If I had to guess, they were blocking hundreds of people not going to Burning Man. You can't pop onto another road or take a detour in the Southwest, so often times, there will be only one road that goes to EVERYTHING, and if it's blocked off, you'll have to drive three hours just to get on the alternative route.
