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.

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.

Crossing Structure Handbook
This handbook provides technical guidance and best management
practices on the planning and design of wildlife crossing mitigation
measures; for transportation and other stakeholder agencies.
- Arizona's
Wildlife Linkages
These ADOT Web pages, which includes a handy map, should be used
to determine if the proposed roadway improvement project has any
identified wildlife linkages within the project limits.
- Adobe Reader
Documents are posted as they become available in PDF format, which
requires Adobe Reader to view.
