    Roadkill harms animals, endangers drivers, and costs billions of dollars every year. In Banff National Park in Alberta, Canada, wildlife scientist Tony Clevenger and other researchers have proven that constructing overpasses and underpasses for animals decreases roadkill and improves ecological connectivity. Many animals, including deer, elk, grizzlies, moose, lynx, cougars and others, have been recorded using the structures. Although animal crossing structures have been fairly common in Europe for a few decades, there are relatively few in North America. In The United States, the crossing structures that have been built, in places like Washington State and Wyoming, were partly inspired by the research Clevenger conducted in Banff. To create even more of them, Clevenger worked with a team of experts, including ecologist Nina-Marie Lister, to organize a design competition. The competition, named ARC solutions, was held in order to generate more cost-effective crossing designs that are also sustainable and environmentally friendly. The competition generated many new models for animal crossings and Clevenger and Lister hope that highway planners will adjust their approach to structure design based on them.

    Guess what, federal government doesn’t pay for state roads. States do.

    In Australia we have heaps of these small net "bridges" over highways designed to let possums cross without touching the ground

    What about if we build more of these wildlife crossings instead of funding wars, just a thought you know

    Wouldn’t it be cheaper to just make the road arch like a false bridge and the animals would use the area underneath to cross over?

    Um I pass through an “arc” all the time when passing through Nevada mountain ranges it’s actually quite common here since we have so many wild horses n deers causing crashes so yeah

    Since this video Colorado has built multiple of these crossings. I’ve seen a few of them not sure if they were the specific design mentioned in the video though.

    Im not sure exactly how all that government tax stuff works, but should the people get to take votes on what things to spend at least a portion of our tax money on?

    As a resident of Washington state, I did not know there was an animal road crossing here but that makes me very happy.

    The problem is that they put all the deer crossings on the busiest roads in the US. Why can’t they just put them on less busy roads?
