In Vegas, we call it the Spaghetti Bowl

[Vegasrider]

Where I-15 & Hwy 93 & 95 meet plus add in a few surface street exits too and you create a nice mess.  I don't know what the F you call where I-80 & 580/Hwy 395 intersect plus add in some surface street exits along the way and essentially you have Spaghetti Bowl # 2! Didn't expect to see that in this small city.
