Military Access, Mobility & Safety Improvement Project
South Academy Boulevard widening and Pikes Peak region corridors, El Paso County, CO
The Military Access, Mobility & Safety Improvement Project (MAMSIP) is a $161 million, five-year program to improve the corridors connecting Fort Carson, Peterson Space Force Base, Schriever Space Force Base, and Cheyenne Mountain Space Force Station — funded by CDOT, El Paso County, the Pikes Peak Rural Transportation Authority, and an $18.35 million federal BUILD grant. Built by SEMA Construction from June 2021 to July 2026, the program delivered safety improvements and a jug-handle intersection on CO 94; a full rebuild of Charter Oak Ranch Road with a new roundabout at Santa Fe Avenue; 7.5 miles of I-25 work between South Academy Boulevard and Fountain, including two replacement bridges, a concrete overlay, and a full-length median barrier; and finally the widening of South Academy Boulevard from two to three lanes in each direction, with bridge widening over Fountain Creek, US 85/87, and Bradley Road.<br /> <br /> Vivid Engineering served as the lead materials quality assurance testing firm for the program, overseeing all materials documentation, field testing, and inspection — including the South Academy Boulevard widening in El Paso County — to verify that every element met CDOT and FHWA standards for safety and durability.
