US 6 Clear Creek Canyon Rockfall Mitigation

Work this week:  Feb.  25 – March 1,  2019

  • Motorists can expect a FULL ROAD CLOSURE Monday through Wednesday from 10 am to 5 pm and Thursday from 6 am to 5 pm (weather permitting).  
  • Closure preparation and traffic control devices are present prior to the hours of operation.
  • The road remains open, and motorists are able to access the canyon, until the posted closure time.

Project Facts

  • Cost: $3 million
  • Contractor(s): Apex Rockfall Mitigation
  • Timeline: January 2019 - April 2019
  • Location: US 6 in Clear Creek Canyon from CO 93 to CO 119 (mile points 260.2 to 271.6)

On January 7, 2019, crews on this project will start rockfall mitigation on US Highway 6 in Clear Creek Canyon to protect motorists and reduce emergency closures when debris lands on the roadway.

Specific work will include:

  • rock scaling
  • mesh anchor special installation
  • draped wire mesh installation
  • rock reinforcement anchors.

Schedule & Traffic Impacts

  • Normal project hours are from 10 a.m. to 5 p.m. Mondays through Wednesdays, and from 6 a.m. to 5 p.m. on Thursdays through April 2019.
  • There will be no parking access for recreation use during construction.
  • Expect full daytime road closures on US 6 Clear Creek Canyon between CO 93/CO 58 and CO 119, from mile point (MP) 260 to MP 272 for rockfall mitigation.
  • Motorists will still have access at the west end of the canyon, US 6 & CO 119, to access Centennial Cone Park at the Mayhem Gulch Trailhead and the Peaks to Plains Trail at the Big Easy Trailhead.
  • Use I-70 as an alternate route during working hours and full road closures.

Background

Rockfalls happen regularly in Clear Creek Canyon, ultimately causing closures, accidents, and roadway deterioration. This project aims to address these issues and reduce the overall impact of rockfalls in the canyon.

Before the 2018 summer shutdown of this project, crews removed roughly 35,000 tons of rock, and installed around 125,000 square feet of wire mesh and 125 mesh anchors.
