Wildlife Escape Measures
The wildlife escape measures listed below are designed to allow animals to escape from getting caught within existing roadway fenced corridors. In this way, these measures will help reduce wildlife-vehicle collisions and sustain existing wildlife connectivity patterns of movement in the state. Details A through F, which are explained the Description of Wildlife Escape Measures text, are engineering drawings to help the project manager include the appropriate wildlife escape measure during final design.

Wildlife Funnel Fencing
Fencing that serves to funnel wildlife toward passage structures is critical to promoting highway passage. The wildlife measures listed below are suggested fencing to funnel wildlife across highway corridors with the aim of reducing wildlife-vehicle collisions. Details A through H, which are explained in the Wildlife Funnel Fencing text, are engineering drawings to help the project manager include the appropriate wildlife funneling measure during final design.
