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

About the Project:

Construction crews have resumed work on the concrete panel replacement and diamond grinding project on the northbound lanes of I-25 near Fort Collins.

This project will improve safety for the traveling public by replacing crumbling concrete panels and grinding the existing concrete pavement to take out the bumps that are due to settling in the roadway to create a smoother drive. The improvements will provide a smoother driver’s experience and help lessen the damage to the roadway. Concrete panels that are cracked, broken, and not seated properly will be replaced to mitigate further deterioration of the road.

Improvements include concrete panel removal and replacement, joint sealing to minimize the effects of surface water infiltration, full depth roadway repair in sections that are damaged beyond pothole filling, and pavement markings.

During the 2023 construction season, crews completed the concrete panel replacement on northbound I-25 concurrent with the diamond grinding operation.

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 2023 and will be completed in early December 2024
  • Daytime work hours are Monday through Friday, 7 a.m. to 5 p.m.
