Millions of animal-car collisions occur throughout the world each year. Many areas are trying out a new solution—wildlife passages. These crossings are designed to guide animals safely to the other side of busy roads. 

Some crossings are built as tunnels that pass beneath highways. They allow animals of all sizes, from elephants to turtles, to cross. Other crossings look like regular bridges, but they’re covered with grass and native plants. So far, wildlife crossings have reduced animal-car collisions by up to 95 percent.
