In Boone NC, US 221, 321, and 421 all go through town. 321 and 421 run concurrent north out of town. 221 and 321 run concurrent south out of town, and 221 and 421 run concurrent east out of town, with 221 signed North and 421 signed South. Also in Raleigh, US 64 and 264 run together from I-440 to Zebulon. This is interesting because 264 ends at I-440, with 64 continuing on. Any other examples like this?
Also, fun fact: I believe Boone, NC is the only place in the country where 3 sibling routes meet each other. There even used to be an intersection where 221, 321, and 421 all met, but that changed when a new alignment was built for 221
US 30/130 in Camden/Collingswood NJ is a notable one.
MA 2/2A (signed), 1/1A (once signed and once unsigned), 3/3A (unsigned)
- US 231/431 from Huntsville, AL to Fayetteville, TN
- US 41/441 from High Springs to Lake City, FL
- US 1/301 near the FL/GA border
- US 301/501 near the SC/NC border
- US 1/501 in Sanford, NC
- US 78/278 twice: once in Atlanta and again in Augusta, GA (did it ever also happen in AL before I-22 was built?)
US 41/141 from Green Bay to Abrams.

US 41/141 from Green Bay to Abrams.
US 41 has another US 441 from Lake City to High Springs in Florida.
If we expand this to include Interstate routes, there are a couple:
- I-94/694 northwest of Minneapolis, MN
- I-95/495 on the east side of the (DC) Capitol Beltway
Some others:
- Another US 1/US 301 in central Virginia (basically from Petersburg to Richmond)
- US 1/US 401 north of Raleigh, NC (surprised Eth didn't catch this one)
- US 58/US 258 near Franklin, VA
- US 158/US 258 near Murfreesboro, NC
- US 69/US 169 in suburban Kansas City, KS (along with I-35 for part of it)
- US 10/MN 210 in central Minnesota (210 was numbered deliberately as a child of US 10, and east of the concurrency was a U.S. route until 1973)
Quote from: Eth- US 78/278 twice: once in Atlanta and again in Augusta, GA (did it ever also happen in AL before I-22 was built?)
Yes, between Guin and Hamilton. US 43 was also part of that concurrency to complete the triplex. IIRC, this remained until Corridor X was finished between Exit 16 (south side of Hamilton) and Exit 52 (east of Carbon Hill) sometime in the early 2000s. I distinctly remember it existing (and Corridor X not completed there) when I was stationed in Meridian, MS from 1998-2001.
I-87/I-287 in New York. US 22 / 322 / 422 in PA and Ohio, though only 22 is signed, so it can be analyzed as separate 322s and 422s (though that would mean the former occurs twice in the same state)

Outside of Lewistown PA, if US 422 were signed on it's implied concurrency, there would be a very short US 22 / US 322 / US 422 / US 522 concurrency.
Here in N. Calif. we've got the I-80/I-580 reverse concurrency (EB 80/WB 580 and vice-versa) between the Bay Bridge distribution (with I-880) interchange at Emeryville/W. Oakland and Albany, where they diverge. Approximately 5 miles in length.
in Michigan, was there a Concurrency of US-12 and US-112 where US-112 was routed around the Ann Arbor/Ypsilanti area with US-12 on what is now I-94 in the 1950s?
US 71 and US 371 for a mile or two in Coushatta, LA.
US 67 and US 167 through Little Rock and north-central Arkansas
US 60 and US 160 in Springfield, MO
US 18 and US 218 near Charles City, IA
A former one: I-440 and I-40 around the south side of Raleigh (I-440 has since been truncated).

You're correct about 422 (there is some evidence (https://www.aaroads.com/forum/index.php?topic=15227.msg2056231#msg2056231) suggesting that PennDOT internally considers 422 to be continuous, but it's not signed that way).
But the 22 - 322 overlap is visibly signed for both.

A few that come to mind...
- US 9 and NY 9N through Lake George Village, NY
- US 3 and NH 3A share a wrong-way concurrency in Manchester, NH
US 89 and 189 from downtown Jackson south to the split on the Snake and Hobeck River in Wyoming. Completely weird multiplex that makes zero sense when you think about:
http://www.usends.com/189.html
Former: I-40 and 540 near Fort Smith, Arkansas.
US-360/460 in Burkeville, VA
US 21/321 in Cayce, SC
US 27 and US 127 on Central Parkway in Cincinnati.
US 1/301 in Virginia.
US 301/501 across the NC-SC Line.
US 41/ US 41 ALT in Nashville.
US 9/ NY 9N in Elizabethtown, NY
US 231/431 in AL
US 31/431 in Nashville
US 6/106 now defunct in PA
Some other defunct parent/child multiplexes:
- US 399 met US 99 south of the city of Bakersfield and multiplexed in to the city.
- US 66 and 666 were concurrent from Sanders, AZ to Gallup, NM.
- US 60 and US 260 were concurrent for a couple miles near Springerville, AZ. Oddly US 60 and AZ 260 are now concurrent west of Springerville in the City of Show Low despite the new 260 having nothing to do with the previous US Route.
NJ tries to encourage this parent and sibling to work together, even though it's truly just the parent route.
https://goo.gl/maps/QR82q3jVmH42
(Technical note - NJDOT doesn't always do this parent/sibling numbering on state routes, although in cases like this its apparent that was the goal here)
US 80/280 - wrong-way in Phenix City, AL
Lots of concurrencies of US 1 and its children in NC.
Two separate concurrencies of US 1/501 (with US 15) in Sanford NC and Aberdeen NC.
US 401/501 (with US 15) in Laurinburg NC.
Two separate concurrencies of US 1/401 north of Raleigh and from Norlina NC to I 85, where US 401 ends.
US 301/501 crossing the NC/SC border.
And lest we forget, the reverse concurrency of US 77 and US 177 -- themselves concurrent with US 60 -- between Tonkawa and Ponca City, OK. One of two such "place shifting" concurrencies in that state, but the only one to feature parent & sibling designations (the other is 60/64/81 near Enid).

Or NJ 347 ends northbound at CR 670.
US 60/US 460 -- 460's western terminus is at US 60 in Frankfort. In Mt. Sterling, they have a one-block wrong-way concurrency (East 460 is on West 60, and vice versa.) Then US 460 terminates at US 60 in Norfolk, Va.
US 50 and US 150 have a concurrency in Indiana.

NY 14 and 414 overlap in Watkins Glen
NY 14 is (probably) not NY 414's parent.
NY 414 started out as NY 44, and got renumbered when US 44 was created. Apparently they decided the easiest thing to do was to send out a guy with a can of black paint and put 1's between the 4's.
Maybe there was some intent to make a reference to NY 14, but more likely it's just a coincidence.
US 92 and US 192 are mulitplexed for a coupled blocks on Vine Street in downtown Kissimmee, FL.
US 223 joins US 23 for it's last few miles into Ohio.
US 9 in New York might be the poster child for these things. Two concurrencies with NY 9A and two with NY 9N.
This is probably a stretch, but I'd say NY-265 and NY-266.

And the 43/78/278 triplex in Alabama involved a wrong-way concurrency. NB 43 was routed with WB 78 and EB 278.
I'm surprised that no one has mentioned I-85 and I-285 on the SW side of Atlanta. Until they were rebuilt in the '80's, the two routes actually shared the same pavement.

That's an oddity for a couple reasons.The length isn't particularly clear. Some signage says it's for 1 exit, other signage says 2 exits. I've seen some things that have no WB concurrency, routing 17M straight onto US 6. The concurrency wouldn't even exist if the US 6 WB slip ramp wasn't there.

One I don't think was mentioned yet is US 63 and IA 163. IA 163 got its number for previously being US 163, but Iowa decided to extend 163 several years ago, making the Des Moines to Burlington expressway one number, and creating the overlap with US 63 between Oskaloosa and Ottumwa.

Oops, thought the 3rd page was the first page. No idea how that happened.
IN-550 either has a gap, or is an unsigned concurrency with US 150 (and partially with US 50) between Loogootee and Wheatland
The Wiki article for IN-550 claims it is gapped, and not an unsigned concurrency. But that is good old Wikipedia for ya

Indiana's gaps really are gaps. There are at least three flavors of IN 101.
Maybe...US 24 Business and US 224, for 1 Block in each direction along Park Dr in Huntington, IN, although looking at Streetview, this may not be a signed US 24 Business route, but Google has it ID'd as such

Even if so, does not Business 24 count as a child of 24 as well, making 224 and Business 24, siblings? Maybe step-siblings?
It may be a Google Maps error -- there is no signage for Business 24 at either end of its route on Google Maps -- US 24 is routed onto what Google describes as "US 24 Bypass"/Huntington Bypass, by the signage seen on Streetview

Indiana's gaps really are gaps. There are at least three flavors of IN 101.
I'm assuming Indiana uses the same number for different sections of highway is because of the way the highways are numbered in Indiana. Indiana's state highways are setup the same way the U.S. highways are going across the country with the even numbers going east and west and the higher numbers being in the south and the same for north-south and the higher numbers being in the west. There are some exceptions though and those are the diagonal routes SH 37, SH 47, SH 56, SH 57, SH 62, and SH 67.
