These three maps below show which areas along each road is most suitable for wildlife crossings. Two factors were taken into account: landcover and slope. Analyzing landcover allows us to see which areas are more dense with vegetation (wildlife) while slope allows us to see which area would be flatter (least costly to build a wildlife crossing). These are both placed in a one mile buffer around each highway. Not only does this allow us to see what bridges could be built around each road but also the amount of vegetation near each road, which can hint where wildlife is and where they need to cross. Overall, areas that are away from urbanization are most suitable for a wildlife crossing site.
