CO 9 Surface Treatment in Summit and Grand County

About the Project:

SUMMIT AND GRAND COUNTY — The Colorado Department of Transportation will begin a surface treatment project at two locations CO Highway 9 beginning May 1. Motorists should plan for 20-minute delays during construction hours. Elam Construction of Grand Junction is the contractor for this project.

Work on CO 9 from MP 107 to MP 113, north of Silverthorne, will consist 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, will consist 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 will add approximately 10 years of life to the highway, provide a smoother road surface and will add 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.

Work Schedule:

Different from the traffic impacts, this should be the general working hours and schedule of the project. Example:

  • Work will last for 360 working days or approximately 18 months
  • Working hours are 30 minutes after sunrise to 30 minutes before sunset, Monday to Friday
  • Some overnight and weekend work is expected

Traffic Impacts:

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

  • Motorists should plan for one-lane alternating traffic guided by a pilot car and 20-minute delays.
  • Bicycles will be shuttled through the work zone. Hours of operation are Monday through Friday 7:00 a.m. to 5:30 p.m. The project is expected to be completed mid-Oct.
  • During chip seal and paving operations bicyclists will be shuttled through the work zone. Please go to the flagging station, place bike in the back of the truck and ride in the cab of the truck. Five cyclists can be shuttled through the work zone at a time.
  • Reduced speeds through chip seal area. This will help to prevent windshields from getting cracked.
