, restricted, or altered as needed during different phases of rehabilitation work on the bridge.
Detailed project information about the phasing and sequencing of upcoming work and updated traffic routing plans will be posted on the web page and shared with the public as we get closer to the start of construction.
Thank you for your patience and understanding as we prepare to begin rehabilitation of this vital and historic San Francisco landmark.
