Title: Highest exit suffix that isn't in Kansas City
Post by: Scott5114 on June 25, 2011, 04:55:23 PM
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?

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
