I was noticing that in the interstate system that in NYC, you have 6-7-8 to make the route number 678. In Dallas, TX you have I-345 which is 3-4-5. Those are the only two 3 digit interstates like that but TexDOT fails to sign I-345 at all. So in essence I-678 is unique in this fashion like I-555 is the only three digit interstate to use one number out of two to be signed. The other being I-444 in Oklahoma not signed at all.
In US highways US 123 is totally unique as it's the only three with consecutive numbers in that situation.
Interesting.

US 321
I-890 qualifies - on a keyboard or calculator . . .
For decreasing consecutive numbers, I-876 and I-765 currently don't exist, but are somewhat possible for the future based on the non-interstate corridors nearby. I-987 and I-543, a bit less so.
Also US 789 :sombrero:.

Don't forget I-[0]12 in Louisiana.

Never heard of I-543.

None of the corridors he listed currently exist. He's speaking hypothetically.
Fictionally, anyway.

And I-210, found in Los Angeles and Lake Charles.

I wouldn't count that. As a 2di, there's really no implied 0 there. I would count it, though, if there were an I-1, since 1di's are in essence 2di's with an elided 0.
Any roads with 4 consecutive numbers?

There's a KY 2345 in the Cincy metro area, at NKU.

TM data has examples of roads numbered 1234, 2345, 3456, 4567, 5678, and 6789.
The first three digit I thought of was I-345, which is near me.
Texas has FM Roads 1234, 2345, and 3456.
A stretch but 5 consecutive numbers?
I recently finished clinching A-1234 here in Aragon, Spain, if that counts. There will be an A-2222 (four of the same number) nearby in a few years. In fact there will be A-2, A-22, A-222 and A-2222 all within Aragon, the first two are freeways, the other two regular roads.
