Resurfacing project on CO 9 and US 6 to begin this week in Dillon

April 24, 2017 - Northwestern Colorado/CDOT Region 3 - Safety benefits include new sidewalk ramps, drainage improvements and traffic detection systems

SUMMIT COUNTY/DILLON – The Colorado Department of Transportation (CDOT) and contractor APC Southern Construction Company are scheduled to start the Colorado Highway (CO) 9 and US 6 Repaving project this week. The project will span approximately 7.4 miles along CO 9 and US 6, along the corridor of I-70 in Dillon. Additional benefits to the work area include the installation of Americans with Disabilities Act (ADA) -compliant ramps and sidewalks, and storm water drainage improvements. A traffic detection system will also be implemented to improve the flow of traffic patterns along this stretch of roadway, decreasing wait times for motorists.

The established work zone on CO 9 will extend from Mile Points (MP) 101.6 to 107. The work zone on US 6 will be between MPs 208.7-210.7. The project is scheduled for completion by mid-October 2017.

"The Dillon and Silverthorne resurfacing project has been needed for some time due to deteriorating pavement condition over the years, as it was last paved in 2002,” says CDOT Resident Engineer Grant Anderson.  “The resurfacing will improve drainage and the overall ride, and safety will therefore be improved.”


The schedule for the six-month project include daytime working hours of 7:00 am – 5:00 pm, Monday through Thursday, and 7:00 am – 12:00 pm on Friday. Night work will be required when paving at the intersection of I-70 and CO 9, with the intent of lessening the impact on the traveling public. No work is expected on weekends or holidays.


Motorists can expect delays of up to 20 minutes during project working hours, and speed limits will be reduced. There will be alternating lane closures in both directions, and flaggers will be directing traffic along the construction zone.  Width restrictions of 12 feet will be in place for the duration of the project. Despite the ongoing sidewalk enhancements, pedestrian access will be maintained throughout the course of the project. Please pay close attention to posted detours. Flaggers will be on-site to guide pedestrians through the construction zone in certain situations.
