I-25 Acceleration/Deceleration Lanes from Fillmore Street to Garden of the Gods Road

About the Project:

While working on the auxiliary lane project, the aging bridge on I-25 over Ellston Street will be reconstructed and widened. 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 Nov. 2025.

The growth of the community and business expansion has necessitated the initiation of the improvement project. We will be adding continuous acceleration and deceleration lanes to both the northbound and southbound directions of I-25, spanning from Garden of the Gods Road to Fillmore Street. The new lanes will be constructed/added where the existing right shoulder is located. 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. Curve cross slope adjustments will be implemented to address drainage concerns on the road.

While working on the auxiliary lane project, the aging bridge on Ellston Street over I-25 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 automated vehicle and queue detection to mitigate any traffic backups by adjusting meter timing.

Project Benefits

  • Auxiliary lanes help to balance traffic and facilitate the positioning of drivers at exits and the merging of drivers at entrances.
  • Resurfacing the roadway will create a smoother surface.
  • To help with drainage issues on the roadway, curve cross slope corrections will be made.

Work Schedule:

  • Daytime work hours range from 7 a.m. to 7 p.m., Monday through Friday.
  • Overnight work hours from 10 p.m. to 5 a.m., Monday through Thursday.

Traffic Impacts:

Motorists can expect the following impacts during the period of construction:

  • Single and double lane closures on I-25
  • Potential lane closures on the on-ramps and off-ramps is expected.
