I was tracing out the route of US 6, and while I was doing so, I noticed that it runs concurrent with US 62 for a bit in Pennsylvania. I was kind of surprised by that. 6 is quite a bit off from 62. 56 off to be precise.
That got me wondering how much the maximum disparity is for two-digit US routes or even Interstates that travel in the same direction. (So no mixing even with odd numbers. The winner there would probably be US 1 and US 98 meeting in Florida.)
Does anyone know? Are there other junctions or concurrencies of two-digit routes that are off by more than 50?
Are we allowed to mix the route types (I.E.: One being an interstate and the other being a US route)? Because if so, then I-95 and US 1 intersect at least once.
If you can mix route types, US 101 and CA 1 run concurrently at the Golden Gate Bridge approaches and several other places. But I don't think that's what the OP had in mind.
This most certainly is not what the OP had in mind, but it's the first thing that came to mind, and I just can't resist: The junction of US 1 and FL 9336. :sombrero:

I've found several instances of intersecting Interstates with a difference of 20, but only a few with more than that.
Probably the greatest is 45 and 69, which will be surpassed by 37 and 69 when 69 is complete.
US 421 and US 31 run concurrently in Indiana
Ah, I just noticed the qualifier "two digit" in the OP. Never mind. Biggest you get in Indiana then would be US 36 and 52 for a difference of 16.
VA 90003 and VA 132Y.

Funny had that one in mind when I saw this thread. Even the FL 997 to FL 9336 just a block west is pretty damn big:

For interstates, there's I-74 and I-40 in North Carolina (difference of 34).

If we don't want to count that one, there's I-44 and I-70 in St. Louis (difference of 26). Could have had a difference of 40 or 46 if I-24 had made it into the St. Louis area.

And maybe passed again some year by I-69W and I-35.

Some higher ones based on the OP's criteria:
US 1 and US 41
US 2 and US 52
US 10 and US 52
US 12 and US 52
Historically there has been
US 6 and US 66
US 6 and US 70 (maybe?)
US 8 and US 52?
US 11 and US 61
Also in Virginia, VA 90005 has direct connections with US 1 and VA 7; VA 90004 has direct connections to VA 7
The OP did say
no mixing even and odd. So

don't qualify.
Given US 6's route across the country, I'd say it has the most possibilities. US 52 also has a number of possibilities given its diagonal routing. In fact, anyone ever been to Joliet?
Someone mentioned the former US 66. That would have been a difference of 60.
Lots of non-compliant entries I'm seeing in this thread -- US and state, odd and even, 2dus and 3dus. Reading comprehension is a marvelous thing.

Exactly in West Palm Beach. Tied with US 2 and (former) US 99 across the country in Everett, Washington.
We already know the answers for this thread: I-40 and I-74 near Winston-Salem for Interstates, and US 6 and US 62 in Warren, Pennsylvania (US 6 and US 70 in Los Angeles historically, if they ever met) for US routes. This thread should be closed now (Unless US 84 is extended from Pagosa Springs, Colorado to Crescent Junction, Utah :sombrero:).

Yeah, what I'm mostly looking for, when push comes to shove, are essentially grid violations. If you mix even and odd, for example, you'll find something fairly extreme in two of the "corners" of the country, and I didn't think that that was particularly fun. Still, though, a lot of interesting posts in this thread. I didn't think of North Carolina with the Interstates, for example.
US41 meets US79, but that still isn't as big a difference as US1 and US41.
US2 and US52 is probably the biggest difference other than US6 and US62. US6 used to meet US66 in Joliet (referring to Brandon's post earlier)
I don't think any even Interstate pairings will top the new interchange of I-70 and I-44 in St. Louis.
For odd interstates, we have I-65 and I-85 in Montgomery. I-29 will be meeting I-49 in Kansas City once the 49 extension is completed. I-69 and I-45 are meeting in Houston, and like others have said before, branches of 69 are slated to meet I-35 and I-37 farther south in Texas.
One that was once semi-proposed but didn't happen: I-24 and I-66 in Kentucky for a difference of 42.
Logtown Road (CR 90938) and GA 74 send their regards (https://www.google.com/maps/@32.9139183,-84.1431011,3a,16.1y,13.26h,85.34t/data=!3m6!1e1!3m4!1sOMv44y1CYYtX-IRxYdJV2A!2e0!7i13312!8i6656). :D
But US 6 has always had that certain je ne sais you about it...kind of wandered off to the west and got really lost.

There's a whole discussion in the past on these forums about whether US 70 in Los Angeles ever extended west to the Four-Level (some of the signage for it along the US 101 southbound pullthrough did exist ca. 1958) - that would be the only way it could have intersected the Harbor Freeway, which was US 6 during the 50s and early 60s.
US 20 and US 62 cross paths near Buffalo. US 62 also crosses US 6, which might be the biggest difference among US routes that doesn't involve a 3-digit.
US 68 veers due north in Ohio and crosses US 30.
Doesn't US 42 meet US 6 in Cleveland?
23 and 35 isn't particularly impressive, but it's the best odd one I can come up with in Ohio...
In the Northeast, there aren't really any huge ones. US 1 and US 13, I-80 and I-90. I-83 doesn't quite reach I-95. US 46 is way off the grid, but doesn't cross any even numbered US routes.

Pretty sure we established that the OP is looking for disparities within a single grid, not mixing state/US grids.

Yes. Single grid, not mixing even/odd. In the spirit of that, I
assume that we should exclude spurs, as they break the grid. US 202 and US 2 is a big disparity, but not really if you know that US 202 is the second spur of US 2.
