This undated artist's rendering from the Oregon Department of Transportation shows the design of an overpass crossing for wildlife spanning above four lanes of traffic on I-5, looking southwest. ODOT is expected to begin construction on the crossing in 2028 in the Cascade-Siskiyou National Monument, less than two miles north of the California border.

The Oregon Department of Fish and Wildlife estimates 14.5 million wild vertebrate animals are killed on Oregon’s roadways each year. Data shows it’s difficult to control driver behavior with things like road signs and traffic regulations. A more effective way to mitigate animal fatalities is by redirecting the animals themselves.
Wildlife crossings — human-made structures that allow animals to safely pass through habitats near roadways — have been a successful tool in preventing animal-motor fatalities. States like Montana, Colorado and California have over 100 wildlife crossings, while Oregon has only six.
