About the Project
The Colorado Department of Transportation and its contracting partner, SEMA Construction, began improvements along Interstate 25 from Garden of the Gods Road to Fillmore Street in Colorado Springs at the end of October. The project will enhance safety for Colorado’s traveling public by adding acceleration and deceleration lanes. The anticipated completion date of the project is late August 2026.
The growth of the community and business expansion has necessitated the initiation of the improvement project. Continuous acceleration and deceleration lanes will be added to both the northbound and southbound directions of I-25, spanning from Garden of the Gods Road to Fillmore Street. These auxiliary lanes aim to even out traffic flow and assist drivers in merging and exiting traffic efficiently. Additionally, to enhance road safety, the roadway will undergo resurfacing and adjustments will be implemented to address drainage concerns on the road, as well as the installation of permanent stop signs at Chestnut Street after the project is completed.
While working on the auxiliary lane project, the aging bridge on I-25 over Ellston Street will be reconstructed and widened. Additionally, bridge deck repairs will be made on the Garden of the Gods overpass structure. Upgrades to the intelligent transportation system (ITS) infrastructure (fiber optics and ramp meter station) will help with the flow of traffic to monitor, trigger and time vehicle release with automatic vehicle and queue detection to mitigate any traffic backups by adjusting meter timing.
