CAL 4 Culvert Replacement
Project Description
The California Department of Transportation (Caltrans) proposes to replace 22 culverts that have exceeded their design life expectancy along State Route 4 and State Route 49 in Calaveras and Tuolumne Counties, respectively. The proposed culvert restoration methods include replacing the deteriorated culverts with reinforced concrete pipe, installing inlet and outlet end treatments consisting of flared end sections, and installing concrete headwalls, concrete wing walls, and rock slope protection. The work will include excavating existing culverts, jacking and boring for deeper culverts, backfilling, concrete casing, paving, installing rock slope protection at outlets, repairing or replacing headwalls, and re-striping. Temporary construction easements and permanent right-of-way easements are expected at locations for construction and maintenance activities.
Project Benefits
Purpose
The purpose of this project is to improve the drainage systems to prevent flooding of the roadways, reduce culvert failures to prevent erosion of the soil below the pavement, and extend its service life.
Need
The project is needed to address the deteriorated culverts caused by overuse and/or culverts that are past their design life.
Funding Source
Project is anticipated to be programmed in the 2020 State Highway Operation and Protection Program (SHOPP) program for delivery in FY 2023/24 with SB-1 Funding.
