8 Culverts via CIPP off SR 52

Caltrans proposes to repair eight (8) culverts via CIPP (Cured-in-Place-Pipe Liner) In San Diego County on SR 52 at various locations from 0.1 miles east of the 805 and 52 separation to 0.2 miles west of the Santo Road overcrossing. This project will not require temporary construction easements, permits to enter, or permanent acquisitions. This project will include shoulder, lane, and/or ramp closures to allow sufficient space for the Contractor to access the culvert end treatment (aka drainage inlet, etc.). No detours are required for this project. CIPP liner involves inserting a flexible liner into the upstream culvert end treatment, which is then pulled through to the downstream culvert end treatment. The liner is then inflated and cured to harden the liner. Work adjacent to the culvert end treatments will be limited to workers on foot with hand tools only. Equipment will be parked on the paved area and is limited to a vactor truck to clean the culverts, CCTV/Cure truck for video and curing of culvert, and service truck for unrolling liner.
