I-76 Corridor Improvements Between Iliff & Crook Interchanges

About the Project

The Colorado Department of Transportation and contracting partner Castle Rock Construction began a concrete panel replacement and diamond grinding project in July 2024 on Interstate 76, from the Crook Interchange to two miles west of the Iliff Interchange (Mile Point 150 to 132).  

The anticipated completion date is October 2025.

The initial phase of the project began at the Crook and Proctor Interchanges and involved constructing several crossover detours to facilitate head-to-head traffic. This configuration will ensure crew safety and minimize disruptions to traffic flow during construction.

Remaining work includes road resurfacing, bridge rehabilitation and upgrading guardrails and signage along this critical transportation route. These improvements will ensure a smoother, safer drive for motorists and extend the life of the highway.

Project Recap

Crews have completed significant roadway improvements along I-76 between the Crook Interchange and two miles west of the Iliff Interchange (Mile Point 150 to 132). The project included replacing concrete panels and performing diamond grinding to remove surface irregularities, bumps and imperfections. This process improved surface texture and results in a much smoother ride for motorists.

In addition to the completed concrete panel and grinding work, crews also performed resurfacing, bridge rehabilitation and upgrades to guardrails and signage along this vital corridor. Together, these improvements enhance safety, extend the service life of the roadway and create a smoother and more reliable travel experience for the public. The completed work not only improves day-to-day driving conditions but also provides safety along one of Colorado’s key east-to-west interstates.
