All Harbor Bridge construction work is dependent on weather.
The project started in February 2021, and on Dec. 11, 2021, was suspended due to environmental regulations for in-creek work.
Work on the intersection improvements started in May 2022 while in-creek work resumed in June 2022 to complete the western portion of the new bridge and switch to the final traffic configuration. The deck of the western portion of the new bridge and the bridge approach slab have been completed. The project is expected to be completed in the fall of 2022.
Changeable message and directional signs will be in place to assist motorists traveling in the area. The California Highway Patrol (CHP) will be on-site during the closures.
Please drive with caution. Slow for the Cone Zone and Be Work Zone Alert. Caltrans thanks motorists for their patience while we work to maintain our state's highways, bridges, and tunnels.
