​Wildlife Crossings 

Pennsylvania has a large network of roads that crisscross the state connecting our cities and towns. These roads create an obstacle between one part of a habitat to another. This is called habitat fragmentation. Wildlife cross the roads because they are looking for food, water, or they are running from a predator (including humans). Unfortunately, wild animals don't understand the dangers associated with roads and road traffic. One of the most significant threats to wildlife and the motoring public are collisions with and avoiding collisions with wildlife. 

One way to reduce wildlife-vehicle collisions are to install wildlife crossings that connect these habitats with safe passages across the roads. Wildlife crossings are tunnels and bridges built around highways and major traffic areas for animals to utilize. They provide a safe crossing over or under roads. Underpasses offer a way for wildlife that fear bridges to cross under the road safely. Smaller animals frequently use these types of crossings to avoid the dangers of the road above. Larger overpasses are vegetated crossings that blend into the surrounding area and where it is impractical to go under the roadway.
