Colfax & Federal Interchange Transformation Project

Both the City and County of Denver (CCD) and the Colorado Department of Transportation (CDOT) recognize the opportunity at the Colfax and Federal Interchange to reevaluate the current configuration and develop a design that maximizes network opportunities and future land use efficiency.


The purpose of the City and County of Denver Colfax and Federal Interchange Transformation Project (“Transformation Project”) is to build out the understanding of technical factors, including the interchange configuration, improving the transportation network for all users, stormwater requirements and possibilities, and evaluate the scenarios that best connect to the vision, goals, recommendations and strategies from previous citywide and area specific plans.

With over 25 background documents and points of reference that include historic information, neighborhood plans, master plans, roadway alignment studies, and hydrology studies, there are many commonalities that the Transformation Project will build upon.  These previous efforts had many commonalities that include the need for equitable, affordable and inclusive places/spaces; improving safety for a multi-modal transportation system; and supporting community values that include diversity and supporting the existing community.
