Governments across North America keep building and expanding roads. This can have deadly consequences for animals but, potentially, drivers too. One way to manage these risks is by building eco-passages, structures that help animals bypass barriers that humans create. This animal overpass near Burwash, Ont. is the first and - for now - only one of its kind in Ontario. In this episode of Living History, we'll get a close look at the Highway 69 animal bridge, learn about the impact it's been having and see other eco-passage styles that you might never notice.
