Project Description
First steps
Why we needed an Environmental Assessment
What we investigated

In accordance with the Federal Highway Administration (FHWA), the Colorado Department of Transportation (CDOT), through its consultant team of Wilson & Company and PBS&J, initiated the C-470 Corridor Project.The project consisted of an Environmental Assessment (EA) along the southern reach of the Corridor and an Express Lanes Feasibility Study (ELFS) from South I-25 to West I-70. The completed EA identifies the future needs, then examines improvements that meet those needs, including the number of travel lanes, interchange modifications and other major capacity improvements, as well as alternative modes of transportation. The EA has taken approximately three years to complete. See Schedule

The Express Lanes Feasibility Study (ELFS) examined the feasibility of tolled express lanes to address congestion along the corridor from South I-25 to West I-70. The study results were incorporated into the EA as one of the examined alternatives.

The Corridor is bordered by three counties (Arapahoe, Douglas, and Jefferson) and seven cities (Centennial, Greenwood Village, Golden, Lakewood, Littleton, Lone Tree and Morrison.)

Public input is a critical component of the project. Please contact us with your issues or concerns.
