Overnight Northbound and Southbound I-25 Single Lane Closures

Monday night, Mar. 9 to Thursday night, Mar. 12

  • Closure hours each night will be 8:30 p.m. to 5 a.m.

  • Southbound/northbound lanes and outside shoulder closures on I-25

  • Southbound I-25 between South Academy Boulevard and Santa Fe Avenue (Milepost 135 to 127)

I-25 Safety Improvement project is part of Military Access, Mobility & Safety Improvement Program Grant and includes:

  • 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 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.
