For the 7.5 million residents of Washington state, most, if not all, have used or will use I-90 at some point. This interstate connects the two largest cities in the state: Seattle to the west and Spokane to the east. It also runs right through the southern end of the North Cascade mountains, home to great populations of blacktail deer, Roosevelt elk, coyotes, and black bears, among other species. As you drive east from Seattle, you might notice a bridge with no roads connected to it that spans the interstate just before you get to the city of Easton. This bridge is a wildlife crossing that will help keep these animals safe from vehicles. The bridge is there thanks to a Seattle-based organization, Conservation Northwest, and is just one of many projects this organization has helped fund, design and implement in this region.
