These will support the new road around Hoover dam when the road is complete. This shot was taken in January of 2008. By now the road might be up there. An awesome construction project.
As I'm looking at it, I can imagine myself taking this shot. I'm heading to Vegas in Aug 09, when my husband comes back from his deployment and that's one of the places we'll visit. I'll have to remember to get a shot while there to compare with yours. :)
