I-70 Paving through Ten Mile Canyon begins Monday

September 24, 2019 - Northwestern Colorado - Expect lane closures and traffic delays through late October

SUMMIT COUNTY  The Colorado Department of Transportation begins milling and repaving five miles of eastbound and westbound Interstate 70 between Officers Gulch and Frisco next week.

Initial work takes place on eastbound I-70 from 6 a.m. to 11 a.m. on Monday, Sept. 30. Then, beginning on Tuesday, Oct. 1, work hours will be extended from 6 a.m. to 8 p.m., Monday through Thursday, and from 6 a.m. to noon on Fridays.   Work continues for approximately one week on eastbound I-70 and then shifts to westbound I-70 for about another week.  During project hours, motorists can expect: 

  • Only one lane open to traffic, with a mobile one-mile closure in place
  • Possible slowdowns and delays
  • A reduced speed limit to help maintain safety through the work zone

Following paving operations, crews then will install final striping and rumble strips.  Project completion is scheduled for late October, weather permitting.

The $5.6 million project is contracted to APC Southern Construction of Penrose, Colo.

Work began in late June with guardrail replacement to bring it up to current standard and minor bridge rail repairs.  The upcoming new pavement will improve the highway’s durability and create a smoother surface.  The project also included resurfacing a portion of Main Street in Frisco and replacing two ADA ramps at intersections with Main Street.  All of the project’s improvements are part of CDOT’s Whole System-Whole Safety initiative.



The following tips are to help you stay safe while traveling through maintenance and construction work zones.

  • Do not speed in work zones. Obey the posted speed limits.
  • Stay Alert! Expect the unexpected.
  • Watch for workers. Drive with caution.
  • Don't change lanes unnecessarily.
  • Avoid using mobile devices such as phones while driving in work zones.
  • Turn on headlights so that workers and other drivers can see you.
  • Be especially alert at night while driving in work zones.
  • Expect delays, especially during peak travel times.
  • Allow ample space between you and the car in front of you.
  • Anticipate lane shifts and merge when directed to do so.
  • Be patient!  



To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This project takes a systematic statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.
