Great American Infrastructure: Wildlife Crossings

Posted by Steve Anderson on Friday, October 12th, 2012

This is the twenty-fourth in a series of entries celebrating infrastructure achievements in the United States.

What: Our responsibilities to the natural and built environments converge in wildlife crossings which are sprouting up all over the United States, making sure infrastructure serves not only people, but also animals.

When:  The first documented wildlife crossings were built in the 1950’s, but there are already thousands of crossings across the US.


Interesting facts:  It can sometimes take years for animals to adapt to using wildlife crossings, but studies indicate that if correctly placed, they have a strong impact on animal deaths on highways.

Any animal not traveling on four wheels can use the wildlife crossings, and they can serve as pedestrian alternatives for highway crossing too!

ARC (Animal Road Crossing) held a competition in 2010 to develop concept designs for a wildlife crossing structure at Colorado’s West Vail Pass along I-70.
