Title

Creston Road Bridge over Quail Creek Replacement Project, 300714/ ED24-106

Description

The County of San Luis Obispo (County) Public Works Department, with funding from the Federal Highway Administration (FHWA) and oversight by the California Department of Transportation (Caltrans), proposes to replace the existing, structurally deficient Creston Road over Quail Creek Bridge (RD-4067-BR1). The Creston Road Bridge over Quail Creek Replacement Project (project) is located on Creston Road approximately three miles southeast of the City of Paso Robles. The purpose of this project is to permanently repair the bridge which was damaged during January 2023 storm events and temporarily repaired to preserve public access. The project footprint consists of an approximate 4.05-acre area and contains the right-of-way for the proposed project, all areas of ground disturbance, and potential staging areas. Staging is proposed on Creston Road, within County right-of-way, and within adjacent fields that have been previously disturbed by grading and would not require improvements (e.g., grading, leveling). The existing single-span bridge is 20 feet long and 23 feet wide. The new bridge would be a 75-foot-long, 38 feet wide, single-span, precast, prestressed voided slabs supported on seat type abutments founded on a pile cap and driven steel HP piles. The increased width is proposed to accommodate two 11 foot-wide travel lanes, two 6-foot-wide shoulders, and concrete post and beam rails, which would improve safety for agricultural equipment that uses the bridge. The existing bridge would be demolished and a temporary construction detour would be required.
