Some locations allow for underpasses to connect open spaces, while others require overpasses. Check out this cool overpass in Utah that is reducing collisions with wildlife and is being used by both predators and prey! This is an option here in California for retrofitting roadways where culverts, tunnels and underpasses don’t always work. In fact, scientists are working on an overpass at the 101 and Liberty Canyon, so the mountain lions there have room to roam and the species doesn’t die out due to inbreeding.
