Military Access, Mobility & Safety Improvement Project Closures Week of March 27

Travel Advisory

March 25, 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.

Commuters will experience alternating left and right lane closures north and southbound I-25 between MP 127 and MP 135, during the evening hours from Sunday, March 27 through Tuesday, March 29 as construction crews perform striping activities and the installation of rumble strips. Rumble strip installation will require a mobile closure operation. Expect 10-minute delays.

The traveling public will continue to see earthwork taking place in the median. There will be a left lane closure nightly on Wednesday, March 30 and Thursday, March 31, southbound on I-25 between MP 127-135, so construction crews can perform earthwork in the median.

Work continues on the bridges over South Academy, as crews form and install rebar for the columns in the median of South Academy and place permanent soil wall for the south abutment wall.

There will be increased construction at the Dry Wash and Clover Ditch bridges as crews work on forming and pouring concrete for the new footers, piers and pier caps. With the variable nature of construction related 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.

  • Sunday, March 27, 8:00 p.m. to 5:00 a.m., alternating left and right lane closure on northbound I-25 between MP 135-127, so construction crews can remove striping and install rumble strips.
  • Sunday, March 27, 9:00 p.m. to 6:00 a.m., alternating left and right lane closure on southbound I-25 between MP 127-135, so construction crews can remove striping and install rumble strips.
  • Monday, March 28 and Tuesday, March 29, 7:00 p.m. to 5:00 a.m., alternating left and right lane closure on northbound I-25 between MP 135-127, so construction crews can remove/install striping and install rumble strips.
  • Monday, March 28 and Tuesday, March 29, 7:00 p.m. to 6:00 a.m., alternating left and right lane closure on southbound on I-25 between MP 127-135, so construction crews can remove/install striping and install rumble strips.
  • Wednesday, March 30 and Thursday, March 31, 7:00 p.m. to 6:00 a.m., left lane closure southbound on I-25 between MP 127-135, so construction crews can perform earthwork in the median.

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, March 28 to Saturday, April 2, 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.

Remember: Slow For The Cone Zone

The following tips are to help you stay safe while traveling through maintenance and construction work zones.

  • Do not speed in work zones. Obey the posted speed limits.
  • Stay Alert! Expect the unexpected.
  • Watch for workers. Drive with caution.
  • Don't change lanes unnecessarily.
  • Avoid using mobile devices such as phones while driving in work zones.
  • Turn on headlights so that workers and other drivers can see you.
  • Be especially alert at night while driving in work zones.
  • Expect delays, especially during peak travel times.
  • Allow ample space between you and the car in front of you.
  • Anticipate lane shifts and merge when directed to do so.
  • Be patient!
