Document Description
Caltrans proposes to repair six (6) culverts using cured-in-place pipe (CIPP) lining on Interstate 15 in San Diego County at various locations from the University Avenue overcrossing to 1.3 miles south of the Miramar Way 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 CIPP 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. No construction equipment will be utilized on CIPP projects, and no grading will be performed. All work will occur within Caltrans state right-of-way.
