March 4, 2022 - Southeastern Colorado - Nighttime north- and southbound lane closures on I-25

Colorado Springs — Colorado Department of Transportation and SEMA Construction are continuing to work on I-25 between South Academy and Santa Fe Avenue (Mile Point 135-127). Work currently is for the widening of the Clover and Dry Wash Bridges, constructing the substructure for the I-25 bridges over South Academy and hauling in and building up the embankment for the I-25 roadway. During the evening hours, from Sunday, March 6 through Thursday, March 10, the project work will require lane closures on north and southbound I-25.

There will be nightly alternating left and right lane closures northbound on I-25, Sunday, March 6 through Tuesday, March 8, so crews can install advance warning signs and mile post signs on the I-25. Commuters will encounter these closures between MP 127 and 135. There will also be alternating left and right lane closures on southbound I-25, Wednesday and Thursday nights, for continued installation of signage in the same area. With the variable nature of the lane closures on I-25, please eliminate your distractions and drive the posted speed limit so you and your passengers arrive safely to your destination.

Flagging operations on Charter Oak Ranch Road will continue with intermittent shoulder closures Monday through Friday, from 7 a.m. to 5 p.m. Crews will be installing storm drainage across the road on Saturday, March 12 from 7 a.m. to 5 p.m. with alternating lane closures reducing traffic to one lane. These closures will allow crews to safely continue their work on drainage and dirt work. Please use extra caution when driving through the work zone.

Construction schedules are weather-dependent and subject to change.

Motorists are encouraged to register for text alerts by Texting MAMSIP to 888-970-9665

A Courtesy Patrol will be driving the work zone and will respond to incidents when notified. Hours of operation are 7 a.m. to 6 p.m., Monday through Friday and holidays.

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.
