I-25 South GAP
The project’s final construction season will focus on permanent paving and striping, installation of tolling infrastructure, completion of the extensive wildlife mitigation system, permanent sign installation and landscaping. Motorists can expect a variety of impacts along the 18-mile corridor during this work, including daytime and overnight lane closures.

General Lane Closure Hours

Extended Express Lane Closures
This spring and summer, crews will require extended Express Lane closures for as long as two weeks for drainage work in the median area of I-25. The two general purpose lanes will remain open during peak travel hours, but motorists can expect a double lane closure during overnight construction hours. Drivers should stay on I-25 and avoid taking detours. Stay tuned to our various communication channels for more information on this work.

I-25 Wildlife Fencing  – northbound and southbound I-25 from E Wolfensberger Road in Castle Rock (Mile post 181.75) to Lincoln Avenue near Lone Tree (MP 192.75)
CDOT Crews will be working daytime and nighttime hours throughout the project, April to Dec. 2022. Daytime working hours will be focused on building wildlife fencing, guardrails, and two deer guard installations at Happy Canyon Road. Nighttime working hours will primarily be dedicated to roadwork patching and will begin in late April.

The concrete rehabilitation will improve and prolong the life of the road surface, creating a smoother and safer travel path for motorists. Building wildlife fencing, and deer guards will significantly reduce the number of accidents related to animals crossing the interstate.
