CO 318 Browns Park culvert replacement begins May 4

Project Announcement

April 28, 2026 - Northwestern Colorado - The work is expected to conclude in October with minimal impacts to motorists

Moffat County — The Colorado Department of Transportation, along with its contracting partner, Myers & Sons Construction, will begin a culvert replacement project May 4 on Colorado Highway 318 at Mile Point 1.25, located just east of the border with Utah. The work is expected to conclude in October with minimal impacts to motorists.

This project involves replacing the culvert on CO 318 near the Browns Park National Wildlife Refuge in Northwestern Colorado. The work will include removing the existing corrugated metal pipe culvert and installing a new concrete box culvert.

Culverts are vital infrastructure components that allow water to flow under the road, preventing flooding, erosion, and structural damage to the roadway above. Box culverts, such as the one that will be installed at this location, can handle greater volumes of water than pipe culverts.

Work Schedule:

  • Work is scheduled to begin May 4 and will be completed by early October.

Traffic impacts will include:

  • Normal working hours Monday through Friday 7 a.m. to 7 p.m.
  • Motorists can expect alternating traffic with brief delays
  • Traffic signals will be used while work is in progress
  • The speed limit will be reduced through the work zone
  • Wide loads will be restricted to 12 feet
