As highways continue to fragment natural landscapes, wildlife overpasses, such as this proposed design in West Vail, Colorado, are an innovative way to maintain habitat connectivity and allow safe wildlife movement. These overpasses prove to significantly reduce collisions between cars and wildlife, such as in Banff National Park in Alberta, Canada where wildlife under- and overpasses have reduced wildlife factalities by 80 percent (FHWA, 2011). It is important to consider how to reduce the negative effects of habitat fragmentation when examining road development in order to protect both wildlife and drivers.
