Cimarron interchange

The second largest transportation project in Colorado Springs’ history, the Interstate-25/Cimarron project, will break ground Wednesday, signaling the official start of a new “gateway” to downtown Colorado Springs and to the mountain communities to the west.

Before the ground-breaking, the Colorado Department of Transportation (CDOT) will host an open house today, Tuesday, May 26, regarding the project.

CDOT will deliver construction details and schedule, and the public may view designs of how the interchange will look when finished. Plans call for a high-functioning interchange that safely handles more vehicles and enhances multi-modal travel for those using the I-25/ Cimarron interchange and the trail system along the creeks.

Today’s open house will be held on from 5-7 p.m. at City Auditorium, 221 E. Kiowa St. A short, formal presentation begins at 5:30 p.m., followed by an informal open house with information stations and an opportunity for the public to meet and ask questions of the project team. 

Wednesday’s ground-breaking will take place from 10 a.m.-noon at America the Beautiful Park, just west of the pavilion.

Planned improvements include reconstructing I-25 between Colorado Avenue (to the north) and the Nevada Avenue/Tejon Street interchange (to the south), and include a continuous northbound travel lane between the south Nevada/Tejon interchange and the Cimarron interchange. Project boundaries on Cimarron are between Eighth Street to the west and the Cimarron bridge over Fountain Creek to the east. 

Once construction is complete in 2017, the project will provide:

  • Improved interstate and interchange operations and safety;
  • Improved highway alignment and improved ramps, acceleration/deceleration lanes for increased vehicle storage and safety;
  • New I-25 bridge structures;
  • New connection between 8th Street and Cimarron Street; and
  • Improved trail connectivity and aesthetic treatments.

At the open house, information stations will cover these topics:

  • Project overview and schedule milestones;
  • Project aesthetics;
  • Traffic management;
  • Park/trail/stream improvements; and
  • New connection between Cimarron and Eighth streets.

“When complete, this will be a high-functioning interchange that safely handles more vehicles and enhances multi-modal travel for those using I-25, U.S. 24/Cimarron Street and the trail system along Monument and Fountain creeks,” said CDOT Resident Engineer Dave Watt.

“The open house is an opportunity for the public to review construction details, project schedule and traffic management,” added Watt. “It’ll also provide a chance for a review of the planned aesthetic enhancements and to give us feedback regarding possible detours during the work planned along the trails and creek connections.”
