Wildlife crossings — overpasses, underpasses, and culverts designed for animals — significantly reduce vehicle-wildlife collisions on major highways. Long-term monitoring of crossings in Banff National Park has documented declines of more than 80 percent in vehicle collisions with elk and deer along instrumented stretches of highway since the structures were installed.
