Flagstaff's ongoing effort to harmonize nature with transportation took a solid leap forward as construction crews recently hoisted 13 massive girders into place for a new wildlife overpass that will straddle the roaring traffic of Interstate 17. This structure is part of a collaborative $15.8 million project between the Arizona Department of Transportation (ADOT) and the Arizona Game and Fish Department, which aims to reconnect animal habitats while cutting down on dangerous animal-related collisions.
These advancements have seen a temporary re-routing, redirecting the northbound I-17 lanes, as workers busily secure the critical infrastructure needed for the overpass; meanwhile, the southbound traffic remains closed until the installation of an additional 13 girders is completed, something the crews are diligently preparing for. This shift in traffic, although a temporary measure, will be in place until Aug. 28, and those traversing through the stretch between Munds Park and Flagstaff are cautioned by ADOT to expect delays and allocate extra time for travel, particularly during the buzzing weekend afternoons, as per the happenings documented by ADOT.
The ambitious wildlife overpass on Interstate 17 is scheduled for completion in fall 2026 and is part of a collaborative project between the Arizona Department of Transportation (ADOT) and the Arizona Game and Fish Department. The overpass is designed to allow deer, elk, and other wildlife to safely cross the highway, reducing the risk of animal-vehicle collisions and reconnecting fragmented habitats. ADOT officials say the project reflects the department’s commitment to environmental stewardship while maintaining traffic safety.
