I-70 Floyd Hill Project Update

There are no scheduled traffic impacts along eastbound and westbound I-70 next week for the I-70 Floyd Hill Project. Use COtrip.org to plan your trip!

Early Project Updates 

Westbound I-70 between Genesee (Exit 254) and Mile Point 255 - Expect a daytime single, left lane closure from 10 a.m. to 3 p.m., Monday, Feb. 26, through Thursday, Feb. 29, for dirt hauling. To learn more about the Genesee Wildlife Crossing project, visit the project website here.

US 40 east of County Road 65 - Expect a full closure of US 40 east of County Road 65 from 7 a.m., Monday Feb. 26, through 5 p.m., Friday, March 8. The closure will not impact the I-70 and CR 65 (Exit 248) interchange. This closure is necessary for crews to install curb, gutter and guardrail, remove asphalt, and pave the detour and roadway for the roundabout at US 40 and CR 65. Motorists should detour using I-70.

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 spring 2027. This one-mile 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.

I-70 Floyd Hill Deconstructed: Year-End Review

The I-70 Floyd Hill Project recently launched a new video series called “I-70 Floyd Hill Deconstructed.” This video series provides an inside look at the various construction activities required to build a project of this magnitude and meet the people who make it possible. 

Check out episode three, which takes a look at everything the project has accomplished since construction began in July 2023.

• Retaining walls and creating a match 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.
