Project Overview

Interstate-25 – Safety and Efficiency Improvements

The improvements to I-25 addressed in this project are located along an approximately 7.5-mile segment of south I-25 beginning at South Academy Boulevard and extending to the Santa Fe Avenue (U.S. 85/87) exit at Fountain (MP 128), which exits to Gate 19 of Fort Carson. The project includes:

  • Replacement of two bridges crossing over South Academy Boulevard
  • Widening of both inside and outside shoulders and installing safety improvements
  • Concrete surface treatment overlay to provide an improved riding surface
  • Installation of median barrier
  • Rehab and widening work on four bridges
  • Installation of an I-25 southbound deceleration lane at the interchange with CO 16

Safety Benefits

CDOT conducted a safety assessment for the corridor to evaluate the magnitude and nature of safety problems and analyze the causes of crashes. These transportation improvements are mitigation measures to reduce crashes, improve infrastructure, and address physical deficiencies that contribute to crashes in the corridor. Over the next 20 years, the project is estimated to result in fewer deaths, injuries and crashes on the four MAMSIP corridors.

About the Military Access, Mobility & Safety Improvement Program Build Grant

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 Space Force Base, Cheyenne Mountain Space Force Station, and Schriever Space Force Base.

Know Before You Go

Travelers are urged to “know before you go.” Gather information about weather forecasts and anticipated travel impacts and current road conditions prior to hitting the road. CDOT resources include:
