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 (CO 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 Colorado Highway 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.
