Theme 5: Why Did the Chicken Cross the Road?
All highways run through animal habitats. Fencing highways can provide drivers some protection from animal-related accidents, but they fragment the habitat, causing problems for wildlife. In this activity, students learn some of the reasons that animals will attempt to cross highways.

Theme 5: Why Did the Chicken Cross the Road?
Animal passages for wildlife are becoming more prevalent. Their purpose is to provide a safe path for animals to cross man-made barriers, in this case roadways. Fish ladders, patented in 1837, are an early example of this type of intervention. In addition, passages provide animal access to resources on the other side of the barrier. Crossings help to connect habitats to avoid habitat fragmentation, which can restrict the gene pool resulting in lower and more at-risk populations, as well as potential extinction. Vehicle and wildlife collisions account for many injuries and deaths for humans and other animals, property damage, and …

Theme 5: Why Did the Chicken Cross the Road?
More factors than previously mentioned must be considered in the design of an animal crossing structure, such as temperature, precipitation, vehicle traffic, noise, and vehicle exhaust. Consideration of these environmental factors and events will require modifications to the original design. This is a common practice in engineering. The original design might go through several revisions as modeling, testing, and experience reveal the need for modifications.
