Overnight closures and detours are planned for South Academy Boulevard in Colorado Springs during the week of November 2, 2025. The work is part of ongoing bridge expansion joint repairs and broader improvements under the Military Access, Mobility & Safety Improvement Program (MAMSIP).
The northbound lanes of South Academy Boulevard between the CanAm Highway (US 85/87) and Interstate 25 will be closed overnight on Sunday, November 2 from 7 p.m. to 4:30 a.m., with detours provided. On Monday night, November 3, a similar closure will occur between the CanAm Highway and Bradley Road.
Southbound closures are scheduled for Tuesday night, November 4 between Milton Proby Parkway and the CanAm Highway, and Wednesday night, November 5 between the CanAm Highway and I-25. Each closure runs from 7 p.m. to 4:30 a.m., with additional contingency nights possible on Thursday and Friday if needed.
Starting October 31, access to Fountain Creek Regional Trail north of South Academy Boulevard at Maxwell Street and Wilshire Drive will be closed for about one week to allow sidewalk replacement. Detour routes for cyclists and pedestrians are posted at the site.
On Sunday night, traffic on US 85/87 beneath the South Academy Boulevard bridge will shift into a head-to-head configuration in the northbound lanes while crews work on the bridge. Ongoing lane reductions continue on both directions of South Academy Boulevard between I-25 and Coventry Drive due to signal and island work; these changes are expected through November 9.
A temporary full closure of the southbound I-25 exit slip ramp at South Academy Boulevard is set for Wednesday, November 5 from 9 a.m. to 5 p.m., also affecting an adjacent auxiliary lane.
The project involves widening approximately one-and-a-half miles of South Academy Boulevard from two lanes to three in each direction near its southern end by I-25 through Milton Proby Parkway. Additional improvements include upgraded drainage systems, lighting enhancements, expanded shoulders, new sound walls, modified merge lanes, striping upgrades, and extensive bridgework. The project aims to address recurring congestion issues along this stretch of road.
According to CDOT’s safety assessment for this corridor, these improvements serve as mitigation measures designed to reduce crashes by addressing infrastructure deficiencies that contribute to accidents. Over twenty years following completion across all four MAMSIP corridors—including I-25—officials estimate there will be fewer deaths or injuries resulting from crashes.
The Military Access, Mobility & Safety Improvement Program is managed by El Paso County with partial funding from an $18 million BUILD grant awarded by the US Department of Transportation. The program supports more efficient travel along several major routes—including I-25—and strengthens connections among key military installations such as Fort Carson and Peterson Space Force Base in El Paso County. These efforts aim not only at improving safety but also at supporting regional economic stability through enhanced transportation links.
