Wildlife Connectivity

  • Wildlife Connectivity Guidance
    • This overview provides an introduction and background to wildlife escape measures, wildlife funnel fencing, and wildlife passage structures. This document also includes a case study on State Route 260.
  • 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.
