Bighorn sheep have already been photographed using a wildlife highway overpass in Arizona, south of Hoover Dam. The overpasses were completed in January.
Arizona Game and Fish officials were concerned when they heard that Highway 93, in northwest Arizona, was going to be widened. The area is home to the nation’s largest contiguous population of bighorn sheep. Experience had shown that big horn sheep are wary of wildlife underpasses, which are much more popular with the sheep’s predators. Since bighorn sheep like to stay high, and were approaching the highway from the ridgelines anyway, four overpasses were incorporated into the 15-mile-long highway expansion project.
