Road ecology blog: Wildlife underpass and overpass, US Hwy 93 on Flathead Indian Reservation

May 02, 2012  •  Leave a Comment

Most of the wildlife underpasses along US Hwy 93 on the Flathead Indian Reservation in Montana are elliptical metal culverts that are about 7 m wide and 4-5 m high. This particular wildlife underpass is located near Evaro and not only allows animals to pass safely underneath the highway, but there is also a stream that flows through the structure. The wildlife overpass is in the background. Both the underpasses and the overpass are used by a wide variety of species. More information, including images of animals using the structures can be found at the following websites:
