Document Description
The purpose of this project is to clean, paint, and prevent future damage to Briones Valley Road Bridge (Bridge No. 28C0495). The project is needed to remove rust from the bridge as well as preserve the structural condition and remaining service life of the bridge. The maintenance-preventative work will consist of implementing a lead compliance plan and work area monitoring program if needed, blast cleaning, repainting superstructure steel members, applying corrosion inhibitor, and tightening or replacing missing steel bolt connections. Construction is anticipated to begin in Summer 2027. The project would occur approximately seven feet above the creek bed, therefore no erection of a working platform is anticipated. No ground disturbance or vegetation removal is anticipated. Real estate transactions may be necessary. The project is in the East Contra Costa County Habitat Conservation Plan (HCP) and will comply with HCP requirements. Work staging area(s) will be placed away from sensitive areas and appropriate Best Management Practices (BMPs) will be implemented to protect the creek.
