On US 93 North along the 56 mile stretch of highway, there are:
- 41 fish and wildlife-crossing structures
- 60 jumpouts
- 18 miles of fencing
- 8.7 miles of road length with fencing on both sides
The crossing structures were placed in areas that have a history of wildlife crossings and wildlife mortality, and/or locations where the surrounding landscape and land use was best suited for the crossing structures. Structures were typically located at stream crossings and areas with protected habitat on both sides of the road.
Part of the success of wildlife crossing structures comes from animals having a sense of security while approaching or crossing through the structures. We appreciate your enthusiasm, but please do not enter the wildlife crossing structures!
Expansion Bridge 6 x 4 Concrete Box Culvert
Corrugated Metal Arch Culverts
Over eight miles of road with 8-foot high wildlife fencing on both sides keeps wildlife from entering the highway and directs them towards crossing structures.
Sixty “jump outs” allow wildlife to jump to the other side of the fence safely should they somehow be caught in the fenced road corridor.
Wildlife Crossing Guards
Wildlife crossing guards modeled after cattle guards or “Texas gates” discourage deer and other hoofed mammals from entering the fenced road corridor at access roads.
