The U.S. is home to more than 1,000 wildlife crossings. Such corridors are designed to connect habitats that have been divided by roads, allowing animals to more easily migrate and find food, water, and mates.
In the U.S., hundreds of these pathways are in Western states, where many migratory animals, such as pronghorn antelope and mule deer, live. But the crossings are helping animals across the nation. In Florida, such pathways help protect endangered panthers—as well as alligators, bears, and other wildlife. In Vermont, crossings allow frogs and salamanders to safely travel each spring to breed.
Research shows wildlife crossings can be very successful. Indeed, one study in Colorado found that installing crossings and related protection measures led to a whopping 90 percent decrease in collisions with animals including elk, black bears, and moose.
