I-70 Floyd Hill Project Update

Happy Holidays! There are no scheduled traffic impacts along eastbound and westbound I-70 for the I-70 Floyd Hill Project from 6 a.m. Saturday, Dec. 23 until 6 a.m., Monday, Jan. 8. Watch for the next project update in your email inbox on Friday, Jan. 5. Use COtrip.org to plan your trip! 

Note: The next rock blast/traffic hold is expected in late January/early February.

Clear Creek Greenway Trail Closure

The Clear Creek Greenway trail remains closed between the US 6 (Exit 244) and Hidden Valley (Exit 243) interchanges for construction and utility work in this area. This work is scheduled to last until spring 2024, but trail users can expect ongoing trail impacts and closures through 2026. This portion of the trail will be an active construction zone and will be unsafe for multi-use travel. Other segments of the trail will remain open. 

There is currently no alternative route for this trail closure. The Project is actively working on solutions for alternative trail access through 2026. Please plan ahead and continue to check this webpage prior to Clear Creek Greenway Trail use. For up-to-date information visit bit.ly/ccgreenway.

Early Project Holiday Hours 

There will be no scheduled traffic impacts for the US 40 & Floyd Hill Roundabouts project for the holidays from 6 a.m., Saturday, Dec. 23, until 6 a.m., Monday, Jan. 2.

I-70 Floyd Hill Deconstructed: Behind the Scenes Construction Videos

The I-70 Floyd Hill Project recently launched a new video series called I-70 Floyd Hill Deconstructed, which provides an inside look at the various construction activities required to build a project of this magnitude. Click on the links below to watch each video: 

• Retaining walls and creating a matching mountain aesthetic 

• Winter construction and driving

I-70 Mountain Corridor-Wide Traffic Impacts 

• Reduced speed limits as low as 45 MPH, narrower lanes and shoulders, and increased truck traffic entering and exiting the work zones. Heed the speed limit, do not follow trucks into the work zone, go slow for the cone zone and do not drive distracted. 
• All construction activities are weather-dependent and subject to change. For real-time travel information, visit COTrip.org.

About the 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.
