Utah built this animal overpass In 2018 and it's already getting a ton of use.
The $5 million bridge was designed to help wildlife cross a busy section of I-80 outside Salt Lake City. And in this video from the Utah Division of Wildlife Resources, you can see just how many different types of wildlife are making use of the bridge.
The video shows everything from moose, to dear, to elk, and even a bobcat carrying another animal in its mouth. Pretty awesome.
The overpass's location was chosen based on the migratory patterns of the animals.
