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.
