i’m pretty sure it’s done i didn’t see any constuction this past summer. u will spend a bunch so bring plenty with u. if u’ve got time go see the hoover dam– an hour away and if u’ve got 2 extra days go see the Grand Canyon, it’s about 6 hours from LV and worth the trip. Stay in Williams , AZ beautiful little town at the heart of TGC. It will literally take ur breath away at 1st sight.
good luck and have fun.
