Wildlife overpass (west) for pronghorn (Antilocapra americana) (46 m (150 ft) wide), on the Path of the Pronghorn, Trapper’s Point, US Hwy 191, near Pinedale, Wyoming, USA.

The Trapper's Point area is a bottleneck in a 150 km (93 mi) long migration corridor of pronghorn between their winter habitat in the Upper Green River Basin and their summer habitat in Grand Teton National Park. This migration corridor is referred to as the "Path of the Pronghorn". The Wyoming Department of Transportation (WYDOT) constructed 8 wildlife crossing structures (2 overpasses ($2.5 million each) and 6 underpasses) and wildlife fencing (2.4 m (8 ft) tall) along a 21 km (13 mi) long highway section bisecting the migration corridor. The overpasses were designed for pronghorn, a species that is characteristic of open landscapes and that requires long sight distances. Over 90% of the pronghorn that use the 8 structures use the overpasses rather than the underpasses. Other large ungulates in the area are mule deer, elk and moose.

Road ecology blog: Double wide cattle guard to exclude wild ungulates from fenced road corridor, US Hwy 191, North of Daniel Jct, near Pinedale, Wyoming, USA.

Note that in North America escape ramps for small mammals, reptiles, and amphibians that have fallen into the pit under the metal bars or grate are often lacking while it is a standard feature for wildlife guards in western Europe.
