Any others that are old school abbreviations like Ark instead of AR, or Mass instead of MA?

Ohio is sometimes abbreviated as "O.", though I don't have photos on hand.

Ohio is sometimes abbreviated as "O.", though I don't have photos on hand.

Such as "Columbus O." as used to be found in Indianapolis on the bgss.

Lots of "Penna" Turnpike signs still around.

This reminds me of one of my favorite comedy bits.  6+ minutes of comedy about state abbreviations.

Lots of "Penna" Turnpike signs still around.

There used to be an overhead LGS pull-through sign on the former I-95 near Trenton that used "Penna" as the control "city." I have no idea whether the sign is still there, nor whether they would have simply stuck an I-295 shield over the I-95 shield or whether they would have replaced the whole sign.

Wisconsin boat registration uses WS as the state abbreviation.

Wisconsin boat registration uses WS as the state abbreviation.

And Michigan uses MC.

As long as were're not mailing the boats, what does it matter?

Wikipedia has a useful list of U.S. state abbreviations that includes the Coast Guard's vessel number prefix abbreviations as well as the various traditional abbreviations.

Illinois (IDOT and ISTHA) commonly uses the older "ILL" and "Ill" on signage for state routes.
Examples would be like: "ILL Route 53" and "Ill Route 53".

I see KA for Kansas once in a blue moon.

So once in about 11.7 nanohertz according to Mr. Google?

I use "Cali" for California, which is not included in the Wikipedia list linked above.

I know that the approaches to the Fort Steuben Bridge in Steubenville were signed "Weirton, W.Va.," but it's been demolished and I can't find any other examples.

Years ago, I seem to recall some Indiana I-70 signage having a control city of "Columbus, O.H.," which isn't old school so much as just incorrect.

[US 89]

I-84 near Twin Falls, Idaho. Taken in 2010; looks like this sign disappeared during an interchange reconstruction sometime between 2012 and 2015. The second control city is now Sun Valley.

My mom still writes Conn instead of CT.

CTDOT uses Mass in a couple of cases.

I would be curious to know what Iowa's would be. Did they even have one? Since I moved here, every piece of mail my mother has sent me says Mason City, Iowa.

Ohio is sometimes abbreviated as "O.", though I don't have photos on hand.

in 1989 WV used it on a sign in Huntington for the US 52 bridge across the Ohio River.  Do not know if it was on US 52 or even I-64, but Chesapeake, O was written out.

Yes Indy used to use Columbus, O to distinguish it from Columbus, IN which is south on I-65 from there.  Columbus, OH is east on I-70, though both OH and IN now use Dayton as a control city and newer signs reflect that.  A few were still around in 2008 when I was there last.

[tdindy88]

A fairly new sign was installed when they rebuilt the South Split that keeps Columbus OH as the control city for I-70, but this is probably an outlier, still it is a new sign so Columbus will remain the control city at least somewhere.

West Virginia has no rhyme or reason to Ohio.  I have seen "OH" "O" "Ohio" and "Oh".  The rest seem to be the standard two capital letters from the USPS, although the usage is inconsistent.  Sometimes Columbus is just Columbus, sometimes it gets an Ohio, but Washington, a small town in Pennsylvania, is fine by itself in Morgantown, even though the capital of the United States is on the opposite interstate.

Before I-77 and Corridor Q were built in Virginia, Virginia had mileage signs not to Princeton but to "W. VA. TURNPIKE" on the predecessor roads.  Some of these are still around.

[briantroutman]

Lots of "Penna" Turnpike signs still around.

Those aren't merely stragglers. "PENNA"  is still standard for the Turnpike's sign-mounted keystone shields (like this recently installed sign at the I-95 interchange) as well as the insignias used on PTC vehicles, equipment, letterhead, etc.

The PTC does use "PA"  on its numbered non-Interstate markers, however–such as 43 and 66.

There used to be an overhead LGS pull-through sign on the former I-95 near Trenton that used "Penna" as the control "city."

There's also the "New York City - VIA PENNA"   signage at the I-80/I-76 "bump"  in Ohio.

"Huntington. W. Va." is in use on either US 52 or OH 7, or both, just north of the river.

Back in the '50's and into the early '60's the term "Calif." (more often with than without the period) was used in newspapers and magazines in reference to, of course, California.  Obviously not utilized in the broadcast media, it disappeared about the time that the two-letter state references became S.O.P. for more than simply mail delivery.  I didn't hear the term "Cali" until the late '70's; and not commonly for at least another ten years after that.

I'm interested to know if anything exists (doesn't have to be road-related) using the original two-letter abbreviation for Nebraska. When they were created in 1963, Nebraska was NB; it was changed to NE in 1969 to avoid conflicts with New Brunswick.

"Peoria IL." on I-74 in Indiana:

In Flagler Beach, FL, The Pier/Restaurant building still says "FLA"
