Prioritized Project Goals


Project goals were established and approved by the Executive Oversight Committee in November 2013. The goals will provide direction to the project team and to the proposing Design-Build contractor teams to assist them in submitting a "best value" proposal.


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 July 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 will also be used to help establish the project requirements." 

-- Dave Watt, CDOT Region 2 Resident Engineer

Project Schedule


A contract award to a Design-Build team is anticipated by the end of 2014. Construction is expected to begin in mid-2015 with traffic in its final configuration by July 2017. Design-Build contractors have the opportunity to submit enhanced schedules as part of their proposals.

CDOT Moves Ahead with Critical 

Interchange Design-Build Project


As far as interstate interchanges go, this one has more than served its life span. Having been built in 1959 consistent with current design standards of that time, the Interstate 25/Cimarron Interchange structure is badly in need of greater efficiency and correcting existing safety and design deficiencies. The planned upgrades include reconstruction of the I-25 interchange between Colorado Avenue on the north and the Tejon interchange to the south. The U.S. 24 project boundaries are between 8th Street on the west and the Union Pacific-BNSF railroads joint line/Cimarron Street Bridge to the east. The reconstructed interchange will respond to the travel demands in the area with improved traffic operations and safety.


Construction cost for the project is estimated between $65 and $85 million of the $95 million total project cost, which includes local funding from the City of Colorado Springs ($5 million) and El Paso County ($1 million). A Design-Build delivery process will be used for the reconstruction of the interchange.


This project does not include reconstruction of the 8th Street intersection at U.S. 24. That will be a separate project and funding for it has not been identified.


"The Colorado Department of Transportation recognizes how important the I-25/Cimarron interchange is to the Pikes Peak community. It's been on the state's list of needed projects for several years," said Dave Watt, CDOT Region 2 Resident Engineer. "With its reconstruction, the interchange will be moved 20 to 25 feet to the west, softening the curve and the current highway alignment. When complete, the interchange will function better, safely handle more vehicles and enhance travel for those using both I-25 and U.S. 24/Cimarron Street.


"The project's aesthetics will consider the interchange as a gateway to downtown Colorado Springs and the U.S. 24 corridor to the mountains. The project will also preserve existing and support future multi-modal operational uses for vehicles, trucks and transit as well as trail and creek connections for bikes and pedestrians. And, it will create and enhance opportunities for trail and creek amenities along U.S. 24 and Fountain Creek," Watt said.


Specifically, the project will:

  • Reconstruct I-25 to provide improved highway alignment and improved ramps and acceleration and deceleration lanes and shoulders, for better operations and safety on I-25;
  • Reconstruct I-25 bridge structures;
  • Enhance interchange traffic flow and safety operations; and
  • Provide better trail connections, improve water quality, and aesthetic enhancements.

Planned improvements are described in the I-25 Environmental Assessment (EA) completed for the project in summer of 2004 and the U.S. 24 West EA currently under review. 

Project to be Constructed Using 

Design-Build Delivery Method


"CDOT has determined that Design-Build delivery provides the best process to complete the I-25/Cimarron Interchange design and construction," Watt said. "It is a method whereby the design and construction phases are combined into one contract." 


The design-build process:

  • Optimizes project goals;
  • Expedites project delivery by integrating the design and construction schedules;
  • Encourages design and construction innovation; and
  • Promotes an efficient project with maximum benefit for available funds.

CDOT Requests Letters of Interest 

for Design-Build Services


The procurement process for the project started last month with the distribution of Request for Letters of Interest from companies or teams interested in providing D/B services for the reconstruction of the I-25/U.S. 24-Cimarron Street Interchange project. Letters were sent to the design and contractor community and posted to the CDOT website.


After Statements of Qualifications from prospective D/B teams are evaluated, CDOT will establish a short list of eligible teams. A Request for Proposals (RFP) will be sent to those teams, and submittals will be evaluated using "best-value" criteria. The RFP will include a conceptual design and will encourage innovation from the private sector to maximize project goals. 

Stakeholder Involvement


Interacting and communicating with stakeholders and the public for the project began in October 2013 and will continue throughout the procurement and the design/construction process.


Many community organizations and interests are represented on the:

  • Working Team Stakeholders committee 
  • Project Management Team 
  • Executive Oversight Committee  
  • Various Technical Teams 

The committees have been formed and involved early in the process. They will meet regularly throughout the project's procurement and design phase providing input in advance of construction.
