As population continues to increase in size, we inevitably find ourselves encroaching more and more on the delicate habitats that support our animal neighbors. Unfortunately, most of the time not much is done to accommodate our fellow creatures, which can often lead to tragic results.

The town of Longview, Washington, discovered this back in 1963, when the squirrel population was having trouble crossing a few newly built roads. So they came up with a brilliantly simple idea of how they could help their little bushy-tailed buddies without disrupting the daily commute.

After witnessing a few-too-many squirrels lose their lives trying to cross the busy Olympia Way, Amos J. Peters, an owner of a construction contracting firm, devised the Nutty Narrows Bridge.
