Highway Closures and Impacts


 I-70 Floyd Hill Project

The I-70 Floyd Hill Project will improve eight miles of the I-70 mountain corridor, from west of Evergreen to eastern Idaho Springs. The Project will deliver a third westbound I-70 travel lane, which will function as an Express Lane, to improve the current two-lane bottleneck. Other major elements include constructing a missing two-mile section of the frontage road between Evergreen and Idaho Springs, building an eastbound I-70 extended on-ramp for slow-moving vehicles, improving traffic flow and access at interchanges and intersections within the project limits, improving sight distance on roadway curves, improving the Clear Creek Greenway trail, and implementing environmental mitigation to create safer wildlife movements and improve air and water quality, stream conditions and recreation.

Construction began in July 2023 and is expected to conclude in late 2028.

Update: The West Section traffic switch has been rescheduled due to weather. Motorists can expect eastbound and westbound I-70 traffic to shift toward the outside shoulders in April so crews can work in the median. Stay tuned for information on when this traffic shift will happen.

Peaks to Plains Trail Highway 6 Impacts

Construction of the Peaks to Plains Huntsman Segment through Clear Creek Canyon is progressing well.

As we prepare for the upcoming 2024 closures of US 6, the project team will distribute emails, update the project hotline, and post information on social media channels. These dissemination efforts will occur at least one week prior to the first closure.

As part of this effort, an updated factsheet will be developed outlining the specific dates and times for the upcoming month, also listed below*.

  • Monday April 8, 2024, 7:00pm to 7:00am
  • Monday April 15, 2024, 7:00pm to 7:00am
  • Monday April 22, 2024, 7:00pm to 7:00am
  • Monday April 29, 2024, 7:00pm to 7:00am

*All dates and times are weather dependent and if work is cancelled on a Monday, it may be postponed to the following Tuesday. 
*If needed, all full closures will be made passable for first responders.
