SEMA Construction has partnered with CDOT on this important CM/GC project, currently in preconstruction. This $127M extensive safety and mobility-improvement project will focus on strategically enhancing connectivity and accessibility at several military bases and facilities in and around Colorado Springs.
Project Components Include:
The team will build an approximate mile-long passing lane on westbound CO 94 at mile point (MP) 5.5 to improve visibility and allow vehicles to safely pass along this stretch of highway.
The team will widen a section of South Academy Boulevard to three lanes to alleviate recurring congestion. Work will include striping, expanding the road into shoulders, modifying merge lanes and minor bridgework.
The team will install median barriers on a 7.5-mile stretch of I-25 between the exits at South Academy Boulevard and Santa Fe Avenue. Other work includes widening the inside and outside shoulders to 12 feet, replacing two bridges across South Academy, work on six other bridges and installing infrastructure to support transportation technologies.
The team will improve Charter Oak Ranch Road and Santa Fe Avenue intersection, reconstructing the roadway out to Gate 19 of Fort Carson.
