My bet is US 1 to SR 9336 in Florida City, FL. Anyone know of such a large difference from the sum of 9336 - 1?
Appears to be I-980 and CA 24 for California.
10243: US 29 with secondary 10272 (signed with white rectangles), at Lee Hwy/Nutley St. n Fairfax VA.
Indiana doesn't have 4-digit highways so it won't get close to the largest nationally, but the largest in the state is IN 931 at IN 4 in Lakeville.

That takes the cake if you factor in those little white rectangles for sure.
But what about "fractional" highways in WV or hyphenated highways in LA?

I realized we could beat that one provided that "secret" route numbers count. The eastbound Dulles Access Road has a direct exit to Route 7. The Dulles Access Road's unposted route number is 90004, giving a difference of 90004 — 7 = 89,997.

Good point. I forgot US-1 runs concurrently with I-395 there. You'd think I'd remember that because I've driven over the bridge so many times, but I probably don't even notice most of the signs most of the time because the road is so familiar.
The largest one for Utah is probably 309 - at the junction of SR 9 and SR 318 west of Hurricane.
Michigan is clearly I-696 at M-1. The highest number in the state and the lowest number.
For Arizona it would be I-10 and AZ 587.

That "route number" and similar 90xxx numbers are assigned by VDOT for roads it doesn't control, but are owned and maintained by Federal agencies, for traffic and other statistics. I wouldn't consider them "route numbers" at all. This is unlike the other 5-digit routes in Virginia mentioned upthread, for VDOT-maintained secondary roads, which usually have some route number signage.
They are more like Alaska's unsigned 6-digit internal inventory numbers, which I also would not count. However, all the really low (western Alaska) and the really high (southeastern Alaska) inventory numbers are for roads isolated from the main highway network, and which have no intersections with the main network. The largest difference I could find within the main network is 150990 (Wiseman Road, off the Dalton Highway/AK 11 near Coldfoot) and 273010 (Wiseman/Nolan Road, branch from Wiseman Road), for a diff of 122020.

Given that Kentucky has regular state routes signed well into the 3000s, and with some 6000-series frontage routes in western Kentucky signed, I'm not sure I would attempt to find our example.
Here's KY 69 intersecting KY 6122.

Depends if you are trying to divide with the fraction or not.
With Nevada I believe the largest is NV 88 and NV 756.
Minnesota's is US 10 and I-694. 694 used to have an interchange with MN 5, but the latter route was truncated back past that interchange.
I think Montana's is Secondary 573 at MT 16 in Medicine Lake (NE corner of the state)
For Colorado, it looks like 462. CO8 & CO470 in/near Morrison.
Chris
NJ is 439 and 1
And what about Texas, what with all its four-digit FM roads?
Highest in Oklahoma would be the concurrency between US-412 and SH-3, difference of 409.
With just state highways would have to be 351 (Muskogee Turnpike) and 16, difference of 335.
I-990 is a good candidate for this, but unfortunately the lowest route number it crosses is 263. So that's a difference of 727.
NY 5/NY 635 in Syracuse gets 630, while NY 31/NY 531 is an even 500.

New York 890/New York 5 in Glenville. If we count signed New York 990V, it ends at New York 30 and beats that.
I believe Maryland's is 894 - between I-895 and US 1.
In North Carolina, NC-903 wiggles around in a weird multiplex with US-158 to create an intersection with the infamous NC-4 at Littleton. It keeps on zig-zagging north of Lake Gaston to match up with secondary SR-903 on the Virginia side.
A close second might be NC-906 at its ending at US-17 Bolivia Bypass. This is a fairly new route connecting to the Swains Cut/Middleton Bridge (a second crossing onto Oak Island, which was constructed in 2010). Also, NC-904 got extended to US-17 and Seaside Beach back in the late 1950s.
In Louisiana, it should be in Larose, La: LA 3235 & LA 1.
In TN it would be technically SR 1 and I-840. However, SR 1 is posted only on the mile marker signs as it is US 41 & US 70S at the junction with I 840.

Connecticut appears to be CT 2 and SR 910 (unsigned) for 908.
Signed: US 5 and I-691 for 686.
Iowa's is 409 for both signed highways, as IA 415 and US 6 meet in Des Moines. However, the unsigned IA 965 also meets US 6 in Coralville, and that difference is 959.

Off-topic, but NC-903 might be one of the weirdest state highway routes in the country
In PA - US 11 and PA 997.
in DE - DE 4 and DE 896.
Louisiana's got 3278
LA 1 at LA 3279 south of Cloutierville.
iPhone
For Vermont:
Signed: US 7 and VT 346
Unsigned: VT 11/30 and VT 9900 (Tollgate Rd./Winhall State Highway)
Using NC's secondary routes would basically be cheating since that's such a cheap way to get a big difference, numbers can repeat, and there's so many of them it would be tough to find the biggest difference. Someone already did NC though, so, for SC it's probably 908: JCT of SC 917 and SC 9 BUS.

My guess is that the record will happen in a Salt Lake City suburb where street numbers are roughly the distance to the origin in meters.
They only miss by a couple of meters and do not intersect, but it's going to be tough to be US-101 and Infinite Loop.
Elsewhere, it was correctly pointed out that the record for California appears to be 980-24. My hunch is that the record for interstates in California will be a tie between 805-5 and 880-80. I-980 and I-80 just miss. Florida and Washington state have potential for greater Interstate differences, but I don't think they are actually realized.
On the opposite end of the spectrum in California, US-50 and CASR-51 definitely have an interchange and I think CASR-1 and CASR-2 meet also. I think that I-10 and CASR-11 also intersect. Of course, in Sacramento, many numbered Streets intersect the same numbered Avenues (especially in the 40s).
For Alabama: 700, with I-759 at I-59. If AL 959 ever sees the light of day, that will overtake it.
The lowest posted difference would be 1, at I-20 at AL 21 in Oxford, AL 77 and US 78 in Ohatchee, AL 21 and AL 22 in Rockford, AL 17 and AL 18 in Vernon, US 80 and AL 81 in Tuskegee...and I'm quite sure there's a few others which are just one number apart.

I mean, those are street names and not route numbers. Not sure where you're getting the distance in meters thing...as an example, 1300 South is about 3.08 km (3080 m) south of the grid axis on South Temple.
But at any rate, if you want to count those you're not going to get any differences bigger than 14000 or so in the Salt Lake area. Your best bet is going to be in a rural county far from wherever the origin point is. The western part of Duchesne County in particular is a great place to look for this type of thing: among others, they have an intersection between 47000 West and 6000 South (https://www.google.com/maps/@40.2129733,-110.8791656,16.18z) for a difference of 41000.

How about I-41 and US 41 in Wisconsin? :sombrero:
The first junction that came to mind when I first saw this thread was that of A-2 and LP-9221 near Lleida, Spain. At the opposite end there has been junctions between same-numbered routes ever since the first route numbers appeared in 1939, e.g. N-240 and C-240 (now C-14) in Montblanc. A current example is the N-629/CL-629 concurrency in northern Province of Burgos.
Wisconsin's record is WI-24 and I-894.
Looking at our small difference variant on the topic, Virginia also is home to a 0:

If we're doing small differences now, then Utah's winner would be 1, which occurs in a bunch of places thanks to number clusters. I think I got them all below

Although it shouldn't be signed since the KY 9000 series are for internal use only, the Mountain Parkway at I-64 interchange does feature KY 9000 signs. So, the difference would be: 8,936.

Ohio's is OH 872 and OH 7.
872 is Ohio's largest state route number, with 852 being the next largest, so this difference of 865 is the biggest possible for state routes here.
OH 872 is less than a mile long, connecting OH 7 to the bridge over the Ohio River to Moundsville, WV.

And what about Texas, what with all its four-digit FM roads?
Texas' winner is a difference of 3729.
In the town of Mount Pleasant, FM-4000 has an interchange with US-271 and an intersection with US-271-Business.
For Wisconsin, you can also find the greatest alphabetical difference in a lettered junction. I think it's the junction between County A and County ZZ in Richland County, northwest of Richland Center.

Wisconsin has at least one 3-digit lettered route that I've seen (Trempealeau CTH-OOO near Osseo), so CTH-O and CTH-OOO would beat that.

It depends on whether you go strictly in alphabetical order, or put double letters after single letters and triple letters after double letters. If we're going by the latter, then I think the junction of D and VVV in Fond du Lac is the greatest difference.
D — VVV = CDLXXXV :hmmm:
^^ VVV is an improper use of Roman numerals.

FTFY.
Illinois is interesting in that its lowest-numbered state highway intersects its highest-numbered (signed) state highway: IL-1 and IL-394. But the difference between I-74 and I-474 is greater.
I-474 crosses IL-8, but there is no intersection. It's just an overpass.
So the answer in Illinois is I-474 and US24, at a difference of 450.
(I assumed here that only signed routes count.)

Hmm, tricky one. Technically, some FAS routes
are signed. Just not with shields, so you just have to know where to look!

My opinion would be to treat multiple letters as an overflow of the single letters, in much the same way that a two-digit number is an overflow of single-digit numbers. So let A = 1, B = 2, C = 3 ... Y = 25, Z = 26, AA = 27, AB = 28, AC = 29, and so on. I don't know if Wis does multiple letters that aren't doubles, but Missouri does.

Yes they do allow non-doubles, but 3-digit must be triples.
Sorry for the bump. Missed this thread previously.

With Nevada I believe the largest is NV 88 and NV 756.
The largest difference for Nevada is actually SR 893 & US 6/US 50 (diff=887), which is just east of the Major's Place junction in eastern Nevada. After that, it's probably SR 822 & US 50 in Dayton (diff=772), then SR 795 & US 95 north of Winnemucca (diff=700).
In the opposite direction tangent of the thread, Nevada probably has a few locations with a single digit difference. The few I could think of off the top of my head is SR 159 & SR 160 between Las Vegas & Pahrump, SR 206 & SR 207 west of Minden/Gardnerville, SR 304 & SR 305 in Battle Mountain, and SR 341 & SR 342 near Virginia City. We also have a "0", if you consider I-215 transitioning to CC-215 as a junction.
Ohio's largest has been mentioned already: OH 872 and OH 7
The largest between 2 interstates is probably I-85 and I-985, at a difference of 900. Ther other 9xx interstates don't intersect their parent (980 connects 580 and 880, and access to 90 from 990 is via 290).
For smallest difference, Ohio doesn't duplicate state routes and US/Interstates, so unless you're counting variants of the same numbered route separately, like OH 4 and OH 4 Bypass, the smallest difference is 1. Considering Ohio clusters state routes, there are way too many to list for the whole state. But here are some differences of 1 in the Cincinnati Metro Area:
I-74 and I-75
KY 8 and KY 9
KY 16 and KY 17
OH 122 and OH 123
OH 126 and US 127
US 127, OH 128 and OH 129
OH 561 and OH 562
Some examples of a difference of 0 from Indiana and Illinois I can think of, since both of those states don't have a no duplication rule
I-64 and IN 64
I-255 and IL 255

NJ is 439 and 1
440 intersects 1 Truck
Include unsigned designations and NJ 700's interchange with US 40 is larger.
If sticking with numbered junctions, I-676 and U.S. 30 meet just east of the Ben Franklin Bridge.
We're talking about exit numbers, so Kentucky's winner is most likely I-71/I-75 at I-275. Exit 185 + Exit 84.

Did you mean to post here (https://www.aaroads.com/forum/index.php?topic=23045.msg2557048)?
Yeah. Got my threads confused.
For Oregon, the largest difference would be where US-30 (and I-84) intersect with US-730, for a difference of 700. If US-30 doesn't count because it's duplexed with I-84, then the next highest difference would be just up the road, where US-730 intersects with OR-37 (a difference of 693).
For the lowest difference, there are a few instances where the smallest difference is 1. These are a bit easier to find after the Oregon Transportation started numbering state routes off of their hidden highway numbers in 2002-04, which were assigned by county in clusters of 10. For example, OR-334 and OR-335 intersect (and even run concurrent) north of Pendleton. For pre-2002 routings, OR-206 and OR-207 intersect and run concurrent between Ruggs and Heppner, OR-213 and OR-214 are concurrent for a block in Silverton, and OR-27's northern terminus is at US-26 in Prineville. Historically, OR-223 and the first iteration of OR-224 used to intersect near Lewisville.

And I was going to go with the ORH's for the smallest difference, with ORH 1 and 2 at the I-5/84/US 30 interchange.
You did miss 212 and 213 on I-205, and 212/213's former concurrency, though.
