Putting a highway in a national park created a barrier for many of the animals who want to go from point A to point B by crossing the road. For others,it was life and death situation when they decided to cross the highway. By putting a fence on either side of the highway, they reduced the carnage considerably, but it slowed the movement of animals, if not completely stopping it. As result underpasses and overpasses were built, trying to overcome the highway as a barrier, and moving toward more of a natural environment. Many creatures have become used to having the fence in the park and learned to navigate it, other rest on it as they wait for the parents to bring back food and shove it down their mouth.
Until next moment,
