Road ecology blog: Multifunctional underpass for desert bighorn sheep, Nevada, USA
Road ecology blog: Multifunctional underpass for desert bighorn sheep, Nevada, USA.
This is a very complex set of mitigation measures. In the foreground of the first image is Hwy 270 with a wildlife guard to discourage ungulates from entering the road section that goes under the bridge. The fencing leads the ungulates to a narrow at grade crossing opportunity across the off-ramp for US Hwy 93 with two wildlife guards (one on each side). The second image shows a close-up of that situation. Additional wildlife fencing guides the animals under the underpass and keeps the animals physically separated from traffic under the bridge.
