Do any states have a Route 0? I know that AASHTO doesn't allow 0 to be used on either the Interstate or US Route networks, but every state generally maintains its own network of roads.
Frankly, though, I see no reason why there couldn't be an Interstate 0 or Route 0. It's a perfectly valid even number (could have 100, 200, 300, etc. as 3di) and would work very well as an even more southerly Interstate (south of 10) or the most northerly US Route (north of 2.) At least, it could have had the number been put to use when both systems were being planned.
There some route 0 roads in Europe, for example R0 as the ring road of Brussels and M0 as the Budapest beltway. I believe there is another A0 somewhere in Asia or the Caribbean, but I can't recall where.
The mathematical reason: The interstate numbers are a subset of the set of positive integers, and since 0 isn't a positive integer, it can't be used.
The actual reason: I don't know. It might be to "normalize" the grid system a little (there's one more north-south transcontinental possible than east-west). It might also be because most people (who aren't programmers) start counting at 1.

There's one in Sri Lanka.

Your mathematical reason fails, because while they are a subset of the positive integers, if we're arguing from a solely mathematical standpoint, they are also a subset of the non-negative integers, and for that matter, of all integers, rational numbers, etc. (I have a sudden urge to change my avatar to the shield for Interstate Pi.)
Essentially what the original poster is asking is
why the interstate numbers are thus far limited to the positive integers (also known as the
counting numbers) and I have a feeling it's the last reason you gave.
I use Interstate Pi for some of my maps, along with Interstate i, e, Delta and Sigma, to fill in the more diagonal routes outside the grid proper.
yes, but is there an e, pi, i, 1 multiplex? if so, is it with route 0?
There is now :twisted:
Oklahoma's planning maps show a few SH-0s, as well as a SH-0B in Langston. None of them are signed, however. More likely the "SH-00" label is just to show that the route is state maintained but not numbered or marked.

Zero is neither positive nor negative but it is an even number, and thus I don't see why AASHTO couldn't have had an east-west Route/Interstate 0, other than them just finding it to cause confusion or something.
I want a Route π, it would be delicious.

Well, if you define an "even number" to be any number divisible by two, it is an even number, but then again it is also an odd number, because 0 is divisible by anything. I guess.

that is not the definition of an odd number. odd numbers are those of the form 2N + 1, where N is an integer. 0 is not of that form.

Mincemeat can contain meat. I should know.
Not normally, any more, though.
Don't mean to hijack the thread, but I have a curious question about Wisconsin and Missouri's lettered routes. Do they ever cross the capital "I"s to prevent it from getting mixed up with a "1"? Do they even have a route I or route II?

Doesn't the "1" under both FHWA Series and Clearview have that little tail to distinguish it from a lowercase L or uppercase I?

Ilion, NY is signed with a crossed capital I to prevent it from reading |||on. On the other hand, I don't believe Illinois does that with their state name.
Missouri doesn't use G, I, Q, S, or X in their lettered routes, to prevent confusion with 6, 1, O, and 5 respectively. (No idea why they don't use X.)
Quote from: Scott5114 on November 03, 2010, 12:53:25 AM(No idea why they don't use X.)
looks too much like a digit "3".
seriously, I have no idea why. Is X used for planning purposes as a route whose number/letter designation has not yet been finalized?
I don't know for sure. In the article that I gleaned the information from, the author just made a lame joke about "nobody wants to drive on an X-rated highway". I'm sure if someone really wanted to know, you could email MoDOT and they'd answer. I know R is generally reserved for roads to recreation areas, but that too was outright stated in the article.

There is not a highway numbered "1" (in WI) so the letter I works fine as a county road marker and just for added fun:

From what I've seen, most of the "County I" signs in Wisconsin do actually put serifs on the letter. (Here's (https://www.aaroads.com/forum/index.php?topic=2090.0) a picture of one.) That said, a lot of county route markers are furnished by county sign shops and have fonts that are a little "off."
I'm aware of a few County IIs around the state...don't know of any III, though!

The US interstate and highway systems never considered zero (0) a real number to ever be used/commissioned. Note they start from 5 to 99 (from West to East) and 4 to 96 (from South to North), to leave out the first 3 numbers is an interest of mine I pondered. In the highway system: 1 to 101 (East coast to west) and 2 to 98 (North to south) the virtual opposite of the Interstate system. The state and country road system have their own rules, they can decide on what to name and number a road, but be cautious with the number #13 and the triple-K associated with a hate group.

Funny how the US system considered 0 & 1 to be the important numbers, yet the interstate uses 5 & 0 as the alpha numbers.
Sorta related, but the bus route along Broadway in Denver is Route 0. The reason for this is because of the address system in the Denver region. The center point is Broadway and Ellsworth, with the numbers increasing accordingly as you travel from that intersection.
Because Denver is a grid city, RTD tries to match bus route numbers to the roads address. So Route 6 would travel on the street that is 6 blocks from the center intersection, Route 40 on 4000, Route 120 on 12000, etc. (Does that make sense?) As such, because Broadway is 000, the bus route number is 0.

Winnebago County 'II' (road is formerly WI 110 and WI 150) is marked with signs like that.
Anyways, there is no confusion with that in Wisconsin as ALL county highways in the state are lettered.
Also, I like Wisconsin's standard county shield much, much, much more than the MUTCD pentagon.

Letter O is used. Q is not, used, however, because it could be confused with letter O. Apparently MoDOT doesn't consider letter O being confused with zero to be enough of an issue to warrant not using letter O in lettered routes. (There's plenty of single O routes too–I've clinched Greene County's.)
