Moore Street - Russian River Bridge Seismic Retrofit Project
Document Type
MND - Mitigated Negative Declaration

Document Description
The proposed project includes seismic retrofits of the Moore Street Bridge over the West Fork Russian River in Mendocino County. Proposed seismic improvements will include installation of shear keys and catcher blocks at each pier. In addition, large diameter Cast-In-Drilled-Hole (CIDH) piles will be placed behind both abutments to absorb a portion of the longitudinal seismic forces. The project will also include pavement rehabilitation of the approach roadways on both sides of the bridge. This work will include removal of the existing pavement, replacement of any failed roadway base areas, and placement of new hot mix asphalt pavement. Along with the seismic retrofit work, the proposed project will also include placement of Rock Slope Protection around Piers 2 and 3 as a scour countermeasure.
