CDOT I-25 South Gap Wildlife Fence Project


Project Summary: In response to incidents of vehicle/animal collisions along the I-25 corridor in Douglas County, the Colorado Department of Transportation (CDOT), Colorado Parks and Wildlife (CPW), the City of Castle Pines, the Town of Castle Rock and Douglas County have partnered to install 14 miles of wildlife fencing on the east and west side of I-25, from the Ridgegate exit (MM 192) in Lone Tree to the Meadows/Founders exit in Castle Rock (MM 184). In total, CDOT is currently installing four new wildlife crossings and more than 30 miles of deer fence as part of the I-25 South Gap project, which stretches across two counties (Elbert and Douglas Counties). CDOT began fence construction in April 2022 with the installation to be completed in January 2023.

Maps of Wildlife Fence Locations:
Please note, on the maps that Alternate B was chosen as the alignment along I-25 instead of along Havana. Alternate B allows us to avoid a costly and potentially unsafe deer guard on Havana.

Timeline of Project: 

  • April 2022 – Construction began
    CDOT began fence construction with the installation to be completed in summer 2022.
  • August 2022 – After several months of work, the project team is wrapping up fence installation on the west side of I-25 (southbound) between Castle Rock Parkway and Ridgegate Parkway.
  • November – December 2022 – The fencing is approximately 75% completed along I-25.
  • 2023 – The fencing portion of the install is finalized and crews are wrapping up game ramps and other miscellaneous items – project is anticipated to be completed in 2023.


April 24 – May 1, 2023:

Traffic Impacts: During the week of April 24, crews will be seeding game ramps along I-25 from Ridgegate Parkway to Founders Parkway, occupying the interstate shoulder.

  • Nighttime work is expected to resume in early May to finalize the concrete rehabilitation portion of the project.
