What a win! Installed in 2012, this wildlife crossing over Highway 191 in Wyoming provides safe passage for pronghorn, allowing them to make their ancient seasonal migration unharmed. According to the Wyoming Department of Transportation, wildlife-vehicle collisions here have been reduced by more than 85 percent by the crossing.

Fun fact: The pronghorn is the fastest land animal in North America and, depending on the scientist, the second- or third-fastest land animal in the world.
