Metro Denver Critical Culvert Rehabilitation
About the Project
Work will occur in various locations. The first phase will occur along US 40 from Mile Point 243 to MP 251 on Berthoud Pass. Crews will then move to CO 74 from MP 3 to MP 5 in Evergreen, along with US 40 at MP 274 in Genesee. The following phase will be on CO 103 from MP 2 to MP 9 in Idaho Springs. The project will primarily consist of installing UV CIPP into existing storm sewer culverts to rehabilitate the pipes.
