Looking through an atlas recently, along with the nicely done AARoads focus page on Texas, :clap: I noticed that Texas has two (that I saw) Exit 0's. The first is on I-10 at the New Mexico state line for FM 1905 serving Anthony. The other appears to be along I-40 at the New Mexico state line as well.
How many instances are there of an Exit 0? Is this just a Texas thing?
I saw it at the end of I-172 in Illinois. This is a little different in that it's the last exit on a route, not the first after it crosses a state line.
There's one on I-70 on Wheeling Island in West Virginia.
Illinois/Indiana along I-90. This is the State Line Interchange/Exit 0 for the Indiana Toll Road ever since it opened in 1956. Yes, interchanges along the Toll Road started at 0 even when it used sequential numbering (1956-1980). It also is Exit 0 for the Chicago (nee Calumet) Skyway as those mileposts start at the state line and go west to the Ryan.

Yep, Indiana likes Exit 0. Along with the Indpls. Blvd. exit on I-90, exit 0 appears on I-65, I-69 (original), and I-469, the latter two not being at state lines.
Also, a typical Indy-area sign of the type used for a route joining 465 appears on I-865 WB saying that US 52 WB should follow 865 to Exit 0. There are no exits on 865 other than the termini, and neither terminus has exit numbers, so the reference to Exit 0 is strange but fun. If they did number the termini, 865 would have only Exits 0 and 5.

The southern end of Toll-66 in New Stanton has some Exit 0's.
Weird that Texas has Exit 0's because the TxDOT exit policy seems to be to go to the next higher mile marker. Unless the interchange is smack on the state line, in which I could understand it.
I-90 at the Montana/Idaho state line has an Exit 0 but that's the only one I know of in the Pacific Northwest.
Several that could legitimately be "Exit 0" aren't:
I-405 in Portland, left-hand exit to Harbor Drive and Naito Parkway, is Exit 1A. (In fact, Exits 1B and 1C come before Milepost 1, but Exit 1D is after MP 1)
I-5 in Vancouver - SR 14 and Main Street are both less than a half mile from the state line, but are Exits 1A and 1B respectively. Exits 1C and 1D are just before the milepost.
I-205, also in Vancouver - SR 14 is just over 1/2 mile from the stateline, but in keeping with the milepost concurrency between the two states on 205 it is exit 27 (with Airport Way, on the Oregon side, being Exit 24).
On I-84, the first eastbound exit is definitely well past the milepost, but westbound the ramps to Holladay Street (Rose Quarter/Convention Center) and Morrison Bridge/Oregon 99E could theoretically be Exit 0s...but that would be quite confusing (as one of the exits is located on the transition to I-5 north; the other to I-5 south.)
I-105 in Eugene could have an Exit 0, but it's a never-finished interchange.
The Golden Glades Interchange on Florida's Turnpike is not Exit 0, but it was 0X. Sign updates removed it at the Turnpike split near Miramar several years ago.
The "X" is for the extension even though realistically its the mainline. The numbering system starts at Homstead at US 1 and runs along the Homestead Extension then up the mainline to its terminus at I-75 in Wildwood.
The other exits along the Turnpike section between the extension and Golden Glades that also have an "X" after the number are Exit 2X and 4X. The former is for the Stadium and the latter is the Northbound Turnpike for the Southbound Homestead Extension.
Nevada does not use Exit 0 at all.
If they did, there would be two of them: I-215's southern terminus in Henderson & the Primm exit on I-15 (CA/NV state line).
NJ avoids it with I-295/I-195/NJ29...having the 195/NJ29 ramps be labeled exit 60 instead of exit 0.
Michigan avoids it by numbering the end as Exit 1 (I-96, I-696, M-10, M-39*) or leaving it unnumbered (I-196, I-275, I-375**, I-496, I-675, M-6, M-8**)
* - M-39 begins at I-75 but its mileposts begin at I-94, so Exit 1 should be Exit 2 or Exit 3
** - Neither I-375 nor M-8 have numbered exits
I think the 5/805 split in San Ysidro would qualify for Exit 0 as well since, IIRC, it happens before the first milepost.
I-184's junction with I-84 is I-184 exit 0
i'm pretty sure most highways start with exit 0
I'm pretty sure you're wrong.

The I-40 exit at Glenrio is Exit 0. It's almost fitting since there's almost nothing left there.

At the exit on the south end of I-27 in Lubbock, where it becomes just U.S. 87, it's Exit 1. Then from there north it's 1A, 1B and 1C. If there's an appropriate place to have an exit 0, that's it.

Well, I-265 in Indiana also has an Exit 0 also, but that Exit 0 on I-164 that is shown will not be part of I-69, so I-69 will lose exit 0. Current exit 0 on I-69 in Indianapolis will eventually be exit 184.
The Dora exit on I-40 at the Arkansas-Oklahoma state line is Exit 330 in Oklahoma and Exit 1 in Arkansas. :spin:
I-380 has Exits 0A and 0B at its junction with I-80 west of Iowa City, Iowa. US 218/IA 27 continue south from that point, so that may explain the Exit 0 in this instance.

Darn, that's right--it's going to become 169(?) from 164. I wonder if it will still have an Exit 0 or if they will number it backwards so 0 is at the end that connects to 69.
Good point - it could be I-169 or something similar, but it would be a very short route. I think I-69 itself will have its first exit around two or three miles in.
The very south end of the Garden State Parkway in Cape May, NJ is marked as an exit 0.
I-65 has an Exit 0 at I-10 in Mobile.
Back in the mid-80s, Arizona had an Exit 0 (km! :colorful: ) on I-19 going into Nogales on the US side, which has since been changed to Exit 1-A.
I wonder if the change to 1-A was to avoid confusion for motorists thinking that Exit 0 would automatically dump drivers into Mexico with no chance of staying in the US?

Yes, I was thinking about how I-69 would
still have an Exit 0 even after its extension, but I forgot that it's taking over almost all, but not all, of I-164.

I've seen it marked as such on many maps, but from my recollection driving it, and from what I can tell on GSV, it's not signed as such in the field.

No, per California exit numbering policy. The ranges for exit number are dependent on where they are on the mileage: Exit 1's range is milemarker 0-1.5, 2 is 1.5-2.5, 3 is 2.5-3.5, etc.
I suspect that Oregon and Washington use similar schemes, although in OR 217's case, the exit numbers extend past their milemarker range, made painfully evident when the half-mile marker/reassurance shields were erected (ie, Exit 6 is slightly beyond milemarker 7).

I seem to recall it ending at an at-grade intersection which was not numbered as an exit.
A thought about Exit 0 and how it could be justified to states that don't use it occurred to me this afternoon while on I-71. I realized that Exit 0 is (imo) the best way to signify that an exit is at the state line or the end of the route, while Ohio's mish-mash of uses of Exit 1 is very ambiguous, especially when it comes to the latter case.
- I-271: southbound, there is no choice but the default onto I-71 SB, which nonetheless is signed as Exit 1.
- I-670: westbound, there are exits 1B and 1A followed by the default onto I-70 WB, which doesn't get an exit number at all.
- OH 8: southbound, there are exits 1B and 1A followed by the Central Interchange where "doing nothing" puts you on I-77 SB, but there are also exits for I-76 EB and for I-77 NB/I-76 WB which don't get numbers.
- I-490: westbound, there is an exit 1 for I-71 SB at the 90/71/490 partial stack, with no number for the default onto I-90 WB.
Consistency would suggest that Exit 0 should be used for all 4 cases because the final exits are at or very close to mile 0 at the end of the routes. The OH 8 case begs for some kind of exit number because all the other exits on all the routes at the Central Interchange have exit numbers; only the ramps from OH 8 to 76 do not, and Exits 1, 2, 3, 4, 5 are all taken (some with suffixes) already to the north--so Exits 0A and 0B would seem appropriate, if it weren't for ODOT not liking Exit 0. As it is, there are exit numbers for defaults with no choice sometimes and not others. Using Exit 0 at terminal interchanges would make sense and signal that the route number is ending so even if you "do nothing" you will be on a different route. (I've experienced talking to more than one confused visitor to Akron who didn't realize for miles that they were no longer on Route 8 after crossing I-76 because they missed the "END 8" posted in (of all places) the overhead pull-through BGS for I-77 SB. If it were part of an Exit 0, maybe that would be more of a signal.
IMO terminal interchanges shouldn't have any exit numbers at all. This is how it's done in NY (with the exceptions of NY 390 at the parkway and I-781).

I-4 in Florida uses no exit numbers at both terminals except for FL 400 (the continuation of I-4 after it ends at the east terminus) and Downtown Jefferson Street ramp in Tampa (that uses I-275's numbering scheme).

Even if the road itself phyiscally continues, just not as a freeway? I'd agree about not giving terminal interchanges exit numbers so long as it's just a simple split for each direction. Anything more complicated deserves exit numbers.

I could live with that if Ohio would get consistent with it. The four different scenarios I listed above (two endings defaulting onto another freeway with no other choice, two where the route number ends at an interchange where you can exit onto another route or default onto yet another) are all handled differently. The way that Indiana handles the endings of I-69 and I-469 are ideal and like you mention--the road continues onto a non-freeway and the exits from the mainline are Exit 0 (A-B on 469) while the default onto the non-freeway is unnumbered but well-signed with pull-throughs. The end of Route 8 in Akron really bugs me because all of the other movements at that interchange are either thru movements on route numbers or posted with exit numbers (exits 23A-B on I-76 or exit 125 on I-77), but being the south end of Route 8, the exits from 8 SB did not get exit numbers when ODOT numbered exits on 8 a few years ago. Thus there is a default onto another freeway route number and two exits that don't get numbers either, and navigation there would be helped by exit numbers.

I can tell you for a fact that the new BGSes they put up at Exit 0 do, in fact, have an Exit 0 tab on them.

Well, at least in upstate NY, that doesn't happen on roads that have exit numbers... the closest is the Adirondack Northway, which has its own issues.

Is Exit 0 just the slip ramp to 109 North? Or does the BGS refer to the whole intersection as Exit 0?

They refer to the whole intersection as Exit 0, but they don't denote a difference (like A and B) for the directions you can go at the intersection.

One would think that for highways less than 10 miles (?) exit numbering should just be sequential rather than by milepost. Once the highway is longer than 10 miles (?) milepost numbering begins to make more sense.

But that's how you get fun stuff like suffixes going up to G! :P
Or X, like on the New Jersey Turnpike (of course, that's only because there's two rail lines that cross near there, not that there are 23 other exits between two original ones.

Why? It should be distance throughout, regardless of length.
With that said, I-84's first 10 miles are sequence based and not distance, to allow milepost synchronization with the mainline that begins at the northern I-205 interchange. (It needs a name -- the Maywood Park Junction; the southern one can be called the Gateway Interchange).

There is a 2Q for Truman Road. I, O, and Z are indeed the suffixes skipped.
Of course exit 2 is not really a "legitimate" exit number, since it is shared between I-35, I-70, I-670, and whatever else multiplexes through there.

Wow, half mile markers? How old are those? I don't recall seeing them last time I was on that wretched freeway, but it's been a while.
This may be material for another post, but on this note I remember seeing mile markers every tenth of a mile in southeastern Wisconsin (specifically the 94/41 multiplex between Milwaukee and Chicago) that seems a bit excessive...

Depends on the state. Ohio and Kentucky sure seem to like it. NJ signs tenth-miles all over but using really tiny signs you can't see until you're on top of them.
Oregon hasn't used the 1/10 markers. ODOT's just recently started using .5's on OR 217, and I don't even recall seeing them in Vancouver, WA on any of the freeways there. Definitely not 'Everywhere' like you asserted, silverback.

Have not seen them (or even .5's) anywhere in Washington.

Even relatively heavy users like Ohio and Indiana don't post them for too far outside of large cities. For example, the blue 2/10 mile markers don't go north of Lebanon on I-65 and stopped south of there until the first phase of the recent work between 865 and Lebanon finished. On the Indiana Toll Road, they have them from the Illinois line through South Bend but no further east. In Ohio, they taper off on I-71 in Medina County heading out of Cleveland and aren't seen again until near Columbus, except for a random couple of miles where they were left behind after the 3-lane widening (they were present during construction but not before, evidently to ease accident/incident reporting). I-77 leaving Cleveland has them south all the way through Canton but they taper off too. So not even every mile of Ohio or Indiana Interstate has the .2 mile markers--actually more mileage probably doesn't have them than does.
As far as Exit 0, I doubt that there will ever be national consistency on it when even within states now there is not total consistency with how to handle exits at termini and state lines. Ohio hasn't even decided how it wants to handle termini without using Exit 0, much less introducing it.
Virginia posted .1 mile markers on interstates (and I believe selected other routes).
Massachusetts posts .1 mile markers on EVERY state highway*, though I've noticed a few minor ones where the mile markers are noticeably absent
* - By "state highway" I mean the state's definition, so not a continuous route but rather roads maintained by the state - towns often maintain urban portions of state routes, and are thus responsible for all signage on those portions.
I-40 in western Tennessee has 1/10 mile markers sporadically. It may be something they're experimenting with or phasing in.
I have seen some states use the number 1 instead of 0. NC uses Exit 1 on I-95 on the interchange that lies right on the NC-SC Line (aka the South of The Border interchange named after the tourist trap there) and FL uses one on FL 429 with its southern terminus near Disney World it uses Exit 1 for one of the ramps to I-4 while the other is numberless. There is an Exit 1A used for an interchange approximately 1 mile north of the 0 mile marker that allows for the number to be spread out over the first mile.
I-75 used to have its southern terminus in Florida with Exits 1A & 1B. That may not count as that was in the days of sequential numbering in the Sunshine State, but nonetheless FDOT chose to use that rather than go use the 0.

This is Oklahoma practice; Exit 1 on I-235 goes up to exit 1G rather than use an Exit 0. If a 0 were used, we would see 0A, 0B, 0C, 0D, 1A, 1B, 1C.
I-69 will have its exit 0 moved further south in the next 2 months

Non-freeway routes in NJ are done by mile (standard mile marker signs) and half-mile (smaller ones). I don't know if the freeways have tenth-markers over their entire lengths -- rural areas of I-78 and I-80 might not have them (but I don't recall). The Turnpike, Parkway and AC Expressway have tenth-markers over their entire lengths.

It may not even have one at all depending on if an interchange gets built immediately adjacent to its Ohio crossing.
Louisiana typically uses blank exits instead of 0's. I know that 210, 310 and maybe 110 are blank at their termini with I-10. 220 is a funny one. One exit before 20 is 1A, the I-20 exits are 1B and 1C, and then after the change to LA 3132, the exit is 1D and then they ascend again.

Not 110. The termini exits are marked as 1I and 1J.

Not to mention that the order of exits is I/J, A, B, C...

So approaching the end of the route, exits go 1C, 1B, 1A, 1I-J. If ever there were a place for Exit 0.....
(And why would they have chosen 1I? If they used Exit 0, would they have suffixed it to be Exit 0O or something?)

Has it always been suffixed that way at I-10? And Purdue Bill, the number 1 exits go from 1A to 1H going northbound on 110, so I and J weren't just picked at random

But why use I that looks like a numeral, and why go out of order with the highest letters before A? It would have been better to either use zero or not number at all.
oh no, I totally agree with you. I think it needs zero or blank exit

The ramps for Interstate 10 were assigned exit numbers (1I, 1J) in 2003 during a sign replacement project. Before that, they were unnumbered.
Wisconsin uses exit 1 where applicable. Some routes (I-39, US 45 & 53) start a higher numbers due to where the highway enters/starts.
QuoteTopic: Exit 0. How often is there one?
Every other weekend.
There are two Exit 0's I can think of.
PA: PA Turnpike 66 at I-70/US 119
WV: I-70 at Wheeling Island
The southern-most exit on the Garden State Parkway in Lower Township, NJ is Exit 0.
Didn't see this mentioned here or on the newer thread. I-94's western terminus near Billings, MT has an exit 0 to eastbound I-90, while continuing straight leads to I-90 westbound: https://www.google.com/maps/@45.832636,-108.388216,3a,75y,215.58h,93.13t/data=!3m4!1e1!3m2!1sR1g6li-0sGPiCY8Fnla_7A!2e0 (https://www.google.com/maps/@45.832636,-108.388216,3a,75y,215.58h,93.13t/data=!3m4!1e1!3m2!1sR1g6li-0sGPiCY8Fnla_7A!2e0)
