CDOT to begin Rockfall Mitigation Project on US 6/Clear Creek Canyon

February 13, 2018 - Denver Metro Colorado/CDOT Region 1 - Speed limits to be strictly enforced

JEFFERSON/CLEAR CREEK COUNTIES- Starting February 20, 2018, the Colorado Department of Transportation and contractor partner Apex Rockfall Mitigation will begin rockfall mitigation work on US 6/Clear Creek Canyon between Colorado Highway (CO) 93/CO 58 and CO 119 from mile points 260 to 272 in Jefferson and Clear Creek Counties.
This $3 million project will include rock-scaling, removal of scaled rock, installation of rock reinforcement, rock anchors, mesh anchors, and 285,000 square feet of wire mesh. This project is necessary to protect the safety of motorists and to prevent road damage or unexpected closures that could be caused by a natural rockslide.
In order to protect the safety of crews working on the project and the traveling public, daytime full closures of US 6/Clear Creek Canyon between CO 93/CO 58 and CO 119 must be conducted as rockfall mitigation cannot be done at night.
“This area of US 6/Clear Creek Canyon is particularly prone to rockslides,” said Paul Jesaitis, Region 1 transportation director. “We’re excited to start this project that will improve the safety of those traveling through the canyon and will help prevent rockslides that can sometimes close roadways for weeks on end. We know the daytime full closures will be inconvenient and would like to thank the public in advance for their patience.”
The project is scheduled to begin in late February and will continue through the end of April 2017 with a summer shutdown from May to November 2018. The project will resume November 1with an anticipated completion date of spring 2019.
Motorists can expect daytime full closures of eastbound and westbound US 6/Clear Creek Canyon, Monday through Thursday, with work hours as follows:
·        Monday through Wednesday10 a.m. to 5 p.m.
·        Thursday6 a.m. to 5 p.m.
During this time, there will be no parking or access for recreation use. Motorists can use I-70 as an alternate route during construction hours.
