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 the corridor 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.
  • 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 for this 7.5-mile segment;\Installation of median barrier the entire length of this corridor
  • Rehab and widening work on four bridges along the corridor, and
  • Installation of I-25 Southbound deceleration lane at the interchange with Colorado Highway 16.

Safety Benefits

The safety enhancements relate to the potential to reduce crashes, improve infrastructure, and address physical deficiencies that contribute to crashes in the corridor. CDOT conducted a safety assessment for the corridor to evaluate the magnitude and nature of safety problems and analyze the causes of crashes.

The proposed transportation improvements are mitigation measures to reduce crashes and improve safety in the corridor. It is estimated that the delivery of the MAMSIP project will, over its’ twenty years of operation, result in fewer deaths, injuries, and crashes on the four corridors the project addresses.
