7 Amazing Overpasses for Animals

7 Amazing Overpasses for Animals

Wildlife overpasses, green bridges, and ecoducts all refer to structures that have been built over roads to allow wildlife to cross safely to the other side of the road. The bridges are for the animals; the animals walk over the road, and the vehicles go through the structure. Most of the structures are between 10 m (30 ft) and 60 m (180 ft) wide. They typically have soil, litter, and vegetation on top to provide suitable habitat for a range of different species and species groups. The larger structures are typically intended for large mammals ranging from ungulates (e.g. deer, elk, moose) to large carnivores (e.g. black bear, grizzly bear, Canada lynx, wolverine, wolf). Here are pictures of some of the most beautiful and interesting wildlife overpasses in the world. — Marcel Huijser

Wildlife Overpass, Banff National Park, Alberta, Canada. In Banff National Park, there are currently 41 wildlife crossing structures (6 overpasses and 35 underpasses) that help wildlife safely cross the busy Trans-Canada Highway. Since monitoring began in 1996, 11 species of large mammals—including bears, elk and cougar—have used crossing structures more than 200,000 times.

Neat. Good thinking for the animals when so many want to get rid of them.

The crabs are really weird! I wish they had more overpasses/tunnels for wildlife.

Cool! I wish there were more around the globe.

Such a marvellous and splendid idea, this must be expanded to many other places and give wildlife a chance to survive. Wonderful alternatives to concrete road ways ensuring the survival of many wildlife that may well have otherwise been killed.

Oh wow! That is so wonderful! There is hope for our species after all!!

I believe that more tax dollars should go to compassionate programs like the overpasses. In New York City, 24 million dollars of tax payer money will go towards replacing new street signs with, newer street signs. The new, new street signs will be different; they will have ALL CAPS. The reason given - it makes the streets seem more authoritative. 24 million to replace nice signs with new ones, for authority. That's one example, of many, of how tax dollars are blatantly misused. I don't have all the answers but I'm thinking it's reasonable to keep the street signs the same and spend the money on animal crossings.
