This thread: https://www.aaroads.com/forum/index.php?topic=27394.0 , along with a discussion last night about sharp-turn exits from freeways, got me thinking about something. How common is it to have exit numbers for at-grade intersections, whether they're on Interstates or not? Most of us know that the Garden State Parkway used to have a few of these toward the southern end, but I'm not sure if any remain besides Exit 0: https://goo.gl/maps/WeGJcZ6yRzA1mcEU6
But then, you have the occasional at-grade intersection on an Interstate highway, whether it's RIRO or allows cross-traffic. Exit 106 on I-25 in Colorado is a pair of RIRO T-intersections: https://goo.gl/maps/YWryP7uXmsk9u2z78 , https://goo.gl/maps/stVdZ1B9y64gTgeb9 , https://goo.gl/maps/xcff2rSQwzr53Jcz9 , https://goo.gl/maps/ZFBAYfn7xPGaXPXKA (not sure what happened to the camera here).
What others can we add to the list?

Oh, I forgot some! Some of those goofy, blue-signed exits on US 69 in McAlester, Oklahoma are merely at-grade turns:

Nova Scotia has a fair number of these on some of the 100-series highways (the one I particularly recall is NS-103 heading east out of Yarmouth parallel to the smaller roads that make up the Lighthouse Route tourist drive, but that route is not unique in the province in this respect). Here's an example: https://goo.gl/maps/hTvX4ckGQfPQ3gRE6 (the "exit" is where that car is coming from the left up ahead).
Note that while in the above-referenced example the left-aligned exit tab complies with the convention with which most of us are familiar, it seems like Nova Scotia left-aligns all exit tabs regardless of where the exit is and the type of road. Consider this one on NS-103 for a crossroads near Shelburne (https://goo.gl/maps/hHySUC6ejgCaG6RA7) or this one on a freeway-grade section of NS-104 (https://goo.gl/maps/rPHNU96sXr585LcMA).
I-83's southern terminus at Fayette St in Baltimore is signed as "exit 1" (https://www.google.com/maps/@39.2969343,-76.6112922,3a,44.5y,174.32h,91.71t/data=!3m6!1e1!3m4!1s6FgyGlqullyXWZJTIkrjXQ!2e0!7i16384!8i8192!5m1!1e1?hl=en).

this isn't far from where i live. but that is absolutely bananas.. seems like a terrible idea, since we know no-one ever speeds in this area.

Are those at-grade intersections, or are they normal exits where the only thing signed is the exit number?
The West Side Highway (NY 9A) in Manhattan signs several intersections with exit numbers: https://goo.gl/maps/VEyLdThyRwUsP5AX9
And there are some at-grade intersections on the Saw Mill River Parkway in lower Westchester, NY that have the same (bonus LEFT exit tab): https://goo.gl/maps/PqzDDqLtV7ZnnuAA9
Almost forgot this one: I-70 exit 147 in PA (https://www.google.com/maps/@39.9771567,-78.244859,3a,75y,14.81h,89.07t/data=!3m6!1e1!3m4!1sMpvtdAkC3jM9iHy45F3gnQ!2e0!7i16384!8i8192!5m1!1e1?hl=en)!
Not sure if this meets the topic at question but here's my example.
EB I-495 Long Island Expressway Eastern Terminus in Calverton/ Riverhead NY is signed as Exit 73 even though the expressway essentially just squeezes down to one lane and merges into CR-58.
https://goo.gl/maps/hQPyJXhiCS2h2FPJ8 (https://goo.gl/maps/hQPyJXhiCS2h2FPJ8)
Here's an at grade intersection at NY-347 & NY-111 in Smithtown NY. There's no exit number but there exit tab for N-S as there's a connecting ramp for all turns onto 111 to avoid turn movements at main intersection of 111/347. There a similar sign in opposite direction as well.
https://goo.gl/maps/9dvPrp83DQbb78268 (https://goo.gl/maps/9dvPrp83DQbb78268)
In Norwich, CT 2 exit 26 at Yantic Lane was at-grade. This was eliminated when the 2/32 interchange area was reconstructed in 2001.
Can't recall off the top of my head, but didn't the at-grade portions of NY 17 between the Thruway and Binghamton have exit numbers?
I vaguely recall this being the case on US 98 (maybe US 98 Business?) in Panama City, FL back in the '90s.

But it's the exit ramp numbered, not the intersection.
US 98 in Bay County, FL used to have numbers.
US 258 in Hampton, VA used to have letter exits at service road crossovers back in the 70's.
NY 9A in New York City does left over from Miller's Westside Highway.

not sure if this qualifies.. but it seems like its in the ballpark..
co-115 in colorado springs.. is a 2-lane all the way from penrose to near fort carson. then, shortly after a traffic light, there's a sign for exit 40-something.. and the road becomes a semi-expressway for a little bit, before turning into (where's the southern colo guy?) nevada street?
https://goo.gl/maps/hDD6JTSBYqijFu3Y7 (https://goo.gl/maps/hDD6JTSBYqijFu3Y7)
you might have to zoom or pan this around to see the sign.. google maps is really kicking my butt today for some reason.
its not at grade per se.. but close..
Doesn't NY 9A/the West Side Highway in NYC have some intersections like this (at grade with exit numbers)? Maybe FDR Drive as well? Anyway, when I saw the thread title, that was the first thing that came to mind for me.

Mentioned twice in the thread already.
I believe the most common examples are on I-10, I-20 and I-40 in TX.

Ever since it corresponding cloverleaf movement was removed, I-55 South Exit 12B in Memphis has been converted into a left-turn intersection. While it's on the off-ramp, it still has an exit number: https://goo.gl/maps/AWzU2cG4q3QJMnLn9

Crap. That used to narrow down to two lanes. And no, that doesn't count.

Your version was a zoom onto the asphalt.
I still remember at grade exit numbers on North Road(Suffolk CR 48, formerly CR 27) on the North Fork of Long Island, and on Suffolk CR 39 east of the end of Sunrise Highway, when NYSDOT was still hoping to move it on the extension east of Shinnecock Hills. Sadly though, I can't prove that they existed back then.

I've probably seen the advance sign for that, but I forgot all about it. That one makes more sense than a lot of the others.

None are at-grade intersections. Some in Wyoming have off-ramps posted for 10-15 mph exit speeds, but traffic on the local road passes over or under I-90.
Exit 16 and 17 (future 23D and 24) on CT 9 in Middletown.
Although signage for such have largely gone by the wayside; MA 128 through Gloucester still has numbered intersections and one rotary... at least on paper.
9 - MA 127A intersection... MA 128's terminus
10 - MA 127 intersection
Blackburn Circle was not assigned an exit number
11 - MA 127 Grant Circle
Such has existed since 1962. Note; MassDOT plans to drop these exit numbers for the above when 128 converts to mile-marker-based interchange numbers in the foreseeable future.
One sign that lists the above-exits (https://www.google.com/maps/@42.604087,-70.7423282,3a,75y,69.72h,82.63t/data=!3m6!1e1!3m4!1sen-9EWkhTjYTjBwwp-Z3pg!2e0!7i16384!8i8192). Still there as of 2019.
Only remaining sign that the approaching Grant Circle is Exit 11 (https://www.google.com/maps/@42.6223491,-70.6798691,3a,75y,126.58h,75.97t/data=!3m6!1e1!3m4!1spX41WaPJYYHqh8ZkNNpOVw!2e0!7i16384!8i8192). Again, still there as of 2019.
Many semi-examples can be seen on the US 50 freeway in Maryland, in the Annapolis area - many of them *technically* have ramps, but they are so short (and the turns so tight) that they are at-grade intersections for all intents and purposes. The signs seem to indicate as much - notice that many of them use an arrow pointing straight right (or up and right) as opposed to the normal angled arrow.
An example from Street View (Exit 38A for Thompson Creek Road): https://www.google.com/maps/@38.9771093,-76.3141553,3a,37.5y,105.9h,93.85t/data=!3m6!1e1!3m4!1s2b4cMNbukzuOTk5g1u9qtQ!2e0!7i16384!8i8192
(It doesn't even pretend to be a traditional freeway exit - in fact, there is even a "right turn" marking on the pavement!)
The Garden State Parkway used to have three of them in Cape May Courthouse, NJ before the NJTA had them all interchanged.
North of the border, I think I once read that there's a parkway-type road on Vancouver Island that marks some intersections with exit numbers. (Any users from BC, or who have visited, that can verify this?)

Some tighter ramps that are true exits can use these straight right arrows as well.

While it indicates a right turn here, many auxiliary lanes on interstates with true ramps also use right turn pavement markings. It's not uncommon.

Exit 1 of I-95 (now Exit 76 of I-295), southbound, used to be like that. It had the same horizontal right arrow, and the same pavement markings.

How could I forget the exits for KY 66 and KY 118 on the Hal Rogers Parkway?
Until the mid-1980s, the Orleans Rotary on Cape Cod was labeled as US-6 "Exit 13 N-S"
Exit 13S - MA-6A West/28 North
Exit 13N - Rock Harbor Rd
If they were still numbered, the renumbering project would have killed it, but if it was ever to be reconfigured as an interchange, it would likely be Exit 91.
