Travel Advisory

July 18, 2022 - Southeastern Colorado - I-25 lane closures for continued work on traffic switch

Colorado Springs — As part of the work being performed by the Colorado Department of Transportation and SEMA Construction, motorists should be aware as they will encounter a traffic switch on southbound I-25 between South Academy Boulevard and Colorado Highway 16 (Mesa Ridge Parkway), a new southbound on-ramp configuration from South Academy Boulevard and a new southbound to westbound off-ramp configuration to CO 16. There will be additional nighttime lane restrictions to continue work on the southbound I-25 lane shift from CO 16 to Santa Fe Avenue. The traveling public will encounter this southbound I-25 shift in late July. This traffic configuration will be in place through early 2023 to allow for the construction of the new southbound lanes with concrete pavement that will provide increased stability and durability.

On Thursday, July 21 and Friday, July 22, there will be nighttime single lane restrictions work on southbound I-25 between CO 16 and Santa Fe Avenue (MP 128.3) to place temporary concrete barrier.

Flagging operations will continue on Charter Oak Ranch Road with alternating lane closures and alternating one-way traffic operations Monday through Friday, from 7 a.m. to 7 p.m. Santa Fe Boulevard and Charter Oak Ranch Road intersection will remain closed and a detour in place so construction crews can continue paving, curb and gutter, and drainage installation. Use extreme caution in the area.

A full closure remains in place at the intersection of Colorado Highway 94 and North Blaney Road with traffic detoured to North Curtis Road as construction crews continue work on the Jug Handle intersection. The detour will remain in place until late-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 is closed.

On-going traffic shift with a right lane closure eastbound and turn lane closure westbound on CO 94 with head-to-head traffic, between MP 6 to MP 8 to allow crews the necessary room to perform earthwork activities for the widening of CO 94 and the new Jug Handle intersection. A traffic shift is in place. Use extreme caution, speed limit 50 MPH.

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.

Construction schedules are weather-dependent and subject to change.

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
  • Installation of I-25 Southbound deceleration lane at the interchange with Colorado Highway 16


Charter Oak Ranch Road is accessible off Interstate 25 via Santa Fe Avenue (Colorado Highway 85) and is the only access to Gate 19 of Fort Carson, the region’s largest employer. Project improvements include:

  • Improve infrastructure
  • Enhance connectivity and efficiency for Charter Oak Ranch Road, the entry point to Fort Carson’s Gate 19 from the I-25 corridor

Colorado Highway 94
Safety and efficiency improvements with the addition of passing lanes, turn lanes, road widening and the installation of fiber on CO 94, which connects Schriever Space Force Base with Peterson Space Fore Base and central Colorado Springs.

Safety Benefits

CDOT conducted a safety assessment for the corridor to evaluate the magnitude and nature of safety problems and analyze the causes of crashes. These transportation improvements are mitigation measures to reduce crashes, improve infrastructure, and address physical deficiencies that contribute to crashes in the corridor. Over the next twenty years, the project is estimated to result in fewer deaths, injuries, and crashes on the four MAMSIP corridors.

Know Before You Go

Travelers are urged to “know before you go.” Gather information about weather forecasts and anticipated travel impacts and current road conditions prior to hitting the road. CDOT resources include:
