Travel Advisory

Aug. 13, 2026 - Southeastern Colorado - Full closure scheduled from midnight to 5 a.m.

Colorado Springs — The Colorado Department of Transportation and its contract partner, SEMA Construction, Inc., will implement an overnight full closure of southbound Interstate 25 at Garden of the Gods Road (near Exit 146) on Wednesday, Aug. 19. This closure is necessary to ensure the safety of the traveling public and help minimize impacts to daytime traffic.

Southbound I-25 will be closed overnight to allow crews to safely install a new interstate directional sign structure near Exit 146, south of Garden of the Gods Road. The southbound on-ramp at Garden of the Gods Road will be closed, while the off-ramp will remain open. The new overhead structure will provide advance information, helping motorists identify upcoming exits and safely navigate the corridor.

Motorists are encouraged to visit COtrip.org before traveling to check the latest road conditions and lane closure information. Closure schedules are subject to change due to weather, field conditions and construction progress.
