The northbound South Academy Boulevard off-ramp to Bradley Road will be temporarily closed on Friday, March 8, 7 p.m. to Saturday, March 8, 3 p.m. to allow crews to install drainage pipe across the roadway.

A detour will be in place: traffic intending to exit northbound South Academy Boulevard to Bradley Road will continue north to Milton E. Proby Parkway, turn right and travel to Hancock Expressway, turn right and continue to Bradley Road.

Effective Feb. 21, two westbound lanes on South Academy Boulevard are open, along with a single eastbound lane using the westbound South Academy bridge over Fountain Creek. Speeds across the detour cross over lanes and across the bridge reduced to 35 MPH. Bridge lanes are 11 feet wide with a 2-foot shoulder. Oversize loads are not allowed on the bridge during this closure.

Motorists are advised to use caution at all entrance ramps as merge lengths have been shortened. In particular, motorists should be prepared to stop on the US 85/87 on-ramp to eastbound South Academy since merge area is greatly reduced. Work crews installed signage and flashing beacons to alert traffic to the lane lengths.

All lanes on Bradley Road under South Academy Boulevard have been shifted to the center of the roadway to allow crews to perform work on new bridge piers.

A left lane closure is ongoing for northbound and southbound South Academy Boulevard over Bradley Road to allow crews to perform bridge 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 (U.S. 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 CO 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 U.S. Highway 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 20 years, the project is estimated to result in fewer deaths, injuries and crashes on the four MAMSIP corridors.

About the Military Access, Mobility & Safety Improvement Program Build Grant

Colorado Department of Transportation (CDOT) has initiated a program to deliver more efficient and safer mobility along I-25, Colorado Highway 94, South Academy Boulevard, and Charter Oak Ranch Road, enabling economic stability and development. The Military Access, Mobility & Safety Improvement Program is partially funded through an $18 million BUILD grant award from the US Department of Transportation. The delivery of these improvements will strengthen and enhance the redundancy of strategic movement between the nationally significant El Paso County military installations of Fort Carson, Peterson Space Force Base, Cheyenne Mountain Space Force Station, and Schriever Space Force Base.

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:
