Transportation Studies

C-470 Corridor Project

In accordance with the Federal Highway Administration (FHWA), the Colorado Department of Transportation (CDOT), through its consultant team of Wilson & Company and PBS&J, has initiated the C-470 Corridor Project. The project consists 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 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.

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. Visit the project website for updates on the progress of the study. For more information, please contact Wilson & Company, Inc. at 303-297-2976 or email.
