The Colorado Department of Transportation and contractor SEMA Construction will temporarily close the southbound on-ramp at I-25 and CO 16 (Mile Point 132/131- Mesa Ridge Parkway) along with a southbound right lane on I-25. The nighttime closures are scheduled nightly Monday, Oct. 17 and Tuesday, Oct. 18 to allow the implementation of the on-ramp traffic switch from CO 16 to the new configuration.
There will be nighttime full closures of east- and westbound South Academy Boulevard, starting Monday, Oct. 17 to Friday, Oct. 21, so construction crews can install overhangs and form the deck edge for the new I-25 bridge.
Detours will be in place:
Eastbound South Academy Boulevard traffic will be diverted south on I-25 to Colorado Highway 16 (exit 132A), where they will turn around and re-enter I-25 north to South Academy Blvd
Westbound South Academy Boulevard traffic will be diverted north on I-25 to Lake Ave./South Circle Dr. (exit 138), where they will turn around and re-enter I-25 south to South Academy Blvd.
Use signed detour route. Fort Carson personnel should consider using alternate gates.
Head-to-head traffic continues on I-25, separated by temporary barrier with 11 ft. lanes and 2 ft. shoulders. This traffic configuration will be in place 24 hours a day, 7 days a week. Normal working hours will be 7 a.m. to 9 p.m., Monday through Friday. The speed limit in this area has been reduced to 55 MPH. Slight traffic delays are expected and motorists are urged to use extra caution while traveling in the new traffic pattern. Fines will be double through the construction zone.
Charter Oak Ranch Road and Santa Fe Avenue roundabout is now open, however Champlin Lane is not accessible from Santa Fe, a detour is in place while crews construct the roadway. To access Champlin Lane traffic will continue to the roundabout, then turn right onto Charter Oak Ranch Road then turn right onto Champlin Drive, then right to Champlin Lane.
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 south I-25 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. The project includes:
-
- 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
- Installation of median barrier
- Rehab and widening work on four bridges
- Installation of an I-25 southbound deceleration lane at the interchange with Colorado Highway 16
- 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 20 years, the project is estimated to result in fewer deaths, injuries, and crashes on the four MAMSIP corridors.
