Before 1963, hungry squirrels in Longview, Washington, had to leave their park and run across Olympia Way to collect nuts near a local office building. After seeing many of them killed, resident Amos Peters built a dedicated 60-foot bridge above the road.

It’s now listed on the National Register of Historic Places.
