About the Project:

The Colorado Department of Transportation is moving quickly to put stimulus funding to work in southeastern Colorado. Along with contractor partner Kraemer North America, CDOT will begin work on June 24 to improve the safety and accessibility of Powers Boulevard/Colorado Highway 21 between Mile Points 149 and 151 at Research Parkway.

Work will consist of replacing the current at-grade intersection with an innovative Diverging Diamond Interchange and constructing an overpass for Powers Boulevard/ Colorado Highway 21 traffic to move continuously through the intersection over Research Parkway (pictured below). In addition to building the new Diverging Diamond Interchange structure, with Powers Boulevard going over Research Parkway, the project will include new pavement to three miles of CO 21 and add pedestrian/bicycle enhancements to improve access to schools in the area. The project is in response to the growth in the northeastern area of Colorado Springs along the Powers Boulevard corridor and is part of CDOT’s on-going effort to improve interchanges along the corridor.

Project Benefits:

The new Diverging Diamond Interchange will increase the flow of traffic by allowing free-flowing turns when entering and exiting Powers Boulevard/Colorado Highway 21 from Research Parkway by eliminating left turns against oncoming traffic and reducing the number of traffic signals.
