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 2028.
