Question about riding in Las Vegas

I was hoping someone could help me find a suitable location to do intervals in the mornings in Las Vegas. I have a good 35-40km that goes up the strip then heads west, it’s fine for a tempo ride, but not great for doing intervals (other than sprinting light to light). I’m looking for advice on a loop, like a crit course, 3-5km in an industrial park or residential area, preferably without stop lights/signs. Anyone got some good ideas, ideally 10km or less from the strip. :us:
