It is hard to get a sense of scale from this photo until you realize that Hoover Dam is one of the largest structures in the world and the shadow is the bridge now built high above the dam across the Canyon. If you click on the picture and expand you screen you can just make out the cars on the left side of the dam, parked by the cliff going down to the Colorado River. The name of the bridge is the Mike O'Callaghan – Pat Tillman Memorial Bridge. It is 840 feet above the river, the second highest in the U.S. and has the longest concrete arch in the Western Hemisphere. I you keep up with bridges, dams and other such projects, you will know that the U.S. is not particularly known for extreme engineering in this category. It is nice to have something like this virtually in my "backyard." (I consider Arizona to be my backyard).
