Gilman Springs Road Bridge

Project Overview

PROJECT OVERVIEW

The County of Riverside Transportation Department, in cooperation with the California Department of Transportation (Caltrans), is proposing to replace the existing Gilman Springs Road Bridge over Potrero Creek (Bridge Number 56C-0523) (Project). The Project is programmed as part of the Highway Bridge Program (HBP). The Project proposes to replace the existing two-lane bridge along Gilman Springs over Potrero Creek with a new two-lane bridge. The new bridge would be located slightly southwest of the existing two-lane bridge alignment. Along with replacing the aging bridge to mitigate scour issues, the Project would realign the roadway to improve sight distance and permit an increase in the speed limit and, hence, improve traffic flow.

ADDITIONAL PROJECT DETAILS

Project Location: The Project is located approximately 0.5 mile southeast of the State Route (SR) 79/Gilman Springs Road Interchange in unincorporated Riverside County, north of the city of San Jacinto. The existing bridge carries Gilman Springs Road over Potrero Creek near the base of Massacre Canyon.

Length: Approximately 0.16 miles

District: 5

Community:  Gilman Hot Springs
