Signed "City Routes"

There's a difference, though. NY 9P is just a generic suffixed route, it doesn't stand for anything. It's very probable that OK 412P also stands for parallel.

It's very probable that OK 412P also stands for parallel.

Then what the heck does this mean?

My best guess is that it means link. I would assume that this old alignment was kept under state maintenance all the way to Jackson Boulevard for a number of years after I-90 was built. Under this logic, the entire route would be an alternate of U.S. 14A back to I-90. Since 14A is already an alternate route, the 14L designation means the road is a link from I-90 and U.S. 85 to U.S. 14A.

There's an OK 412P near Fair Oaks that is a spur off of US 412.  It was once OK 33P.

that's a state route.

It is?  Here, I had thought it was a US Federal route.

Nope.  It stands for "port" as it leads to Port 33 (which wasn't renamed when OK 33 became US 412).

Why Jackson? It's just a city street?

Not Jackson - Yankee is the city limits per the Goog.

The point is that I believe it used to connect with both U.S. 14A and I-90.

Arkansas used a C suffix for these. There might be one or two remaining on state highways.

There are some segments that are still cataloged in the AHTD inventory as Highway x, section yC, but they are signed as Highway xB.

What happened to your post's title?

So then it would have gone to the 14A stoplight?

Yes it would have. I thought this was at Jackson, which is why I mentioned it.

Oh, OK, thanks! (That's what Google Maps says, bu they're wrong)

NY 9P loops around a park, so that could have something to do with it.  It could also just be a coincidence.  There was a thread recently about the letter-suffixed routes in the area, and it turns out that there was a time when US 9 had almost all possible suffixed routes.
