I-25 / CO 94 Safety Improvement Project Continues Progress with Evaluation of Bridge Surfaces

August 28, 2020 - Southeastern Colorado - Traffic Advisory, Week of August 30

COLORADO SPRINGS — Motorists will see testing work along Interstate-25 as the Colorado Department of Transportation continues advancement of the project design for the I-25 Safety & Efficiency Improvements Component, one of the major parts of the Military Access, Mobility & Safety Improvement Project (MAMSIP). CDOT will assess the condition of the bridge surfaces by drilling cores on I-25 at Clover Ditch, Mile Point 131.23, and Dry Gulch, Mile Point 128.35. This testing will require single lane closures on I-25.

Overnight Closures Required – Sunday and Monday

Northbound and Southbound I-25 Single Lane Closures

8 p.m. – 5 a.m., Sunday and Monday

  • Single southbound or northbound lane

  • I-25 between Mesa Ridge Parkway and Santa Fe Avenue (milepost 128 – 132)

  • Speed reductions to 65 mph will be in place. Motorists should expect delays. 

  • Dates of work are weather permitting.

CDOT continues to show progress on the BUILD Grant as the project moves forward to construction this fall. 

MAMSIP is managed and delivered by CDOT through the Better Utilizing Investments to Leverage Development, or BUILD Grant program, and includes project components on corridors owned by El Paso County (South Academy Boulevard and Charter Oak Ranch Road). This program provides an opportunity for the Department of Transportation (DOT) to invest in road, rail, transit and port projects that promise to achieve national objectives. Partners contributing to the funding of these improvements include:

  • Pikes Peak Rural Transportation Authority (PPRTA)

  • Pikes Peak Area Council of Governments (PPACG)

  • Central Front Range (CFR) Transportation Planning Region

  • Colorado Chapter of the Federal Highway Administration (FHWA)

Project stakeholders include multiple jurisdictions, the region’s military installations and the community. Funding is guaranteed through the duration of the project. 



  • Replacement of two bridges crossing over South Academy Boulevard

  • Widening of both inside and outside shoulders and installing outside guardrails

  • Concrete surface treatment overlay to provide an improved riding surface for this 7.5‐mile segment

  • Installation of median barriers the entire length of this corridor

  • Work on four bridges along the corridor and

  • Installation of I-25 southbound deceleration lane at the interchange with CO 16

Collectively, this work to the I-25 corridor will significantly improve safety through reduction in accidents, injuries and fatalities. Replacement of bridges which have exceeded their useful life, as well as work to minor bridges along the corridor, will reduce scheduled and unscheduled maintenance and repairs on these infrastructure assets. In addition, introduction of I-25 southbound deceleration lane at the CO 16 interchange will contribute to greater efficiency of vehicular movement. Undertaking these improvements to I-25 will effectively improve mobility and safety outcomes along one of the state’s busiest interstate corridors while concurrently ensuring economic vitality provided by this crucial north to south route is maintained.

Colorado Department of Transportation (CDOT) has initiated a program to deliver more efficient and safer mobility along I-25, Colorado Highway 94, South Academy Boulevard, and Charter Oak Ranch Road, enabling economic stability and development. The Military Access, Mobility & Safety Improvement program is partially funded through an $18 million BUILD grant award from the US Department of Transportation. The delivery of these improvements will strengthen and enhance the redundancy of strategic movement between the nationally significant El Paso County military installations of Fort Carson, Peterson Air Force Base, Cheyenne Mountain Station, and Schriever Air Force Base. 


The following tips are to help you stay safe while traveling through maintenance and 

construction work zones.

  • Do not speed in work zones. Obey the posted speed limits.

  • Stay Alert! Expect the unexpected.

  • Watch for workers. Drive with caution.

  • Don't change lanes unnecessarily.

  • Avoid using mobile devices such as phones while driving in work zones.

  • Turn on headlights so that workers and other drivers can see you.

  • Be especially alert at night while driving in work zones.

  • Expect delays, especially during peak travel times.

  • Allow ample space between you and the car in front of you.

  • Anticipate lane shifts and merge when directed to do so.

  • Be patient!


The CDOT Whole System — Whole Safety initiative is designed to heighten safety awareness by taking a systematic statewide approach to safety combining the benefits of CDOT’s operations, programs addressing driving behaviors, and  our built environment. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.


CDOT has approximately 3,000 employees located throughout Colorado and manages more than 23,000 lane miles of highway and 3,429 bridges. CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated interregional express service. Governor Polis has charged CDOT to further build on the state’s intermodal mobility options.
