Prioritized Project Goals


Project goals were established and approved by the Executive Oversight Committee. The goals provide direction to the project team and to the design-build contractor team.


Project Goals 

1. Maximize overall safety, capacity and operation of the interchange and the surrounding transportation network within the Project budget;


2. Complete Project construction to be fully operational before December 1, 2017;


3. Minimize impacts and inconvenience to the community, motorists, businesses, downtown and the public during construction; and


4. Achieve an aesthetically pleasing design compatible with current and future amenities and enhancements in and around the interchange.


"The project goals were developed and prioritized by several community organizations in collaboration with the project team and were used to help establish the project contract requirements."

Long-Awaited Interchange Reconstruction Project Breaks Ground


Public Open House May 26


The second largest transportation project in Colorado Springs' history behind COSMIX breaks ground this month at the Interstate-25/Cimarron interchange. Ground breaking signals the official start of a new "gateway" interchange to downtown Colorado Springs and to the mountain communities to the west. The community is invited to come learn about the construction details and schedule and view designs of how the interchange will look upon completion. When complete, it will be 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. 


Tuesday, May 26, 2015 

5-7 p.m. (presentation at 5:30)
City Auditorium
221 E. Kiowa Street
Colorado Springs, CO 80903

On-street parking and surface lots available. City parking garages: 127 E. Kiowa or 130 S. Nevada.

A short, formal presentation will begin 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.

Information stations you can visit at your leisure will cover these topics:

  • Project overview and schedule milestones

  • Traffic management
  • Park/trail/stream improvements
  • New connection on Cimarron Street to 8th Street to alleviate congestion at the intersection. 

CDOT Selects Design-Build 

Contractor Team

The Colorado Department of Transportation (CDOT) announced the successful proposing team of Kraemer North America, LLC (Kraemer) and Tsiouvaras Simmons Holderness (TSH) to reconstruct the I-25/Cimarron Interchange project.


At just over $113 million, this will be the largest highway construction project in the Pikes Peak region since the reconstruction of I-25, known as COSMIX (Colorado Springs Metropolitan Expansion) was completed in 2008. More than 150,000 vehicles travel through the interchange daily, making it one of the region's busiest.   


Contractor team selection was a lengthy process in which three teams were shortlisted in May 2014. The shortlisted teams were then asked to provide proposals through the Request for Proposal (RFP) process. 


"All the proposals submitted were incredibly thorough, creative and exceeded the expectations of the established project goals," said CDOT Regional Transportation Director Karen Rowe. "In the end, and following a rigorous selection process, it came down to the team with the best technical proposal and the one providing the most improvement for the interchange and the surrounding transportation network. One team emerged as the frontrunner in this area because they provided the best value and response for meeting the project's goals."

Demolition Paves the Way for 

I-25/Cimarron Interchange 

Reconstruction Project


The view from Interstate-25 near the Cimarron Street exit has changed over the last couple of months with the demolition of several structures.The debris has been removed, holes are filled and the site has been leveled and graded for erosion control. 


Most recently, The Colorado Department of Transportation (CDOT) demolished approximately five structures in the northwest corner of the interchange, a few pole barns, sheds and two billboards immediately west of I-25 and north of the Cimarron Street exit ramp, allowing for the interchange reconstruction project this Spring/Summer.


"The owners/businesses were relocated after CDOT purchased the properties as part of the right-of-way acquisition process prior to the I-25/ Cimarron interchange reconstruction project," said Dave Watt, CDOT Project Director.

Demolition of the old Express Inn at the southwest corner of 

I-25/Cimarron interchange began in mid-

November in preparation for construction of the 8th Street cutoff. This area will also be used for material storage. Debris has been removed and final grading has been completed.


From left to right, CDOT Resident Engineer Dave Watt, CDOT Program Manager Doug Lollar, City Council Member Keith King, El Paso County Commissioner Sallie Clark, and City of Colorado Springs Chief of Staff Steve Cox were all present on the first day of demolition for the ceremonial "first swing of the sledgehammer" to mark the start of demolition.  

What the Project Involves



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 S. Nevada/Tejon interchange and the Cimarron interchange. Project boundaries on Cimarron are between 8th 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; 
  • Improved trail connectivity and aesthetic treatments.
