There are three anticipated vehicular traffic closures of the bridge. All attempts will be made to maintain pedestrian and bike traffic at all times. Ongoing coordination with emergency services will ensure emergency vehicle traffic is adequately accommodated.
- One week closure for delivery and installation of precast girders in Phase I
- One week closure for delivery and installation of precast girders in Phase II
- One week closure for concrete pour between upstream and downstream halves of new bridge
A minimum of one month notice will be provided when these closures are scheduled.
Two strategic traffic shifts will be conducted so that phased construction can occur. First, vehicles will be moved to the downstream side of the bridge so that the existing upstream portion can be demolished and its replacement built. When the upstream portion is complete, traffic will be shifted onto the completed bridge so that the existing downstream portion can be demolished and rebuilt. When the downstream half is complete, the bridge will reopen to full traffic.
There will be periodic one-way traffic control on the bridge. Delays of maximum 5 minutes are expected during these times. Every effort will be taken to minimize inconvenience to bridge users, including carefully orchestrated traffic management with on-site signage and flaggers.
The project team will ensure that motorists, bicyclists, and pedestrians continue to have safe access to the bridge throughout construction. The start of Phase I work will close the bike lane and walkway on the upstream side of the bridge. Bicycle and pedestrian traffic will be consolidated on the downstream side of the bridge. When traffic is shifted onto the completed upstream portion, there will be no delineated bike lanes but one extra-wide multi-use path.
There will be periodic pedestrian and bicycle traffic control for safety and utility requirements.
Traffic control shall be managed on the waterway for safety. Waterway traffic will be monitored and controlled during certain operations, such as lifting loads over the waterway, to provide for the safety of any waterway users.
- Monday – Friday, 7:30 a.m. to 6:00 p.m.
- Saturday, 8:30 a.m. to 6:00 p.m.
No, parking for construction workers will be provided in the temporary staging area on Bon Air Road.
The construction cost of this project is estimated at approximately $16 million. Approximately 89% of the funding will come from the federal Highway Bridge Replacement and Rehabilitation (HBRR) Program, administered through Caltrans. Utilities will pay for all utility relocations, and the balance will come from the City Bridge Fund.
