I was just thinking about this and I'm not sure if this situation ever exists because it seems really counter intuitive, but I figure in the entire country there's certainly at least one instance of it:
Are there any instances where a route runs concurrent with a bannered version of itself? For instance, maybe US-24 runs concurrent with US-24 Business or US-24 Alternate in whatever city, Kansas.
I realize this would defeat the purpose of the bannered route and I suspect if this situation exists somewhere it probably doesn't have AASHTO approval.
Does anybody know of where this might exist? It's particularly interesting if it's signed.
I think there's a US 41/41A concurrency in Nashville.

Correct, along 8th Avenue. There's also a US 70/US 70S concurrency along Broadway, though I don't know if that fits the scope of the thread.
North Carolina has several instances of fully bannered Truck routes concurrent with the main line routes. US 64 and US 70 Truck around Morganton NC are two examples. I surmise that a municipality can create truck restrictions that apply to all routes not bannered as truck routes.
Truck routes are usually where this happens, because some towns/counties/states don't realize that the TRUCK banner isn't supposed to be used for "all trucks stay on this road". (I.e. TRUCK US 40 should not be used on mainline US 40 just because 40 is OK for trucks.) MA 1A/US 1 multiplex a couple of times in Mass, the shortest one (near NH) being the signed one. RI 1A and US 1 also run concurrent, but never signed to my knowledge. But those aren't quite the same as what you're looking for.
