Idle 1969 Idaho overpass transformed into wildlife crossing in 2025
An abandoned 1969 bridge over I-90 near Osburn, Idaho, was retrofitted in 2025 to serve as a wildlife crossing after decades of disuse.
Constructed in 1969, a concrete overpass spanning Interstate 90 and the South Fork Coeur d'Alene River near Osburn stood idle for over 50 years after mining interests blocked its intended road use. Truck driver Carl Wilson, witnessing frequent wildlife-vehicle collisions in the area, advocated for repurposing the bridge as a wildlife crossing. His efforts attracted support from local officials, conservation groups, the Idaho Department of Fish and Game and the National Fish and Wildlife Foundation, with the Idaho Department of Transportation providing permits and funding assistance.
The bridge opened for wildlife in the summer of 2025, and cameras have recorded deer and elk using the crossing, while funnel fencing directs animals away from traffic. Although the bridge will be removed in 2032 due to its limited lifespan, it currently offers a temporary solution that improves safety for both animals and drivers.
Why it matters
It shows how repurposing existing infrastructure can reduce wildlife deaths and enhance road safety.
