I-76 Corridor Improvements Between Iliff & Crook Interchanges

About the Project:

The Colorado Department of Transportation will begin a concrete panel replacement and diamond grinding project on I-76 from the Crook interchange/EXIT 149 to two miles west of the Iliff interchange/EXIT 134. The initial phase will begin constructing two crossover detours and six interchange on/off ramp detour crossings to accommodate traffic. Work will consist of concrete panel replacement, sawing and sealing, and diamond grinding. After finishing each segment, construction will progress west.

The remaining westbound work will continue after winter shutdown beginning in May 2025. The concrete sawing, sealing, and final pavement markings will be completed. At the same time, operations will begin on the eastbound lanes following the same process.

Other improvements include new sign replacement, final striping, and guardrail upgrades.

Project Benefits

  • Concrete panels that are cracked, broken and not seated properly will be replaced to mitigate further deterioration of the road.
  • Diamond grinding the roadway will take place to improve the smoothness and surface texture of concrete pavements. This method involves the use of diamond saw blades to grind the surface of the pavement, removing irregularities, bumps, and imperfections resulting in a much smoother ride for vehicles.
  • Installation of new signs and final striping will improved safety, efficiency, and communication for motorists.
  • Guardrails will be upgraded to prevent vehicles from leaving the roadway, reducing the severity of crashes and minimizing the risk of injuries or fatalities.

Work Schedule:

  • Daytime work hours are from 7 a.m. to 5 p.m., Monday through Friday
  • Nighttime work hours may occur from 9 p.m. to 5 a.m.

Traffic Impacts:

Motorists can expect the following impacts during the period of construction:

  • Multiple median cross-overs will be constructed throughout this corridor to accommodate traffic
  • 11’ width restriction will be in place when the lane closures are in effect
  • Speed limit of 55 MPH through the construction zone
  • Construction trucks entering and exiting the work zone
