Military Access, Mobility & Safety Improvement Project

Travel Advisory

June 3-11 - Interstate 25 southbound traffic will be shifted to temporary configuration on June 1

Fiber installation location mapColorado Springs —Colorado Department of Transportation and SEMA Construction continue work on improvements on I-25 between South Academy Boulevard and Santa Fe Avenue (Mile Post 135-127). As part of the I-25 improvement project, traffic will temporarily shift southbound I-25 easterly to the newly constructed inside lanes between South Academy Boulevard and Colorado Highway 16 (Mesa Ridge Parkway) beginning 7 a.m. Saturday, June 4. Traffic on I-25 will be head-to-head, separated by temporary barrier with 11 ft. lanes and 2 ft. shoulders. Crews will also be installing signage throughout the project along I-25. Speed limits have been reduced to 55 MPH between MP 127 and MP 135.5. There will be a left lane closure on southbound I-25 between Mile Post 135 to 132, on Friday night, June 3, so crews can place embankment in the median. Traffic shift and embankment construction schedule is weather-dependent and subject to change.

Final work on the switch will take place approximately one month later with a shift of southbound I-25 to the newly constructed lanes between CO 16 and Santa Fe Avenue. Motorists should be aware as they will also encounter a new southbound on-ramp configuration from South Academy Boulevard and a new southbound to westbound off-ramp configuration to CO 16 with the I-25 traffic switch. This traffic switch will be in place through early 2023 to allow for the construction of the new southbound lanes with concrete that will provide increased stability and durability.

The new traffic configuration will be in place 24 hours a day, 7 days a week. The speed limit in this area has been reduced to 55 MPH. Motorists are urged to use extra caution while traveling in the new traffic pattern. Fines will be doubled through the construction zone.

As an added safety measure, CDOT has built four temporary emergency pull-off areas on the northbound side and two emergency pull-off areas on the southbound side that drivers can use if necessary.

Flagging operations will continue on Charter Oak Ranch Road with alternating lane closures and alternating one-way traffic operations 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 perform paving operations.

Nighttime work will take place nightly Sunday through Tuesday, with a right lane closure eastbound and turn lane closure westbound on Colorado Highway 94 at MP 6 to 8, to allow crews to perform striping activities and set barriers prior to the traffic switch. A full closure is in place at the intersection of CO 94 and North Blaney Road with traffic detoured to North Curtis Road. The detour will remain in place until mid-summer. Motorists traveling on CO 94 are cautioned to watch for motorists turning onto CO 94 from south Blaney Road. Landfill Vehicles utilizing Waste Management’s facility will use Curtis Road to Access landfill via the Davis Road detour then southerly on North Blaney Road. North Blaney Road access to CO 94 will be closed.

A Courtesy Patrol will be driving the work zone and will respond to incidents when notified. Hours of operation are 8 a.m. to 7 p.m., Monday through Friday and holidays.

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

Construction schedules are weather-dependent and subject to change.

Traffic Impacts

I-25 between MP 127 and 135

  • Friday night, June 3, 9 p.m. to 5 a.m., left lane closure on southbound I-25 MP 135 to 132, to allow crews to place embankment in the median.
  • Monday, June 6 to June 9, 7 p.m. to 6 a.m., alternating right and left lane closure on the southbound I-25 MP 131 to 135, to allow crews to install signage.
  • Monday, June 6 to June 9, 7 p.m. to 5 a.m., alternating right and left lane closure on the northbound I-25 MP 131 to 135, to allow crews to install signage.
  • Santa Fe Avenue and Charter Oak Ranch Road
  • Flagging operations with alternating lane closures and alternating one-way traffic continues on Charter Oak Ranch Road and Santa Fe Avenue Monday, June 6 to Saturday, June 11, from 7 a.m. to 7 p.m., to allow crews to preform paving operations.

Colorado Highway 94

  • Sunday, June 5, 7 p.m. to 5 a.m., right lane closure eastbound and turn lane closure westbound on Colorado Highway 94 at MP 6 to 8, to allow crews to perform striping activities and set barriers prior to the traffic switch.
  • Monday, June 6 to Tuesday, June 7, 8 p.m. to 5 a.m., right lane closure eastbound and turn lane closure westbound on Colorado Highway 94 at MP 6 to 8, to allow crews to perform striping activities and set barriers prior to the traffic switch.
  • A full closure will be in place of north Blaney Road. This closure will remain in place through early fall.

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.
