I found it odd for Boone, NC to have 3 US routes from the same parent in its town. US Routes 221, 321, and 421 are all in there. Can anyone find similar cases of this or is this actually not abnormal?
I feel like somewhere in SC has three x01s. I guessed Conway, and looked it up. nope, only 501 and 701. 601 starts off 301 somewhat to the west in Bamberg.
in general, though, how about South Carolina having all the x01s from 301 to 701, as well as the parent route, 1? that's all but one child (101 doesn't count for the purposes of this discussion).
does any state have all the child routes and the parent for any non-trivial amount of children? Penna has all the 22s. the original 122 (NJ/DE) was decommissioned and a new 122 was commissioned in PA, so I think PA comes closest, with six x22s and the parent.
At one time, all three US routes in Boone met in downtown, but that's no longer the case since US 221 was routed onto a bypass. However, truck routes for all three US routes do intersect.
As for child and parent routes interacting, US 60 spawns US 460 in Frankfort, Ky. They meet and run concurrently for one block in downtown Mt. Sterling (and it's a wrong-way concurrency, with eastbound 60 being westbound 460, and vice-versa). Then US 460 ends at US 60 in Norfolk, Va.
US 64/264 multiplexes in Raleigh then meets back up in Dare County
US 78 and US 278 in GA meet and concur twice.
US 41 and its child US 341 meet twice in GA where the child is only in GA anyway.

What is so strange about this?
Also, when the US 421 Bypass is built, US 221, US 321 and US 421 will likely no longer go through Boone, leaving likely business routes behind.

Before 460 was truncated at Frankfort, did it piggyback 60 all the way to Louisville, or did it take an alternate route?
Yes, followed 60 to Louisville.
0For Interstate routes (with * denoting unsigned routes):

I-595 in FL is not in Miami. That connects in Fort Lauderdale which even though are in South Florida, I do not think it qualifies as one city per OP.
Anyway, I do not think that it is common for one city itself to have three to answer the original question. Metro areas and regions and US highways in a specific area are very well are though.
In the same vein, Reply #8 mentions Hampton Roads. It looks like two different cities each have three 3dis with the same parent. Norfolk contains three of the four listed: 264, 464, and 564. Chesapeake has 264, 464, and 664. None of the other cities in the area have multiple I-x64 child routes, unless I've forgotten something.
CA-160, CA-275, and CA-244 are spur routes in Sacramento, CA.
