I-25 Concrete Panel Replacement from Fort Collins to Owl Canyon Road

About the Project:

In early October, The Colorado Department of Transportation will begin a concrete panel replacement and diamond grinding project on the northbound lanes of I-25 near Fort Collins.

The initial phase will begin with diamond grinding the concrete on northbound I-25 just north of the Colorado Highway 14 exit. Construction will include single-lane closures of up to 1.5 miles in length. After finishing each segment, construction will progress north to the next 1.5-mile section. The concrete panel replacement on the northbound side is to be performed concurrent with the diamond grinding operation.
Phase two will begin in April 2024. This will finish out the remaining concrete sawing and sealing and final pavement markings on I-25 north. At the same time, work will begin on the southbound lanes on I-25 south where concrete panels will be replaced, followed by diamond grinding and concrete sawing and sealing. The full project repairs with diamond grinding and sawing and sealing will be from CO 14 in Fort Collins to Owl Canyon Road in Wellington.

Project Benefits

  • Diamond grinding will smooth the roadway by taking out the bumps or pavement variability, whether it is due to settling or cracking. A smoother ride is a better driver experience and it also lessens the damage to the road from bouncing vehicles.
  • Concrete panels that are cracked, broken, and not seated properly will be replaced to mitigate further deterioration of the road.

Work Schedule:

  • The project begins in early October and will be completed in August 2024.
  • Daytime work hours are from 7 a.m. to 5 p.m., Monday through Friday.

Traffic Impacts:

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

  • Single lane closures will be 24 hours a day, beginning each Monday at 7 a.m. to Friday 5 p.m. There will be no lane closures on the weekends.
  • Nighttime work hours may occur from 9 p.m. to 5 a.m.
  • 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.
  • Refer to COtrip.org for real-time travel conditions and road closures
