CAL 4 Culvert Replacement

project is currently in plans, specifications & estimates (ps&e) phase.

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.
