A major milestone for wildlife in California! 📷🦌

These deer are the first ever to successfully cross a roadway in the state of California using a newly constructed wildlife overcrossing, located on U.S. 97 in Siskiyou County, just 15 hours after crews wrapped up work for the day.

While the contractor is still completing final touches, it’s incredible to see wildlife already embracing the new structure, even with workers still in the area. In addition to deer, a bobcat and other wildlife have also been spotted using it.

This wildlife overcrossing was designed to provide animals with a safer way to cross the highway while helping reduce wildlife-vehicle collisions for motorists traveling through the corridor.

Seeing animals use the structure this quickly is an exciting sign of the positive impact this project will have for both wildlife connectivity and public safety for years to come
