Road ecology blog: Wildlife overpass for desert bighorn sheep, US Hwy 93, NW Arizona, USA
Road ecology blog: Wildlife overpass designed for desert bighorn sheep (Ovis canadensis nelsoni), US Hwy 93, NW Arizona, USA.
This particular overpass is about 15 m wide and it is the most southern of three wildlife overpasses in the area. It is situated at a ridge; desert bighorn sheep seem to want to cross US Hwy 93 primarily at ridges rather than at flat terrain or gullies. Therefore, for desert bighorn sheep, overpasses seem more appropriate than underpasses.
