Milestone completed for I-70 Glenwood Canyon improvements in Colorado

June 24, 2020

The project is scheduled to be complete in October 2020

Crews with the Colorado DOT (CDOT) have completed an important project milestone on the I-70 Glenwood Canyon Surface Improvements project.

CDOT and contractor American Civil Constructors West Coast reopened the westbound on-ramp from the Grizzly Creek Rest Area to I-70 on Friday, June 19.

“The project team is excited to be at this point in construction where we can further reduce traffic impacts, particularly for our recreational community visiting Shoshone and Grizzly Creek,” CDOT Project Engineer Josh Cullen said in a statement. “The timing and phasing of this project was designed to accomplish work as efficiently and as early as possible. We are very grateful for everyone’s patience so far and look forward to completing the next steps to deliver these important infrastructure improvements.”

This eight-month improvement project includes resurfacing I-70 with a placement of thin bonded polyester concrete overlay, replacement of bridge joints and bearings, new pavement markings, and ADA ramp improvements at rest areas. Construction will occur within approximately 6.2 miles on I-70 in the Glenwood Canyon, between Mile Point (MP) 117.6 to MP 125. The project is scheduled to be complete in October 2020.

Polyester concrete overlay is the primary construction activity for this project. Upgrading this section of roadway will minimize the need for annual repairs as this road surface application is more durable and has a significantly longer lifespan than asphalt. This project will provide an improved driving surface and help ensure the longevity and safety of the state's infrastructure.

The milestone progress marks the completion of deck repairs and paving of the westbound deck at Hanging Lake and between Grizzly Creek and No Name. Crews have also completed improvements of ADA ramps at the canyon rest areas.
