Bridges here cross the myriad of Washes (natural drainage channels) that are everywhere in the Mojave Desert. Have a look at Google Earth or similar and note the spider-like legs or drainage channels that go in many directions from the mountain peaks. Las Vegas has mile upon mile of man-made (of course) drainage channels to help direct as much water away from homes and businesses. And of course, the Las Vegas Strip.
