Title: Exit Numbers on non freeways

DE SR 141 uses them at an interchange with US 13/40 with the designation being a city street.

I know NY 9A in New York City uses them on West Street / 12th Avenue that is a wide boulevard.

Any other places.

US-30 has a one-off interchange that was numbered in 2012, but only in one direction. The other direction has an unnumbered exit sign, but guide signs say "RIGHT" instead of "EXIT".

I-78, I forgot, in New York.  It's not freeway exiting the Holland Tunnel but around the Holland Tunnel Rotary it's is numbered where the ramps departing that circle are located.

This is my one of my favorites.  On the Central City Parkway between I-70 and Central City, CO.   It is a connector road which goes to the casino towns of Central City and Black Hawk.

This is the only "exit" along the parkway, and they don't even name the street the exit leads to (Lake Gulch Road).

I know in Newark, NJ the NJ Turnpike didn't assign information SB to Exit 15 E until recently. It was just Exit 15 E on guides with no mention of US 1 - 9 or Newark and Jersey City.

US 395 north of the CA/NV border is not a freeway.  It's a four-lane expressway with at-grade intersections from the state line up to a point just north of Hallelujah Junction.  The interchange with CA 70 is grade-separated, though, and it gets the only exit number anywhere on US 395 in California:

https://maps.app.goo.gl/nXzwqXsGhuJvhvGE8 (https://maps.app.goo.gl/nXzwqXsGhuJvhvGE8)

There are a few grade-separated interchanges on California's southern US 395 between Topaz Lake and I-15 (example:  the interchange with CA 203 at Mammoth Lakes), but none of those get exit numbers.

Very strange for an at-grade intersection.

There's also one on westbound OR 18 at the eastern end of OR 18B, but at least that's an actual exit:

IIRC, the Taconic State Parkway's old exit numbers were assigned to both at-grade intersections and actual exits. The first exit numbering scheme (which has been gone for decades now) had sequential numbers with a preceding letter indicating the county - so Putnam County's exits were P1, P2, P3, etc., Dutchess County's were D1, D2, D3, etc. This was more-or-less abandoned for a long while before mile-based exit numbers finally showed up in recent years. Before mile-based numbering showed up, some of these numbers still hung around as small rectangular signs on the signposts for crossroads, but I don't know if any are left (especially since many of those at-grade intersections have been limited to RIRO or eliminated entirely).

US 30, west of Clatskanie. https://maps.app.goo.gl/AXWnDjiodDy9jJeZA

Also a rare example of a double non-conformity for Oregon milemarking -- US 30's zero point should be at US 101 in Astoria, but zero is at I-405 in Portland, at the southern end of the north-south run from Rainier to Portland, and north-south highways zero points should be at the north end, not the south end. This interchange is 73 miles from Portland.

So this should really say EXIT -73.

So is it the case that Oregon signs non-Interstates west to east like Interstates, and north to south opposite the Interstates?

Yes, BUT

Mileage isn't tracked for a signed Route; it's tracked for the underlying Highway. Using OR 22 as an example: It has Exit 16 at OR 99W, and a new sequence from 1 to 13 starting at I-5. Its mile posts are 1-25 (ORH 32 from US 101 to OR 18), 1-26 (ORH 30 from OR 18 to OR 99EB), and 1 to 81 (ORH 162 from I-5 to US 20).

There is one N-S Route that follows Interstate convention, and it's coincidental: OR 35. Its Highway (26) actually starts at OR 99W in Portland along US 26; OR 35's milemarkers are 57 to 101 from US 26 on Mt Hood to US 30 in Hood River. (US 26 has the first 57 miles of ORH 26, and the following Highway US 26 follows, 53, continues the sequence as well down to US 97 in Madras.)

Overall mileage markers (the 2/10 ones) are appearing on non-Interstate routes in Ohio; US 35 in Dayton has had them with the mileage to the Indiana line for quite a while.  The exit numbering on non-Interstates in Ohio has been going for 20 years now, but will take forever to get everywhere at the pace they are going because it seems to be dependent on district.  Two sign replacements on US 30 between I-75 and the Indiana line in that timeframe have yielded no exit numbers at all, while exit numbers have appeared on US 30 in Mansfield and Massillon (crapping out near Canton, with an exit numbered eastbound but not westbound).  Ostensibly it is because the sections in Mansfield and Massillon are freeway, but that hasn't stopped them from posting exit numbers on other roads with one-off interchanges. 

The strangest-looking instance of exit numbers on a non-freeway in Ohio has to be on US 20/23 at OH 420; the full-width gantry with two BGSs with exit tabs over a two-lane road just comes out of nowhere.  (The road does widen to a dual carriageway at the interchange.)

I don't really get how OhioDOT decides which exits get exit numbers with sign replacements, and which don't. Three examples in the southern half of the state:

US 35: Exit numbers added on most the interchanges east of I-675. A bit head scratching for the exits west of I-675, as the signs look like they were replaced just 2-3 years ago.

US 23: Exit numbers added in Chillicothe area, with US 23's exit numbers taking continuity on the concurrency with US 35. I actually thought US 35 will get exit number continuity here, as it's a freeway for longer and leaves the concurrency on the left on both ends, but sure. However, no exit numbers further south, including the new interchange with OH 823 in Portsmouth.

OH 32: A new interchange that opened late last year just west of the US 68 interchange was numbered Exit 27. Further west, there are two other new interchanges (to Glen Este-Withamsville Rd and Bach Buxton Rd) that don't have exit numbers assigned, nor have any existing interchanges got exit numbers. Also, OH 32 between I-275 and Batavia doesn't have any of the blue enhanced mile markers either, unlike every other freeway in the Cincinnati area.

The Avenue of the Saints is only sporadically controlled-access from Clear Lake, Iowa all the way to St. Louis, but all the exits in Iowa are numbered. Unfortunately the route changes designation several times, leading to duplicate exit numbers and a couple switches between exit numbers increasing and decreasing as you travel along.
