I was just wondering which state has the most US route overlaps? I noticed that Georgia seems to have many small towns and cities that have two US route designations overlapping as well as long stretches of routes overlapping (US 1 and 23 for instance). Plus US 1 itself overlaps eight different other US routes in its 232 mile journey within the state. So I must say that the Peach State would be the winner here, but have not officially counted them all. I only came to the conclusion based on those two factors.
Plus Georgia you have to admit has more US routes per square mile than any other state including the big one's like NY and CA which is another factor to add.
I'd bet that by percentage of US Route mileage (but not by total US Route mileage), Wyoming has the most US route concurrencies.
I will say that Georgia does have a lot of US Route concurrencies, but I also have not counted every state, so Idk for certain if it's the winner. But GA has a lot, that's for sure.
Yes Corco that is true, but how many total?
If you drive through Georgia on all US routes you will be overlapped with other US routes no doubt just like Wyoming.
However does Wyoming have as many concurrencies in number as Georgia?
Add Arkansas to the list. I think every one of its US routes overlap at some point in the state.
Indiana might be a contender for a couple of reasons: It's a primarily PLSS-grid state, but there are still plenty of diagonal routes, some of which zigzag along east-west and north-south roads for long stretches rather than making a straight line from Point A to Point B (US 35 comes to mind). Also, as of late, INDOT has rerouted plenty of US highways around cities, creating more concurrencies than ever before. I'll crunch some numbers later.

Probably not. I'd bet the average concurrency length is longer though.
If you're going on pure quantity, this is probably a pretty boring thread subject, because I'm not sure how it could be anything other than Georgia or maybe Arkansas.

Perhaps you could try listing them all to add some spice to the thread? :-D

Problem is when you like photographing like I do, having a state like Georgia and Arkansas is perfect for taking pictures of assemblies. Of course you have Virginia and its many state routes and its long shield assemblies at route junctions that make good subjects on that, but I guess when you see that it makes it more interesting to wonder how.
I think the interesting thing is that it is too boring (unless your NE 2 who has all the time on his hands) to count every one of them, but at the same time curious as each state has its own personal way of aligning routes.
We already mentioned here quantity verses overall lengths which already made this topic fascinating so far. Plus I think we are coming up with more most of something than the OP that is related to the OP making this topic an interesting discussion.
^^You are gonna be disappointed going to Arkansas looking for assemblies. They DO NOT like to sign highway concurrencies. Finding such assemblies are an adventure all to itself.

Actually nothing surprises me anymore. Just like US 50 in Grand Junction, CO where it becomes almost non existent after it merges with US 6, where it should be signed like US 85 hundreds of miles to the east where concurrent with I-25 is not at all disappointing when I make it back to Arkansas.
I lived in New Jersey for half of my life that had few US route concurrencies so I can live LOL!

I found out that Indiana has 20 US routes and 33 concurrencies, making it 1.65 per route. The total mileage of US Routes in Indiana is 2826 miles, and about 8.8% of that (250 miles or so) is part of a concurrency. To prevent double- and triple-counting for mileage, I defined 2-, 3-, 4-, and 5-way concurrencies differently. I realize that this might have skewed the number of concurrencies a bit based on definition, but what else am I supposed to do with the mess around Indianapolis?
The 2 longest concurrencies are US 41/150 (55.83 miles) and US 50/150 (37.67 miles), which leads me to question why US 150 even exists north/west of Shoals, but that's another topic. The average length of a concurrency is 7.52 miles, but throwing out the US 150 concurrencies would make it 4.6 miles.
Ok, well, there's Indiana. What do the numbers look like for Georgia, Arkansas, and Wyoming?

But for the number of routes it has, I'd say it has a fair number... 1/9(/46), 30/130, 40/322, 202/206... I may be missing one or two, but even if I'm not, I think that leaves US 22 as the only one without a concurrency in the state.
Not sure how it ranks, but in Alabama all put two US routes have at least one concurrency with another US route. Also, eight routes have concurrencies with Interstate routes.

The only US routes in Kentucky that don't have concurrencies are 25E, 25W and (I think) 79. (I'm not sure if there is short concurrency where 79 crosses 41 or not; seems like I remember that intersection was going to be rebuilt.)
US 60 has a concurrency with every US route it intersects where the other route does not terminate.

US 60, 70, and 99 ran together from the San Bernardino Split (not the East Los Angeles Interchange, which didn't exist until the early 1960s) east to Pomona, and then again from Beaumont to Indio.
99 & 50 split in Stockton, not Tracy, with 50 following the old surface street alignment of Route 4 west, then southward along today's I-5 to Tracy.
The 6/66 combined segment was between 5 (99 at the time) and 101.

US Route 7 is concurrent with I-84 between Exits 3 and 4 in Danbury. It is also concurrent with US Route 6 and 202 on I-84 from Exits 4 to 7.
US Route 44 is concurrent with I-84 over the Bulkeley Bridge between Exit 50 in Hartford and Exit 53 in East Hartford. It also shares the road with US Route 6 in sections of Manchester and Bolton.

Some of the US 44 overlaps.

There was a historical 5/6 overlap across the Charter Oak Bridge from 1942 to c. 1970.

Plus Georgia you have to admit has more US routes per square mile than any other state including the big one's like NY and CA which is another factor to add.
Speaking of California, I believe we are the state with the *least* number of US route concurrencies... ZERO! We only have
5 6 7 US routes (6, 50,
95,
97, 101, 199 and 395) and only 2 cases where two US routes intersect (101-199 and 395-6).
Edit 1: Oops, forgot about US 97 :banghead:
Edit 2: Oops again, forgot about US 95 :banghead: :banghead:
^^ Hawaii and Alaska too, but not anywhere near as impressive...
The two examples of 'big states', New York and California, have never been fans of the US highway system, instead going with sparse networks (though CA had a fairly extensive network before the Interstates came), plus if you are doing per sq mi, then a bigger state is already at a disadvantage even if the big state has lots of US highways.

Georgia may very likely be the winner, here. :)
Thanks for the research!
If you include secondary routes, such as state routes (GA 121), Georgia will be the clear winner.
In Massachusetts, there is only one US route overlap: the short US-20/US-202 overlap in Westfield.
In fact, in eastern Mass, many of the US routes (US-1, US-3, US-6, US-44) never even touch another US route.
The only US route intersections in the state are in the western part: 20/202 in Westfield, 5/20 in West Springfield, and 5/202 in Holyoke.

In addition to the significant 7-20 overlap in the Berkshires, we have 5 and 202. They don't just cross in Holyoke, they overlap, at least SB. This is in front of Nick's Nest:

[Facepalm] My bad. I don't know why I always seem to forget US-7. Used to travel that overlap several times a year, too.
I havn't been through Holyoke in a long time, but is the 5/202 overlap only for SB 202? I seem to remember NB 202 just crossing 5.

I also haven't been through in a few years, at least, but when I used to travel that way regularly, US 202 NB did in fact cross US 5 then follow Beech St. up to the big rotary just before the bridge to South Hadley. US 202 SB leaves the rotary then meanders its way via Lincoln St. to its concurrency with US 5 along Northampton St.

10 and 51 (conveniently hidden by I-39 - or not)
10 and 45,
41 and 141,
41 and 45,
61 and 151,
18 and 61,
14 and 61,
now the following will make it interesting:
12, 14, 18 and 151 make a quad concurrency on the Madison Beltline - 12 and 18 go east, 18 and 151 go southwest, while 12 and 14 go northwest - for a short bit.
add the former US-16 (now WIS-16) and you got a looooong one from Tomah to the Dells with 12. and then 14 and 16 in La Crosse
but Wisconsin loses due to the previous posts :D
The quad currency once also included WI-13 before it was truncated back to the Dells.
Utah doesn't have a whole lot of US routes, so we have:
6/50 (west)
6/89
6/191
6/50/191 (unsigned - thanks a lot, I-70)
6/50 (east - unsigned, see above)
40/189
40/191
50/89
89/91
163/191 (unsigned, and only exists depending on which document you look at)
Wyoming, on the other hand, has to be the winner among western states and probably in the whole country if you look just at what percent of US route mileage is concurrent with something else. They have:
14/16/20
14/87 (with I-90)
14/16 (partly with I-90)
14A/310
16/20
18/20
18/20/85
18/85
20/26
20/26/87 (partly also with I-25)
26/89
26/89/189/191

26/287
26/87 (with I-25)

30/287 (partly also with I-80)
85/87 (with I-25)
89/191/287
189/191
Matter of fact, the only Wyoming US route with no concurrencies is US 212, which doesn't even connect to any other US routes in the state!
Going to try Indiana too, as the state is known for that one beltway with five US routes on it at one point (my new profile picture :-D).

The only US routes in Kentucky that don't have concurrencies are 25E, 25W and (I think) 79. (I'm not sure if there is short concurrency where 79 crosses 41 or not; seems like I remember that intersection was going to be rebuilt.)
US 60 has a concurrency with every US route it intersects where the other route does not terminate.
After further review, this is incorrect. I don't know how I could have forgotten US 127, which has been routed across the western connector for years.
Also, after the rerouting of US 60 on the Newtown Pike extension, it no longer has a concurrency with US 27 and US 68

Indiana might be a contender for a couple of reasons: It's a primarily PLSS-grid state, but there are still plenty of diagonal routes, some of which zigzag along east-west and north-south roads for long stretches rather than making a straight line from Point A to Point B (US 35 comes to mind). Also, as of late, INDOT has rerouted plenty of US highways around cities, creating more concurrencies than ever before. I'll crunch some numbers later.
I found out that Indiana has 20 US routes and 33 concurrencies, making it 1.65 per route. The total mileage of US Routes in Indiana is 2826 miles, and about 8.8% of that (250 miles or so) is part of a concurrency. To prevent double- and triple-counting for mileage, I defined 2-, 3-, 4-, and 5-way concurrencies differently. I realize that this might have skewed the number of concurrencies a bit based on definition, but what else am I supposed to do with the mess around Indianapolis?
The 2 longest concurrencies are US 41/150 (55.83 miles) and US 50/150 (37.67 miles), which leads me to question why US 150 even exists north/west of Shoals, but that's another topic. The average length of a concurrency is 7.52 miles, but throwing out the US 150 concurrencies would make it 4.6 miles.
Ok, well, there's Indiana. What do the numbers look like for Georgia, Arkansas, and Wyoming?
Yeah, the routing of highways onto 465 and 469 definitely increased the concurrency mileage, but the very long concurrency of 150 with 50 and 41 really jacks up the total. Every US highway in Indiana has at least one concurrency, with 224 and 136 each having a single concurrency of less than a mile.

US-219/US-250 Elkins -to- Huttonsville
Fun fact: US-60 no longer has any multiplexes with other US routes over its 172-mile trek across the state. At various times, it has multiplexed with US-52 (Huntington), US-21 (Charleston -to- Chimney Corner, years 1926-1947), US-19 (Gauley Bridge -to Chimney Corner, years 1947-1977), US-19 (Road Fork Junction -to- Clifftop), and also with US-219 (Lewisburg). Plus there was a perceived multiplex with US-35 northbound on Seventh Avenue in Charleston within the Iowa Street "Crazy Loop" for a very short time before the latter was relocated after the Silver Bridge collapse. (That perceived multiplex still exists with WV-25).

MS
US 84- (US 61, US 425 [ew] [US 98??], I-59)
US 98- (I-55, I-59, [US 84??])
Historically, yes. Currently, no. Per MDOT, 98 ends at 84 in Bude, and has for over 20 years (they never did tell me when this was initially changed).
Since this topic got resurrected, I'll mention that although Vermont is a small state with only a few US routes (2, 4, 5, 7, and 302), with one exception all US route junctions in Vermont are concurrencies...and that one exception is only because 302 ends at 2.

An attempt for Illinois:
US 6: US 34, US 52
US 12: US 20, US 41, US 45
US 14: None
US 20: US 51, [US 12], [US 41], [US 45]
US 24: US 45, US 136, US 150, US 52
US 30: US 34
US 34: [US 6], [US 30], US 67
US 36: None
US 40: US 45, US 51
US 41: [US 12], [US 20]
US 45: [US 12], [US 20], [US 40], US 52, US 150
US 50: US 51
US 51: [US 20], [US 40], [US 50], US 60, US 62
US 52: [US 6], [US 45]
US 54: None
US 60: [US 51], [US 62]
US 62: [US 51], [US 60]
US 67: [US 34], US 136
US 136: [US 67]
US 150: [US 24], [US 45]
Partial list of former concurrencies:
US 34 and US 66 in Chicagoland
US 40, US 50, and US 66 in the St. Louis area
US 36, US 54, and US 66 in Springfield, with the US 36- US 54 concurrency stretching west towards Pittsfield
US 45, US 52, and US 54 around Kankakee?
US 51 and 52 around Mendota (prior to US 51 being upgraded into the freeway that became I-39)
US 51 and US 460 around Ashley
I believe there was a 6-66 concurrency in Joliet.
