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".

NY 298 has them on a traffic circle of all places.

Does Route 9 in Middletown CT count?

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:

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.

I posted this on another thread awhile ago, but US-6's diamond interchange ramps at I-75 near Bowling Green, OH are exits 66 A&B.

Linden Blvd and Grand Concourse in NYC used to have exit numbers for the intersections. The former may have a few stragglers; the latter were greened out 20+ years ago.

The Saw Mill has numberous exit numbers at at-grades.

Also, I have no idea what the deal with this number is on NY 27, but it exists nonetheless.

Maybe the person who designed the sign meant it in a more literal sense, as in "use this slip lane to exit NY-27?"

It was part of a whole sequence on Linden Blvd.

Nova Scotia-

Dunbrack St at Hwy 102

Pictou Rotary on Hwy 106

It is also common for Nova Scotia to assign exit numbers on the 100-series highways at the major at-grade intersections...
(See Hwy 101, Hwy 103, Hwy 104, Hwy 105, and Hwy 107)

US 23 in Ohio has them posted at at least some of its interchanges, though it ain't a freeway:

US-52 between the Twin Cities and Rochester is an expressway but has a mix of at-grade intersections and interchanges.  The interchanges are sporadically numbered.

Eastbound US 20 at the eastern end of US 20B in Toledo, Oregon

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).

Ohio is adding them to all interchanges statewide, whether the road is a freeway or not, as part of sign replacement projects.

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.)

US 60 in Miami, Arizona has Exit 227 on a non-freeway portion of the roadway

And the numbering appears to be based on overall route mileage, despite the fact that they generally post county line based mileposts.
