El Paso County – MAMSIP – South Academy Boulevard Widening Project
Effective December 7, a new detour is in place for westbound travel on South Academy Boulevard between US 85 and I-25 over Fountain Creek.
Two eastbound lanes on South Academy Boulevard are open, along with a single westbound lane using the eastbound South Academy bridge over Fountain Creek. Speeds across the detour cross over lanes and across the bridge will be reduced to 35 MPH.
Bridge lanes will be 11 feet wide with a 2-foot shoulder. Oversize loads will not be allowed on the bridge during this closure. The closure of the westbound South Academy Boulevard bridge is ongoing for scour bridge investigation and countermeasures.
A left lane closure is ongoing for northbound and southbound South Academy Boulevard over Bradley Road to allow crews to perform bridge work. This left lane closure will be in place for approximately three months.
There will also be an ongoing auxiliary lane closure on northbound South Academy Boulevard between Hartford Street and Fountain Creek through mid-December for drainage line work.
These closures 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 (US 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
South Academy Boulevard Widening Project
The improvements to South Academy Boulevard in this project are located on South Academy Boulevard at the southern mile and a half of this arterial road from the I-25 interchange, crossing US 85/87, and continuing to the road’s approach to Milton Proby Parkway (which connects to Powers Boulevard/CO 21). Construction focuses on widening an approximately 1.5-mile section of South Academy Boulevard from two lanes to three in each direction to alleviate recurring congestion. The project includes improved drainage facilities, lighting, striping, and expanded shoulders, modified merge lanes, sound walls and bridgework. The project is expected to be complete by early 2026. This project is managed by El Paso County.
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.
