Repair of 12 Culverts using CIPP along I-8 in Imperial County

Caltrans proposes to repair twelve (12) culverts using cured-in-place pipe (CIPP) lining in Imperial County on I-8 at various locations from 0.1 miles west of the Imperial Highway undercrossing to 0.6 miles west of the Meloland 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 (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. Access will occur on travelled way. There will be no permanent impact areas and no staging areas. Signs are limited to temporary construction area signs, which will be placed in the vicinity of the culvert work and will not be installed in paved nor unpaved areas. All work will occur within Caltrans state right-of-way.
