I forget which state senator it was, but someone in the early 2000's here was wanting to relabel 240 in OKC because there's another 240 somewhere else in the country and he felt there should only be one.
Meh.

You could keep all kinds of different numbers and just put up some signs that call it the "OKC Loop" or whatever semi-creative thing a committee comes up with. It's just signage and means nothing. It's not actually a loop anyway. A true loop is continuous. This is a collection of road changes/exits/onramps. So again....meh.
