Also before I officially say that it's only in these 2 states...
Do any other states besides Indiana and Ohio posts these blue signs at exit and entrance ramps?

Indiana example (link above is Ohio's)

New Jersey and Indiana: 1xx must be related to xx (and the same for all 3-digit routes)

This is the case in Mississippi as well - all MS 1xx routes are old alignments of US xx.

I'm tired of people abusing WY I-180. They just don't understand the greatness of it.

Kansas does this, but it might just be a Wichita thing.  Not sure about the rest of the state.

Arkansas and Indiana: Allow duplicating state route numbers with no restrictions

Do you mean they have multiple state routes with the same number, or do you mean their state route numbers duplicate US- or I- route numbers?

Multiple state routes with the same number.

In Indiana it is more that IDOT has dropped roads in cities off their rolls, making roads non-congruent on each side of the city, or have neglected to either co-sign a connecting road or have dropped a highway (such as the upcoming IN-37 exit of the I-69 corridor south of Indy) leaving remaining segments on each side.

Does this mean that, in Indiana, the discontinuous sections are considered segments of the same route, or are they considered separate routes?

The mile markers on one segment pick up where the other left off, so I guess that means they are segments of the same route.

Also the inverted shields for Louisiana and Idaho is not totally correct. Idaho does have shields that flip from black with white to white with black.

Louisianaís arenít inverted. Itís 2 different shield designs and color choices. Originals were green state with white text. The newer ones are white state with black text. It isnít an inversion of the old one (white state with green text)

Aw geez, I thought you were responding to the part about blue transition signs between highways in Kansas.  And I was preparing to reply that the markers don't actually have mile numbers on them.  Then I realized you were talking about Indiana!

I found an Indiana example, adding onto what I had earlier. Think I prefer Indiana's over Ohio, since the latter tries to fit everything in a square, while Indiana has the full road name, and exit number. For example, on the I-275 and Loveland-Madeira Rd exit, it's abbreviated as "LVLDMDA".

I will say this about the alphanumeric county route thing, though...  California and Iowa have a statewide (except Lake County, CA) system for numbering (or at least lettering) them.  New Mexico and other isolated areas don't have that.

Michigan has a state-wide system.

Cool!  I wasn't aware of that before now.

New York and New Hampshire: Regularly have alternate routes that go through the alphabet, such as NY 17K and NH 11D

Not trueóthis is a distinct feature of the Oklahoma route numbering system as well (reaching all the way up to SH-74F on the most-suffixed route, with one-offs for mnemonic reasons for 77H, 77S, and 412P).

Does internally tabbed mean full length?

If that's the case, add Georgia and maybe Michigan to the list

Wow I had legit forgotten about those other examples!

I remember threads over the years complaining about California using that style but it seems like in comparison it rarely generated mentions for other states implementing that practice too.

Washington and Oregon: centered exit tabs.

I'm not aware of other states that center their exit tabs. WA uses full-width internal exit tabs*, whereas Oregon uses actual tabs mounted above the sign, but both centrally-mount the legend and, in the case of Oregon, the actual tab itself.

* exception being SW WA, which does things weirdly and likes to use actual tabs mounted on the right edge of a sign as is normal elsewhere.

Georgia also has centered full length attached exit tabs. Them and WA are the only states I know of that does this, so those 2 can be a pair for this thread.
In the past, Missouri also installed centered exit tabs, similar to Oregon's, but it's all on the sides now. There's still a couple examples left in Missouri though; here's one at I-270 and MO 340

No, Kentucky does this as well.

An entrant in this thread: Virginia and West Virginia -- use markers for their state secondary systems that are used as primary route markers in other states (the circle).

Not sure about the exact specs, but Missouri's secondary (lettered) route markers looks similar to WV's primary route markers; both are squares with a thick black border.

Yeah, that was the first thing that came to my mind as well.

The 1971 Los Angeles exit numbering experiment had centered tabs as well:
https://www.aaroads.com/forum/index.php?topic=3442.0 (thread I began on that topic in 2010)


Also in looking up Illinois's internal tabbed signs, some of them are centered:

This used to be common practice in Missouri in the button copy era, although they no longer do so.
