How’d the Bighorn Sheep Cross the Road?
The bighorn sheep population in northwest Arizona is important to outdoor enthusiasts of all types, yet highways have separated this population. As a result, wildlife-vehicle collisions, interference with access to adequate water and lack of habitat connectivity disrupt bighorn and put their population health at risk.
In a historic and innovative collaboration with the U.S. Fish and Wildlife Service, Federal Highway Administration, and the Arizona Department of Transportation, the Arizona Game and Fish Department created a solution that saves the lives of bighorn sheep and people. To alleviate vehicle collisions with bighorn sheep along a busy 15-mile stretch of Highway 93 north of Kingman, three wildlife overpasses and adjacent funnel fencing were constructed. This infrastructure allows wildlife to cross over the road safely, helping to keep populations connected to their habitat and reducing risk for motorists and wildlife.
