Under Construction

Wildlife crossings have been built all over the world. In the U.S., they have been built in Arizona, Utah, and Wyoming. There is also a major project in Washington State. Garvey-Darda is working on this project. She’s helping to design about 20 wildlife crossings. They are expected to be completed by 2029.

Garvey-Darda says these crossings have made a big difference. “We now have close to 5,000 deer and elk going through the undercrossings,” she told TIME for Kids. “All of these animals were potential accidents.”

How will animals know where to cross? Plants can be grown on wildlife bridges. The plants will attract the animals. Then the animals will cross in safety.
