We passed through the city of Longview, Washington, on our recent family trip, and my wife noticed that the town is famous for the "Nutty Narrows Bridge," a bridge built solely for squirrels.
In 1963, resident Amos Peters decided that there were too many squirrels flattened by cars when running across the street to the park, so he built a mini-suspension bridge to keep the squirrels safe. A local councilwoman named it the "Nutty Narrows Bridge" after the state's Tacoma Narrows Bridge, and the name stuck.
To date, the Nutty Narrows Bridge has the title of the World's Narrowest Bridge and also the World's Narrowest Animal Crossing. It was also the world's first bridge built just for squirrels!
