Highest exit suffix that isn't in Kansas City

[Scott5114]

What's the highest exit suffix in use that is NOT in Kansas City? The highest outside of Kansas City (which goes up to 2Y) is in Chicago, on I-94 (Exit 51I for Congress Pkwy/Chicago Loop). After that, there's a 1G from I-235 in Oklahoma City.

Does anyone know of a suffix higher than I that is the result of actual sequential suffixing and not a clever scheme like Kansas City's?

Well, New York State has quite a few N's, S's, and W's  

My guess is that Chicago's would win second place, which is certainly a LOT of exits in a 1 mile stretch!

I-794 goes up to 1F

The AC-Brigantine Connector goes up to H (no numerical prefix): http://www.alpsroads.net/roads/nj/bc/

Before I-43 got extended down to Beloit and still began at the Marquette interchange, its "Exit 1s" started at a high letter to avoid confusion, I guess, with I-794.  I remember going to the Schlitz Brewery as a kid and we got off at Exit 1U!

Of course, since I-43 exits have been renumbered for its new terminus, those exits are normal A, B, C, etc.

I-110 in Baton Rouge has Exits 1I and IJ for its southern terminus at I-10, which used to be unnumbered - before that, the highest suffix was Exit 1H for Laurel Street.

Does 15X off the New Jersey Turnpike count?

[roadfro]

Nevada doesn't go much past "A" or "B". There's only one "C" suffix that I know of...

No, X is for the Xchange (Secaucus Junction rail station), not because it's the next letter after W.

This is off-topic, but I just noticed, in that diagrammatic sign for Marina/Brigantine and Renaissance Pointe/Borgata, that the diagram was put into perspective, and thus the lanes appear wider at the bottom and narrower at the top.  I've never seen that done before.  That's a really cool, subtle nuance!

Exit 2Y in Kansas City? Where is it located in Kansas City?

http://en.wikipedia.org/wiki/Downtown_freeway_loop_%28Kansas_City%29 has a good explanation of the exit numbering scheme of downtown Kansas City.

There's an Exit 155P on the Garden State Parkway. I assume the "P" denotes something, but I don't know what.

The Fort Washington Way (I-71) reconstruction project in Cincinnati retired a lot of suffixed exit numbers, but it seems there's one left: 1J, southbound off / northbound on, for I-471.  I seem to remember there may have been a K in there years ago, but I don't have any detailed historic maps to reference.  As it is, the only reason I know 1J is still there is the Wikipedia exit list.

That exit leads to a little spur - numbered NJ 19 if memory serves - into Paterson.

Slightly off-topic, but I was on 81 in West Virginia today and was surprised to see that one of the exits (16 maybe) was broken down into E and W rather than A and B.  Thought that only happened in sequential-numbering states.

Yeah, I think it's WV 9 in Martinsburg that has 16E-W
