CO 9 Surface Treatment in Summit and Grand County

Project Complete!

SUMMIT AND GRAND COUNTY — The Colorado Department of Transportation has completed a surface treatment project at two locations CO Highway 9 as of October 2023. Elam Construction of Grand Junction was the contractor for this project.

Work on CO 9 from MP 107 to MP 113, north of Silverthorne,  consisted of 1.5” hot mix asphalt overlay, guardrail upgrades, repair of grooved slopes, striping, signing and shouldering. Work on CO 9 from MP 126 to MP 137, south of Kremmling, consisted of a full width chip seal and fog coat, minor shouldering, striping, repair of grooved slopes, installation of riprap and signing.

Project Benefits

  • The HMA added approximately 10 years of life to the highway, provided a smoother road surface and added durability by increasing the resistance of ruts and road damage. This will allow for a smoother and safer drive for motorists.
  • The chip seal application will help protect and extend the life of the underlying pavement. The new surface will provide skid resistance and reduce overall cracking.
  • Other benefits of the project include installation of new guardrail that will be 31 inches high, designed to meet new safety standard requirements. The higher railing will help veering vehicles remain on the road more effectively, making the highway safer for the traveling public. The former standard height of guardrail was 27 inches.
