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.
Connecticut still has a few W's as well.
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
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.
New Jersey has an H, but on the Atlantic City Expressway's Brigantine Connector, there are no exit numbers...just exits A through H.
Missouri: 2Y, I believe.
(Not my state, though)

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...

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".
51I in Illinois, for Congress Parkway off I-90/94 (I-94's mileposting).
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
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.
Georgia has a pair of D's: 248D and 249D on I-75/85 in downtown Atlanta.
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).
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.)
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).
Quote from: MikeTheActuary on August 30, 2016, 02:49:32 PM
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).

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

There's also 43D along I-295.
If we're only going down the alphabet on numbered exits and not skipping letters, there's exit 1D on I-76 in NJ.
I-110 in Baton Rouge, LA, gets to exit 1H.
Florida has a couple C's and a D on I 95 near downtown Jacksonville.. 353D is the exit for Kings Rd(US 23)

Once the new ramps are built on I-20/59 and I-65 at Malfunction Junction in Birmingham, there will be C's and D's on I-65 SB and I-20/59 E/N. The new 6th Avenue exit from 20/59 will be 124A, 65 SB will switch from 124A to 124B, 65 NB will switch from 124B to 124C, and the new 17th Street exit will be 124D.
The new 17th Street exit from 65 SB will be 261A, 20/59 W/S will switch from 261A to 261B, 20/59 E/N will switch from 261B to 261C, and the new 6th Avenue exit will be 261D.
Washington has a D, but it maybe shouldn't. There's a 1D in Vancouver. Northbound however, it's combined with 1C. Southbound, 1B is missing. So in both directions, there are only three gores, but northbound it goes 1A > 1B > 1C-D, and southbound it goes 1D, 1C, 1A. (Though it makes sense, since that way the four cross streets have the same exit number in both directions.)
I think there are two other Cs in the state, coincidentally also by the starting terminus of the route: SR 16 in Tacoma, and I-90 in Seattle. The I-90 one definitely shouldn't exist though, since there's no A in either direction. (2B is for I-5 south, 2C is for I-5 north.) I think if they had built it as originally planned in the 50s (which would have connected it the 99 viaduct), 2A would have been for 4th Avenue at the current terminus.
Exit 1E off the Santa Ana Freeway/US 101 southbound in Los Angeles, Mission Road, is likely the highest lettered exit I can think of in California. (This also leads to a thread idea I'm about to start on a tangent about lettered exits... here: https://www.aaroads.com/forum/index.php?board=12.0 )

I'm sure quite a few western states don't. North Dakota only has one interchange where exits reach B, which would be the I-29/I-94 interchange. Montana, and Idaho also do not have states that don't reach C. South Dakota does with Exit 1C off of I-190, along with Wyoming in the I-80/I-25 interchange area where they both have a C exit.

Maybe
Wyoming Montana,
both Dakotas North Dakota, or even Vermont (Edit: peterj920 has pointed out both SD and WY have a C exit). Not Spain (although that is not a state but an entire country), as there are a few Cs around Madrid. Bonus points for that one, as exit numbers are km based and thus exits must be tightly spaced to get further down the alphabet before rolling up over to the next number.
France (sequential exit numbers) uses x.1, x.2, etc. if they insert an exit between two existing ones. I don't think they go further than x.2, though. Both the UK and Germany use letters, although I have to see a letter other than A. Italy directly doesn't have this issue... because they don't have exit numbers either.
PS: Wyoming even has a couple of D exits, but it appears they use letters according to direction (A=South, B=West, C=North, D=East), so I-80 only has the A and C exits while I-25 gets B and D.

Montana, and Idaho also do not have states that don't reach C. South Dakota does with Exit 1C off of I-190, along with Wyoming in the I-80/I-25 interchange area where they both have a C exit.
Wyoming kinda cheats though, with exits 359 A-C off I-80 for I-25 and exits 8B-D off I-25 for I-80. Having driven through there, you wonder if you missed an exit or two, but nope--the successive cloverleaf ramps skip a letter so indeed you didn't miss something.
I had already noted that based on observations from Street View. Without that cheating, Wyoming doesn't quite reach C. I was surprised about Idaho, I thought it would go to C around Boise.
New Mexico has one C & D, along I-40 at and by the I-25 interchange. Nothing else goes over B.
Nevada only goes up to "C", with only one true instance and one sort-of instance.
On I-515/US 95 in Las Vegas, the exit to I-15 is exits 76A & 76B (north & south, or south & north, depending on direction) while exit 76C is for Martin L. King Blvd.
On northbound US 95, there is an HOV-lane exit to Summerlin Pkwy labeled exit 81C. I don't really count this one, because exit 81A already goes to Summerlin Pkwy.
I-190 has an exit D in Chicago
It gets crushed by exit 51I along I-94 (and I-90, but that section uses exit numbers from I-94).
Nebraska goes to 2D on I-480 on the north side of downtown Omaha, for the 20th St. and Capitol Avenue exit. I-80, I-180 and US 34 in Lincoln have an exit 401D for eastbound I-80, but that is based off a directional system instead of a sequential system.
Maryland only has C or D and it could be in Baltimore or Frederick.
The highest letter I can find in Ontario is a C on the 416 (Exit 75C Holly Acres Rd/Richmond Rd).

Throws me for a loop every time I have to use that exit complex, so used to E meaning East.
On a related note, I wonder why the exits going westbound dont all have letters like on the eastbound side.
Currently, eastbound is:
21 for 108th St
22A for Grand Central / Northern State Eastboumd
22B for GCP Westbound
22C/D for the Van Wyck/678 Southbound and Northbound
22E for the service road/College Point Blvd (which maybe shouldnt be signed as an exit anyway since it uses the service road)
Westbound:
22B for College Point Blvd, use this for VWE/678
22A for GCP Westbound/Eastbound and 108th St, all with unnumbered ramps.
Why not have 22D,C,B,A or 22C,B,A,21?
I prefer directional suffixes as its quicker confirmation of which ramp comes first and which one you get off at. LI usually saves A,B,C suffices for supplemental exits, and even then sometimes piles on a direction (ie 28AS, 28AN). NYC is really inconsistent with their exit signage.
