After the Cervidae Peak Wildlife Overpass near Boise lowered wildlife-vehicle collisions by more than 80%, Idaho lawmakers have passed a resolution to advocate for more wildlife crossings to protect animals and improve road safety.
- Overpass reduces collisions by 80%+ near Boise
- $150 million annual cost of crashes could drop
- Legislature supports expanded crossing projects
What happened
Idaho’s Cervidae Peak Wildlife Overpass, built over busy Highway 21, has successfully lowered wildlife-vehicle collisions in the region by over 80%. Designed with natural terrain, vegetation, and fencing, it helps elk, mule deer, pronghorn, and other animals safely traverse a critical migration corridor. This overpass is a pioneering structure demonstrating how thoughtful engineering can reconcile the needs of wildlife and motorists.
Following this success, Idaho’s legislature passed Senate Concurrent Resolution 124, endorsing wildlife crossings statewide. The resolution encourages investment in overpasses, underpasses, and fencing systems to improve safety and reconnect fragmented habitats across the state’s highways.
Why it feels good
The reduction in collisions not only protects animals and drivers but also has a meaningful economic impact. Idaho currently faces over a thousand wildlife-related crashes annually, costing roughly $150 million in damages, medical expenses, and emergency services. Wildlife crossings offer a practical solution that benefits public safety and conserves vital migration routes essential for species survival.
Beyond safety, these projects restore natural migration paths disrupted by roadways. By reconnecting habitats, wildlife crossings support ecosystems and biodiversity. Idaho’s commitment signals a growing regional trend to prioritize coexistence between infrastructure and nature, reflecting increased awareness about the value of protecting wildlife corridors as development expands.
What to enjoy or watch next
The Idaho resolution is expected to encourage additional wildlife crossing projects across the state, potentially unlocking federal funding and fostering collaboration among transportation planners, wildlife managers, and communities. This momentum parallels similar efforts seen in other western states and places like Banff National Park in Canada, where fencing and crossings have drastically cut collisions and preserved habitat connectivity.
Environmental groups continue to advocate for nationwide expansion of crossing infrastructure, emphasizing the lifesaving and conservation benefits. Supporters and citizens can keep an eye on upcoming projects and legislative moves, as Idaho’s growing network of crossings offers a hopeful example of solutions that protect both people and wildlife.
