I-25 Culvert Repairs Trinidad
Project Facts
- Cost: $613,000
- Contractor: American West Construction, LLC.
- Timeline: March to May 2020
- Location: Various highways in Las Animas and Huerfano Counties
Project Overview
In March 2020, crews will begin the repair and rehabilitation of 6 separate culverts at 6 separate locations.
The culverts will be rehabilitated using several methods that vary from site to site. Sites 1 and 6 will be repaired by use of spin casting (CCCP), which uses centrifugal force to uniformly line the inside of each pipe with a high strength mortar. This method of rehabilitation eliminates the need to dig up the road in order to replace the culvert, thus reducing the cost and impact to the traveling public.
The goal of the project is to increase the longevity of each storm water conveyance pipe to prevent failures and erosion of the embankment(s), while ensuring the safety of the travelling public.
The project locations are:
- Huerfano County Site 1 – I-25 northbound at mile point (MP) 49.32 and Industrial Park Dr.
- Las Animas County Site 2 – I-25 southbound at MP 24.1
- Las Animas County Site 3 – I-25 southbound at MP 23.4
- Las Animas County Site 4 – I-25 southbound at MP 20.9
- Las Animas County Site 5 – I-25 southbound at MP 20.5
- Las Animas County Site 6 – US Hwy 350 and County Rd 83 westbound
Construction will begin at Site 6, on US 350 off of ROW eastbound, 50 feet south of County Road 83. Sites 2-5 will be repaired by removing existing sediment and replacing existing culvert pipe and end sections.
This culvert repair project will consist of:
- sediment removal
- grout filling voids in pipe
- using a spincast technique to repair 115 LF of a 48" culvert with a mortar compound
- removal and replacement of 20 LF of a 24" culvert pipe.
Proposed Work Schedule
- The work is scheduled to take place over 2 months from March 10th to May 6th.
