The NYSDOT frequently has the letter "W" as part of an exit number to
denote an exit for a westbound road. New York's not too big on the A/B
thing.

There must be three-dozen exits in a two or three-mile stretch on I-35 and/or I-70 in Kansas
City. I know of an Exit 2T and a 2U in one direction at least. I'll be up in the area later this
week and can confirm this, is anyone wishes.

I'm sure this will get lots of response. Good. :)

I know many 2&3di's have and Exit 0 (which ones, and do we want to
start a list?), but while driving from Cedar Rapids, IA, to Iowa City,
there is an Exit 0A and Exit 0B where EB (traveling south) I-380 meets
I-80. I thought that was one of the coolest things.

OTOH, where EB I-820 leaves EB I-20 just southwest of Fort Worth, TX,
there is an Exit 1A (before milepost 1), then Exit 1, but there is no
Exit 1B on either EB or WB I-820. Methinks the Texas DOT couldn't
fathom an Exit 0, although there is a milepost 0 where WB I-820
rejoins I-20.

And that reminds me to ask: What is the highest letter you've seen as
part of an exit number? I've seen an Exit 1R (I think; it's been a
while) in Milwaukee (I don't know which road); but I don't know if
there exist Exit 1A-1Q.

There is an exit 0 on I-70 in Wheeling, W. Va for westbound traffic to go to
US 40 and 250 on the island.
As for the letter. On the *old* Ohio maps (before they went computerized
two years ago) I believe there was a 1A-H for I-75 in Cincy.

OTOH, I find it annoying to see exit xxxA if there is no B+ to go along with
it.
I-71 NB, just north of the I-70 split, does that (the exit in question is
the US 40/Broad St. diamond, exit 108A)

There is an "EXIT 2T" and "EXIT 2U" on I-35/I-70 in Kansas City,
according to the 1998 AAA North American atlas.

Interstate 10 in Texas uses Exit 0 on the New Mexico border. By the way,
back in the 80's police from both states would sit on the border and catch
speeders coming into their state. I don't know if they still do that, but
beware.

There is an exit off the westbound Grand Central Parkway in Queens for
Flushing Meadow Park that is numbered 9P. I could have sowrn that it
wasn't there until a few months ago.

IIRC (which I may not), I think there's an Exit 0 where I-474/IL6 split off
from I-74 west of Peoria.

Does this imply that Exits 2A through 2S also exist?? That would be 21 exits
within one mile, which means an exit (on average) every 250 feet or so. That
may not be impossible, but it seems damned near so. IIRC, the usual rule of
thumb for city blocks is 20 to a mile, so this would mean there would have to
be an exit ramp *every single block*. I've never been to Kansas City, so I
don't know, but I'd like to know what the story is.

They are in Monroe County. Several exits have A/B that would elsewhere have
E/W or N/S: I-490 has it on Exit 7, Exit 9 and formerly on Exit 25. I-390 has
it on Exit 12, Exit 16, Exit 18, Exit 20 and Exit 24 (on NY 390).

Also the Thruway uses A and B, but for newer exits rather than directional
ones. --

Actually, the "0" is not used. It is simply exit A and exit B.

Further to the south, there is an exit 0A and 0B where southbound I-155
traffic meets I-55 in Lincoln.

It also can mean that one side of the highway has an exit , while the other
does not, or the original exit branches off to numerous exits. Possibly used
in an express/local format

Not quite, but darn close on the Sixth Street Expressway (north and oldest)
leg of the downtown freeway loop.

The reason for numbering the entire freeway loop around downtown Kansas
City -- which describes a rectangle of ~1 mi N-S x ~1.75 mi E-W (KC city
blocks are about 8 to the mile N-S and 16 E-W; this order is reversed where
the longer blockfaces are E-W, mainly in the S part of the city) -- as
permutations of Exit 2 has to do with the (original) two Interstates routed
around it.

No matter how one might have tried to slice it, one leg of the loop would
have not borne an Interstate designation and another would have been
multiplexed if I-35 and I-70 were signed on only two legs of the loop, as
35 enters the loop at its SW corner and exits at its NE, while 70 enters at
its SE corner and exits at its NW. Continuing I-29 onto the E leg of the
loop would have technically "solved" that problem, but at the cost of
redundancy from the loop to the 29/35 split N of the city and some
confusing exit numbers for the two ramps on that one leg. The completion
of I-670 also "solves" that problem for the loop's S leg, but it does
nothing for the exit-number question.

Here's why: The downtown lies just less than one mile E of the
Missouri-Kansas line, and I-35 from the S/SW enters Missouri ~2 miles SSW
of the loop's SW corner. Assume, for the sake of argument, that we now
have a situation where the S leg of the loop is I-670, the E leg I-70, the
W leg I-35 and the N leg multiplexed 35/70. Which route's exit numbers
govern the ramps on the N leg? I-35 would already be in the 2s at the
loop's NW corner, while I-70 at that point would have Exit 1(A). It's
simpler all around to treat the entire loop as though it were on I-35 on
all legs for numbering purposes.

But I forget where Exit 2A is, or whether the letters increase clockwise
(my hunch) or counterclockwise around the loop. If Exit 2A is at the
loop's SW corner, then the "I-35" logic is consistent.

What I can't figure out involves the exit on I-43 for WI 23 in
Sheboygan, WI. This exit is a typical cloverleaf interchange with
auxiliary lanes separate from and parallel to I-43 for all
entering/exiting traffic. Before the exits were renumbered, this exit
was marked EXIT 52 A-B, with A for 23 East and B for 23 West. After
renumbering, though, this exit became just EXIT 126 with no directional
designation. However, on the services signs before the exit, they have
"126E" and "126W" on them (to specify which ramp to take). My question
is this: Why was the A-B changed in favor of nothing? Is it stipulated
somewhere that there should only be one exit number (126) and no other
designation if there is only one ramp that actually leaves the mainline
freeway?

At a somewhat similar interchange with University Avenue on the NE side
of Green Bay (two ramps splitting off from one which leaves the
mainline), I don't believe A-B designations were ever used either before
renumbering (EXIT 113) or after (EXIT 185).

This is done on I-380 because the interchange with I-80 (just west of Iowa
City) is the southern terminus of the route (the freeway continues south as US
218, though). I suppose the "official" end of I-380 is at the middle of the
bridge over I-80, although the only END I-380 sign appears just north of the
first off-ramp.

By the way, I-380 is a north/south route (and is signed as such. You mentioned
"EB (traveling south) I-380".

Of course, most people who hang out in this newsgroup very often would know
that US 218 (multiplexed with I-380 for 20 some miles to Cedar Rapids) is also
a north/south route, despite all applicable numbering rules. It runs
perpendicular to its parent US 18 (running both north and south of US 18) and,
in fact, multiplexes with US 18 for 10 miles or so around Charles City, IA.

At the beginning of I-85 in Montgomery, it doesn't say which exit you're at
when you meet with I-65 and Day(?) St. On I-565 near Decatur, the first exit is
Exit 1.

At I-10 and I-75, if you go on I-10 west, it is exit 42 B-A, while if you go

That I've seen a lot on I-95 in FL. Exit 91 is FL 100 and 6 miles north of
there, is Exit 91C. There is no A or B. Near St. Augustine, Exit 95 is FL 16,
and 6 miles north of there is Exit 95A. Does anyone in Florida know what is up
with that?

Now that you mention it, this brings something else to mind:

Does the order of the cities on interstate exit signs really matter?
For example, in the WI 23 example I mentioned earlier in this thread,
the signs list "Sheboygan, Kohler", in that order, in both NB and SB
directions. Down here in Illinois, though, when approaching I-57 from
I-74, the order of the cities as you travel WB is "Chicago, Memphis",
while they are "Memphis, Chicago" as you travel EB. Presumably, this is
done to correspond to whichever ramp you encounter first. So why isn't
it the same in the WI 23 example I mentioned? Or does this vary by
state?

And it's marked as "A" and "B" because that is where Illinois 6 and I-474
begin.

And, there's always Exit 0 on the Indiana Toll Road at the Illinois
border.

I don't go on the north side of the loop as often as I do the south side. That probably
explains why I don't seem to remember seeing a lot of the letters. I can recall seeing exits
2Q, 2R, 2S, 2T, 2U and maybe 2V and 2W. Heck, there might even be a 2Y.

I don't recall having seen letters lower than Q. Maybe N. Definitely not anything lower.

The logic makes sense to me, since probably nobody refers to any part of the loop by its
route numbers. I wouldn't know for sure which way I-70 and I-35 go if you asked me now,
but I could follow them as I drive.

On the I-35/70/670 loop in downtown Kansas City (review your geography, all
three routes cross the state line closeby), exit numbers are not repeated
among these routes and there is a multitude of exits in this area. On I-35
in this mess is an exit 1Y.

In article <19981215144748...@ng-cd1.aol.com>,

Since, Florida does their exit numbering sequentially, It could be a new
interchange and since there was no number between 91 and 92 obviously they
have 91C and it could be that one half of the interchange is 91A 91B hence
the 91C or who knows

The same is done here in PA for example in the early 1990's a new interchange
was added between exits 10 and 11 on I-79 So the Southpointe Interchange was
numbered 10A they did the same when around 1995 during a sign rehabilitation
on I-70 they gave two previously unnumbered exits a letter 19A Monessen and
26A Hunker on westbound on 70

The PA TPK tdid the same when the added the New Castle and Mid county
Interchanges 1A and 25A

I wonder if that is why Virginia returned to exit numbering by mileage
because of the new interchanges that were being added in Northern Va on I-95
and around Richmond..to many letters can get confusing

Anyway, the highest I've seen is a C. That is on I-565 in Huntsville, Alabama,
where there is US 231 and US 431 at exits 19 AB, and then downtown roads at
exit 19 C. The whole interchange is funky!

This is in Columbus OH.
What do you mean? Exit 108A serves Main Street, and Exit 108B is US
40/Broad Street.

The US 41/WI 172 interchange in the Green Bay suburb of Ashwaubenon, WI
(a major I-compatible urban freeway to freeway interchange) is simply
'EXIT 165' (no suffix) on US 41.

Just south of there, northbound US 41 at Main St/Ashland Av (WI 32/BR-US
41) in De Pere, WI is 'EXIT 163 A' for Main St and 'EXIT 163 B' for
Ashland Av.

OTOH, the westbound Madison, WI 'Beltline' (US 12/18) is 'EXIT 261 A-B'
for Park St (EB US 14/NB US 151). Eastbound US 14 goes south from the
Beltline as an I-compatible freeway, NB US 151 goes north as 'Park St'
(a Madison city street), and both are multiplexed with US 12 and US 18
on the beltline west of there. This ramp connects to Park St with a
two-way 'T' intersection. Eastbound on the beltline, there are two
seperate off-ramps here. (This interchange is a 3/4 complete standard 'cloverleaf'.)

Wait a minute...isn't it a standard practice to encounter exit x-A then x-B
in the direction of increasing mileposts and x-B then x-A in the direction of
decreasing mileposts? That way, a given direction of the intersecting route
corresponds to the same exit number no matter what way you're going on the
freeway.

That being said, there is an anomaly on I-694 on the north side of the Twin
Cities. The exit to MN-51 (Snelling Ave) is 42A both eastbound and
westbound. Westbound (decreasing mileposts), west of the MN-51 exit there is
an exit for U.S. 10 that doesn't exist eastbound... and it's 42B. I need to
fix my exit page list to reflect (and comment on) this apparent error. (Adam
"Froggie" Froehlig is working with me to update and improve these pages with
more info and better graphics --- look for updates by New Years).

Yah, you're right. But it's been a while, and we were trying to get
from Dyersville (i.e., "Field of Dreams" ball/corn field) to Des
Moines.

BTW, I think it is *so* cool that IA puts weather radio receivers at

I've hashed this out before, but since you're interested...

Cincinnati has an Exit 1K. All the 1A-1K exits exist on either I-75
or I-71 (except, for obvious reasons, 1I ;-), and are not duplicated
between them. Since Exit 0 is not used, these have to cover two
miles of two Interstates, hence the large number of Exits 1.

They are not in strict order. Northbound:

1A I-71/I-75 split
Oddly enough this is signed as an exit off I-75 to I-71, not
vice
versa (probably because 71 is on the right and runs east from
there
to the Lytle Tunnels).
I-71 I-75
1B Pete Rose Way 1G US 50 West
1C Vine Street 1E Fifth Street
1D Covington, KY 1F Seventh Street
(Roebling Bridge) 1H Ezzard Charles Drive/
1J US 50 East MLK Blvd.
1K (off 1J) I-471 South

Southbound:
I-71 I-75
1K I-471 South 1G Freeman Ave/To US 50 West
1D Vine Street/Covington, KY 1F Seventh Street
1B Third Street 1E Fifth Street
1A I-75 North 1A I-71 North/US 50 East
(also signed for 1B-C-D-J-K)

Note that some of the exits are not present southbound. There is no
access from I-71 south to US 50 east (topography prohibits this --
Mount Adams is in the way ;-), Vine Street and the Roebling Bridge
exit are (were? see below) combined, and I don't recall 1H being
present southbound, though it may be.

I understand 1C and 1D (and maybe 1B as well?) have been permanently
closed as a result of the realignment of Fort Washington Way.

DejaNews is your *friend* (though you'd have to know an old ID of

From August 14, 1996, in response to something Sandy wrote about
I-670, a post I made after driving around the loop:

[Sandy:]

[My response in 1996:]
That one is 2U if you are going northbound on I-35, 2T if you
are going eastbound on I-670. (That's what my scribbled notes say...)
Exit *3* is at the northeast corner; however, at the
Paseo/I-35 split, the Paseo exit is denoted 4A and the I-35
continuation is denoted Exit 3 as well.
At the southwest corner and on the west side:

Clockwise from the northwest corner (I-35 south from I-70).

I've got enough junk cluttering this brain o'mine, you can't expect me to
actually clean it out and make room for new facts, now can you? ;-)

Of course, there may be a second reason for the persistence of this bit of
misinformation in my brain: the actual location of Exit 2A, which, if I'm
not mistaken, is closer to what would be MP 1 on I-70 in Missouri than MP 2
(which I think would be nearer the NE corner of the freeway loop, assuming
miles are measured using I-70's initial routing over the loop's E and N
legs). Similarly, the SW corner of the loop is (IIRC) beyond MP 2 on I-35,
but before MP 3.

And isn't Beardsley Road Exit 1 (EB only)? I'm not sure, but I think that
ramp comes after the off-ramp for I-35 SB (W leg of the loop) from I-70 EB.

If it's not (in which case it would be Exit 2B), then I-70 has no Exit 1 in
Missouri when it ought to have one.

You got me on your ultimate questions, but I was likewise under the
impression that, at interchanges with separate directional ramps, the first
city listed was the control city/nearest town for the first ramp and the
second one the one for the second ramp...

...and similarly, at a diamond interchange with a highway that runs on both
sides of the expressway, the first community listed was the first
town/control city to the left, and the second one was the one to the right.

Yes, it is, and it's standard practice in Florida, too; the example I
remember best from my childhood is the Dale Mabry Highway/US 92 exit on
I-275, which is 23A-B eastbound and 23B-A westbound. As opposed to the
other US 92 exit, Hillsborough Avenue, which is 30A-B northbound and 30
southbound.

My guess is that the US 90 exit mentioned above is mis-signed.

Yes... but there can be some interesting anomalies.

In Cincinnati, on I-71 northbound at the junctions of Ohio 562 and
Ridge Road with I-71, there is a sequence of exits as follows:

8A - Ridge Road East
7 - OH 562 West
8B - Ridge Road West

(I may have the directionality of the Ridge Road ramps backward...
it's been a while since I was there)

Exit 8A dumps you onto a local road with a signed route that takes
you
around a block to connect with Ridge Road; I'd suppose there wasn't
room for a proper directional interchange between the trumpet ramps
for 562 and Ridge Road itself, or a non-directional (diamond)
interchange for that matter.

Southbound, the exits are
8 - Ridge Road
7 - OH 562 West

In North Carolina, the standard seems to be that if it is AB in one
direction, it's BA in the other.

For truly odd, there's a point on I-40 in Winston Salem where there are
three exits in the space of one mile. "A" is in the middle: The order
of the three exits is xC, xA, xB (where 'x' is the milepost number).
This actually sort of makes sense. The A and B exits are for the same
road (one in each direction), and C is for another road. Presumably
they wanted to use A and B for the one road and directionally ordered it
(travelling east as milepost numbers increase, you read A first and then
B), and then C was given to the other exit. I think they couldn't fudge
and use 'x-1' instead of 'xC' because there was already an Exit x-1, and
maybe an Exit x-2 as well.

I'm not entirely certain, because it's been a long time since I've been
on that stretch of road (usually when I'm driving to Winston-Salem, I
turn away before I get to that point). But IIRC, what you describe is
not the case here.

Ohio doesn't attach letter suffixes when there are not multiple exits in
that direction within that mile marker numbers. This even happens when the
opposite direction has exits with letter suffixes.

The same holds true for I-75 Exit 74 (OH 41) in Troy, Ohio; NB it's just


plain Exit 74, while SB it's Exits 74B-A (remember exit #'s decrease as
you go SB) for for Covington and Troy, respectively. This is not

The same is true for Utah. I-15 exit 320 is for U-68 in Bountiful.
Southbound, there is only one ramp, labelled "EXIT 320", but northbound, there
are two ramps and they are "EXIT 320A" and "EXIT 320B". Until last week, when
the reconstruction project reconfigured the ramps, the same same thing was true
at exit 302, the junction with I-215.

There is one which is backwards, like the Ohio example, on I-215 at U-201. The
interchange is a cloverleaf. Northbound U-201 EAST is EXIT 20A and U-201 WEST
is EXIT 20B, while southbound U-201 WEST is EXIT 20A and U-201 EAST is EXIT
20B. The southbound exits are backwards, and should be 20B and then 20A, so
that the same exit number leads to the same direction of travel.

I show these accurately in my exit lists.

This will be taken care of when they convert to the metric system.
Three miles will become five kilometers. Each of the five exits can
have its own number.
