El Paso County – MAMSIP – South Academy Boulevard Widening Project

There are ongoing lane reductions on southbound South Academy Boulevard between I-25 and Coventry Drive to allow crews to continue traffic signal and island installations. This alignment is anticipated to remain in place through October 12.

  • The two left turn lanes for the southbound I-25 on-ramp (MP 135) will be reduced to one left turn lane.
  • There will still be two thru lanes on southbound South Academy Boulevard in this area.

Delays should be expected, particularly during peak travel times. Drivers should allow extra time, maintain safe following distances, and merge early and safely when approaching the work zone. Drivers planning to access I-25 southbound will need to move to the center lane well in advance.

Beginning Monday, Sept. 29, the pedestrian bridge over South Academy Boulevard near Wilshire and Welton will be closed for approximately one week (Monday, Oct. 6) to remove and replace sidewalk on the north side of the pedestrian bridge. Detours will be in place:

  • Cyclists and pedestrians can use Wilshire Drive and Welton Drive to cross over on Hartford Street or use the Fountain Creek Regional Trail.

A shift of east- and westbound South Academy Boulevard between I-25 and Fountain Creek towards the center is ongoing to allow crews to work on the outside lanes. This alignment is anticipated to remain in place until November 2025.

Motorists should use caution as lanes will be narrowed across the southbound bridge over US 85/87 so crews can continue bridge work.

These closures are weather-dependent and subject to change.

Project Overview

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 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:
