Project Description

The proposed project would replace the existing bridge over San Geronimo Creek with a new structure accommodating one 12-foot-wide lane with 2-foot-wide shoulders and bridge railings, resulting in a bridge width of approximately 20 feet. The new structure would be a 70-foot-long, single-span, precast, prestressed concrete slab unit bridge. The alignment would shift to the east by approximately 7 feet. The roadway profile of the bridge would be raised approximately 4 feet to clear the 100‑year flood elevation. The project improvements would remain within California Department of Transportation (Caltrans) and Marin County’s right-of-way (ROW), and permanent ROW acquisitions are not anticipated.
