In Vegas, you might have a hard time finding new towers on that side of town as fast as Vegas is growing in that area. I'm looking too, but not seeing anything yet.
Edit: This area isn't changed on Google Maps yet as this was part of the conversion of US 95 to a complete Freeway from I-15 to the Mount Charleston turnoff. My best guess on the actual tower location could be on the Storage One building in the area. If I get up to that area in the near future before you get official confirmation of the site, then I will let you know.
