History and Prior Studies

Various city-wide, long-range studies such as Denver’s Comprehensive Plan adopted in 2000 and Blueprint Denver adopted in 2002 have been conducted over the past 10 years. These studies identify major transportation corridors such as South Broadway and make strategic recommendations to accommodate Denver’s future growth. These strategies are broken into three major categories:
  • Areas of Change and Areas of Stability - Identifying, managing and focusing direct growth to areas of change and preservation of the character in areas of stability
  • Multi-Modal Streets - Improving the functionality of streets as a means to move people; not just cars
  • Mixed-Use Development – Creating and supporting mixed-use development opportunities that offer and accommodate a variety of transportation options

These studies specifically designate the South Broadway Corridor as an area of change and in need of improvement. Consequently, the National Environmental Policy Act (NEPA) process was set in motion. A number of studies were conducted to analyze and specify improvements and resulting impacts necessary to meet future need, growth and development.

The South Broadway and I-25 System Level Study and Interstate Access Request (30MB pdf) prepared for the Colorado Department of Transportation was released and adopted by the Transportation Commission by resolution (TC-1583) in January 2008.  In March 2008, the South Broadway Environmental Assessment and Section 4 (f) Evaluation was approved and released and the following November, the South Broadway Finding of No Significant Impact (FONSI) was approved. 

These documents were the result of a lengthy study and an extensive public outreach process through which alternatives were developed, screened and evaluated, culminating in a thoroughly vetted recommendation for a Preferred Alternative. The planned improvements for South Broadway, Arizona to Exposition and I-25 Interchange project is a direct result of these studies, strategies and recommendations and will ensure this important corridor meets the area’s complex demands.
