Military Access, Mobility & Safety Improvement Project - Week of April 3

Travel Advisory

April 1, 2022 - Southeastern Colorado - Northbound and southbound temporary I-25 lane closures

Colorado Springs — Colorado Department of Transportation and SEMA Construction are continuing work on improvements to I-25 between South Academy Boulevard and Santa Fe Avenue (Mile Point 135-127). Current work includes widening the Clover and Dry Wash Bridges, constructing substructure for the I-25 bridges over South Academy, hauling dirt and building up the embankment for the I-25 roadway.

There will be alternating left and right lane closures, on north- and southbound I-25 (between MP 127-135) Monday, April 4 through Thursday, April 7, during evening hours, to allow crews to perform earthwork in the median and to repair damaged guardrail. In addition, there will be single lane closures Tuesday, April 5 from 9 am to 3 pm on northbound I-25 (between MP 128-135) for emergency pothole repairs.

There will be increased construction at the Dry Wash bridge as crews work on the piers and pier caps. With the variable nature of construction related to I-25 lane closures, please eliminate distractions and drive the posted speed limit to safely arrive at your destination.

Flagging operations will continue on Charter Oak Ranch Road with intermittent shoulder closures Monday through Saturday, from 7 a.m. to 7 p.m., allowing crews to safely continue work on the drainage system and dirt work. Please use extra caution when driving through the work zone.

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.

Traffic Impacts

I-25 between MP 127 and 135

  • Monday, April 4 through Thursday, April 7, 7 p.m. – 6 a.m. (nightly), alternating left and right lane closures on southbound I-25 to allow crews to perform earthwork in the median, repair damaged guardrail and install barrier.
  • Monday, April 4 through Thursday, April 7, 7 p.m. – 5 a.m. (nightly), alternating left and right lane closures on northbound I-25 to allow crews to perform earthwork in the median and repair guardrail.

Santa Fe Avenue and Charter Oak Ranch Road

  • Flagging operations with intermittent shoulder closures continue on Charter Oak Ranch Road and Santa Fe Avenue Monday, April 4 to Saturday, April 9, from 7 a.m. to 7 p.m. Closures are necessary to allow trucks access to and from the job site and to allow crews to work on the drainage system.

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.
