Futhest down the alphabet exit letter in your state

[peterj920]

Exit 1H, which is Saint Paul Ave off of I-794 is the exit with the letter furthest down the alphabet for an exit letter in Wisconsin at H.  What exit in your state is furthest down the alphabet?

I believe Massachusetts used to have an Exit 22W on MA 128, but not anymore. New Hampshire still has a few exits with W in them.

The New Jersey Turnpike has an Exit 15X.

[MikeTheActuary]

Connecticut still has a few W's as well.

[briantroutman]

Perhaps the OP could clarify, but I doubt he intended cardinal directions or the odd X as in the NJTP.

The OP can correct me if I'm wrong, but I believe the intent of this thread is to identify the last letter used in a continuous sequence for an exit number, and not the "N, S, E, W" designations that states used to use in lieu of the current "A" and "B".

Based on this criteria, Massachusetts only goes up to "C".  However, it occurs in seven locations:

Downtown Boston - I-90/MassPike east to I-93 south - Exit 24C
Woburn - I-93 to Commerce Way - Exit 37C
Marlborough - I-495 at Simarano Drive - Exit 23C
Chelmsford - I-495 at Lowell Connector - Exit 35C
Chelmsford - US 3 north to I-495 South - Exit 30C
Bourne - US 6 to MA 6A - Exit 1C
Lowell - Lowell Connector inbound at Gorham Street - Exit 5C

Once the new Kendrick Street/Highland Avenue interchange is opened, there will be an eighth location as well:

Newton - I-95 (MA 128) to Highland Avenue west - Exit 19C

h/t to spooky for reminding me about the Gorham Street exit on the Lowell Connector

[jbnati27]

Looks like our winner in Ohio may be Exit 1G off I-75 in Cincinnati. I didn't spend a lot of time on it, so anyone can feel free to correct me.

[hubcity]

New Jersey has an H, but on the Atlantic City Expressway's Brigantine Connector, there are no exit numbers...just exits A through H.

[Rothman]

Missouri: 2Y, I believe.

(Not my state, though)

[PHLBOS]

Once the new Kendrick Street/Highland Avenue interchange is opened, there will be a seventh location as well:

Newton - I-95 (MA 128) to Highland Avenue west - Exit 19C

Nope.  The Kendrick St. exit is now signed as Exit 19; though the signs/tabs were sized for a possible 19A.  The Highland Ave. exits (19A-B) are unchanged.  Saner minds prevailed on this one IMHO.
Regarding the above-post...

Never Mind.

In Philly, the highest letter suffix used is C for Exit 346C off I-76 (28th St. eastbound/Vare Ave. westbound).

[WillWeaverRVA]

Virginia has some W's on I-581.

[briantroutman]

Missouri: 2Y, I believe.

Anyone have an idea why the loop formed by I-35, I-70, and I-670 around the center of Kansas City has exits numbered from 2A, 2B, etc. in the extreme northwest corner running clockwise through 2Y?

On the surface, it looks like MODOT was fudging the fact that all three routes are roughly 1-2 miles from the KS border where they overlap, and this allows I-35 and I-70 to continue with "Exit 3"  after they split. But it is rather counterintuitive that I-35 jumps from Exit 1C to Exit 2U and I-670 from 1B to 2T. The advantage is that this avoids exit number duplication between the various routes in the downtown core.

But regardless, this would have to be the winner of the thread by any criteria.

AFAIK, the current northbound Kendrick Street number is temporary.  In the final configuration of Kendrick Street and Highland Avenue, per the Project #603711 construction plans, the exits will be signed as '19A', '19B', and '19C'.  As all three southbound exits will be accessed off a collector-distributor road, the southbound advance signing will read "EXITS 19C-B-A".

[Brandon]

51I in Illinois, for Congress Parkway off I-90/94 (I-94's mileposting).

[spooky]

I assumed that the Kendrick Street exit was numbered 19 as a temporary measure so that the existing signs did not need to be updated for the Highland Avenue exits. I also assume that new signage will accompany the final configuration of the Highland Avenue ramps, at which time the "A" will be added for Kendrick Street and the 19A, 19B, 19C sequence will be finalized.

Roadman also missed a C exit: Lowell Connector at Gorham Street - 5C

[pianocello]

I believe Iowa only goes to C, and I had trouble finding one that went even that high. I-35 has an exit 72C going northbound in West Des Moines, though.

[Eth]

Georgia has a pair of D's: 248D and 249D on I-75/85 in downtown Atlanta.

[Pink Jazz]

In Chandler, Arizona, the HOV ramp from Loop 101 Southbound to Loop 202 Eastbound is Exit 61D:

https://www.google.com/maps/@33.2990252,-111.8943536,3a,75y,157.9h,91.4t/data=!3m6!1e1!3m4!1slW7Xoorjq5BEQezmv1KgjQ!2e0!7i13312!8i6656

(Exit 61A is just before this interchange, the Price Road exit).

[1995hoo]

If we don't count directional letters, the highest I know of in Virginia is a "D" on southbound I-395 at the Springfield Interchange (Exit 1D).

(Yes, I saw Mapmikey's comment up the thread about the "W" ones on I-81.)

[vdeane]

In New York, excluding directional suffixes, it is 1D on I-95.

Next lowest is a tie between 1C and 4C (I-890, which remarkably survives despite the elimination of EB 4B and renumbering of 4A to 4; as such, I'm not sure whether I-890 counts as a true mile-based exit numbering system any more).

[jp the roadgeek]

Connecticut still has a few W's as well.

Directional suffixes almost always disappear when a state goes mileage based (exception being the NJTP; I refer to the Meadowlands/MetLife Stadium as 16W). I could see Exits 62 A-D being used for current Exits 49-52 on I-84 in Hartford.  Also could see it on I-91 in New Haven if Exit 0 isn't used for CT 34 and/or I-95 (assuming current Exits 4 and 5, which are partial interchanges for the same road, become the same number).

[dgolub]

In New York, excluding directional suffixes, it is 1D on I-95.

How about 9P on the Grand Central Parkway?

[GCrites]

The Cincinnati 1G mentioned used to go to at least 1J before the Fort Washington Way cluster was reconstructed. The WKRP theme shows it.

[freebrickproductions]

For Alabama, probably either C or D. Can't think of anything higher than those two, and the highest one that comes to mind is C (Exit 19C on I-565).

[Thing 342]

If we don't count directional letters, the highest I know of in Virginia is a "D" on southbound I-395 at the Springfield Interchange (Exit 1D).

(Yes, I saw Mapmikey's comment up the thread about the "W" ones on I-81.)

There's also 43D along I-295.

[jeffandnicole]

If we're only going down the alphabet on numbered exits and not skipping letters, there's exit 1D on I-76 in NJ.
