Foresthill Road Bridge Seismic Retrofit and Paint Project

The Foresthill Road Bridge was placed on the Mandatory Seismic Retrofit list by Caltrans in 1999. The bridge is a 2,428 ft long, 75 ft wide steel deck truss structure which spans the North Fork of the American River. The project work scope includes, but is not limited to, the retrofit of the existing bridge, removal of the existing paint system, repainting of the bridge, installation of a new catwalk system to facilitate required inspections and maintenance of the bridge, and replacing the bridge railing.

The Foresthill Road Bridge Seismic Retrofit and Paint Project is anticipated to be one of the most costly and technically involved construction projects to date in Placer County.

As the prime consultant, NV5’s scope of work includes constructability review, pre-construction services, resident engineering, roadway/structures inspection, steel erection inspection, steel shop inspection, and labor compliance.

Project highlights include removal and replacement of existing structural steel elements and gusset plates; modification of abutment transverse shear walls; placement of abutment rock anchors; installation of bucking restrained braces; modification/replacement of transverse shear keys; installation of new steel stringers and concrete decking; replacement of the bridge rail; application of methacrylate to the existing bridge deck; construction of a new catwalk system; paint abatement; shop inspection of structural steel elements; coating removal and field priming operations; and finish paint operations.
