Travel Advisory

April 28, 2022 - Southeastern Colorado - Week of May 1 - Crews prepare for upcoming traffic switch on I-25

Colorado Springs — Colorado Department of Transportation and SEMA Construction continue work on the various improvements on I-25 between South Academy Boulevard and Santa Fe Avenue (Mile Post 135-127). Current work includes widening the Clover and Dry Wash Bridges, constructing substructure for the I-25 bridges over South Academy, and constructing the southbound I-25 lanes for the upcoming traffic switch.

Expect nighttime left lane closures on southbound I-25 between MP 124 and 135 to allow construction crews the necessary clearance to mill the shoulder and place embankment in the median. In addition, there will be a right lane closure on northbound I-25 (MP 131.7) to mill the pavement in the right lane.

There will be mobile operations on southbound I-25 from 9 a.m. to 3 p.m. Wednesday, May 4, to patch potholes on southbound I-25 between South Academy Boulevard and Santa Fe Avenue (MP 135-127).

Flagging operations will continue on Charter Oak Ranch Road with alternating lane closures Monday through Saturday, from 7 a.m. to 7 p.m., the closures are necessary so trucks can safely access to and from the job site and to allow crews to work on the drainage system. Please use extra caution when driving through the work zone.

Messaging boards and advanced warning signage have been installed along Colorado Highway 94. Roadwork is expected to being on May 2.

Traffic speeds will be reduced to allow construction equipment access to the work zone located in the median. DO NOT FOLLOW CONSTRUCTION VEHICLES.

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.
