Wildlife-sensitive Design

Wildlife-sensitive design seeks to protect animals while helping to reduce animal-vehicle conflicts. This type of design makes use of bridge-like structures (overpasses), culvert-like structures (underpasses), barriers, and escape structures. Barriers block animal crossings, while escape structures encourage animals to exit the roadway.
