Diddy Roost Culverts Project on State Route 299

scheduled

The Diddy Roost Culverts project in Shasta County is on State Route (SR) 299 at various locations, from 0.5 mile west of Seamans Gulch Road to 0.1 mile west of Fenders Ferry Road. The purpose of the project is to replace existing deficient (fair and poor condition) culvert systems to meet current and future drainage needs and restore the integrity of the highway. Additionally, the project will add new traversable drainage inlets to improve the clear recovery zone. This project includes replacing 26 culvert systems and upgrading 20 drainage inlets along SR 299 in Shasta County. Most of the culverts in this project will be replaced by cut and cover, with the exception of systems under a significant amount of fill that cannot be replaced with a shallower pipe and downdrain. In such cases, the culverts will be replaced by trenchless methods.
