I'll go first:
Exit 18E to stay on the I-95 / NJTP Eastern Spur (in contrast to Exit 16E for the Lincoln Tunnel)
Exit 1A for I-295 in DC (which is kinda gray because you're on another highway numbered 295; in contrast to Exit 1B-C for I-695)

Nothing, despite the fact that a lot of content relating to toll roads was added in the 2009 edition.
Do mainline "exits" on TOTSOs count? Like this one:

Work started on MA 128 last night in Gloucester, from monitoring Waze reports they got at least to MA 133 (New Exit 53). Here's an article that appeared in yesterday's online Gloucester Times:
https://www.gloucestertimes.com/news/local_news/route-128-exits-to-be-renumbered-thursday-night/article_d4d6036f-2b93-5f00-aca1-fb0d8c315c86.html (https://www.gloucestertimes.com/news/local_news/route-128-exits-to-be-renumbered-thursday-night/article_d4d6036f-2b93-5f00-aca1-fb0d8c315c86.html)
Curious, since it will be handled near the end, is this sign just coming down given 3/4 of it is make-believe anyways...

(14 is a real exit. 11 and 10 are rotaries, and 9 is at-grade. The numbers do not go any lower.)
Exits 101A and 101B are marked for the entrance ramps to I-270 on US 23.
GSP Exit 0 (and formerly 9, 10, and 11)

Looks like it kind of goes off to the right there. At any rate, why make one highway the "exit" over the other? Seems to me like six one way, half a dozen the other.
MA 140 Exit 1 (former and current) and Exits 20 A-B (former 12 A-B). The first is an at-grade intersection; the last two have entrance ramps from signalized intersections.

I guess it is a
slight right, but 59 is the one that is exiting, or it's the one that has the most movement. If they just removed the exit tab it would be much better.

There's a couple of locations where one movement isn't signed as an exit at the end of a concurrency. Here's the north split of I-57/I-70 (https://www.google.com/maps/@39.1479518,-88.5145444,3a,69.1y,66.09h,85.9t/data=!3m6!1e1!3m4!1svKjtms-7R4aVA4Kz-UW-tw!2e0!7i13312!8i6656) as an example. If it had an exit number, the I-70 movement would be signed as exit 163, since this concurrency uses I-57 exit numbers.
Right. I haven't personally looked into the details, but what I've gathered from the forum is that it didn't use to be a requirement to sign an exit number at a system divergence. With the most recent edition, however, it is a requirement.

Which edition are you referring to, the 2009 one or the currently in-proposal one? The I-57/70 example I had above was installed when their concurrency was getting widened to 6 lanes. Think that project was done in 2016 or 2017, correct me if I'm wrong.

I am assuming that I-20 gets the exit number because the I-20/59 duplex from the exit to the AL line follows the I-59 numbering.

errr.... OK, I tried to find a thread, but now I can't find it. Someone, help me out here.
Well, anyway, according to the 2009 edition, the goal is to establish "continuity of interchange numbering ... for only one of the routes" (see
§2E.31 ¶16 (https://mutcd.fhwa.dot.gov/htm/2009/part2/part2e.htm#section2E31_para16)). In this case, that route appears to be I-59.
I-87 Exit 8 is more of the end of the I-287 concurrency than an exit. More lanes branch off as 287 than continue on the "mainline" . The exit also stays at the same grade while 87 heads slightly uphill going into the T-interchange:

Yes, you are. You're exiting I-59. The angle of the roadway doesn't matter.
Anthony Wayne Recreation area on the Palisades Parkway in Rockland County, NY is a parking lot with no outlet to other roads.
In fact it had no number assigned to it until 1987 when the PIP renumbered its exits to remove Exits 1OA and 14A and give US 6 a number which the split for that route had none. The recreation area too was assigned one too with that project.
Exit 116 on the Garden State Parkway is an interchange but no exit.

Incorrect regarding Exit 10; such is an at-grade intersection with MA 127/Eastern Ave. For reasons unknown, Blackburn Circle was never assigned an exit number.
Quote from: PHLBOS on February 17, 2021, 07:01:14 PM
For reasons unknown, Blackburn Circle was never assigned an exit number.
It's not unprecedented. There are two at-grades between Exit 28 and Exit 30 on MA 2, and the cemetery on 128 has no exit number (nor does what I call "Exit 21.05").
It no longer exist but I recall the fmr Exit 191 on I-25 in Colorado was more like a quick turnoff then an exit ramp.
Found this one while randomly browsing GSV: "Exit" 66A left turn from US 6 WB to I-75 SB (https://www.google.com/maps/@41.350877,-83.6251912,3a,23.8y,220.65h,91.72t/data=!3m6!1e1!3m4!1swjlRf1rSrhHF3otD-Vne-w!2e0!7i16384!8i8192). Same with 66B on the EB direction for I-75 NB.
The "Burnsville Split" in Minnesota, where I-35 northbound divides into 35W and 35E.
At that interchange, 35W is signed as Exit 88A (doubtless because 35E continues the exit numbers from I-35, while 35W has its own series of exit numbers).
However, as can be seen from this Street View (https://www.google.com/maps/@44.7364058,-93.2831765,3a,75y,357.87h,96.68t/data=!3m6!1e1!3m4!1svngNK7uMev8bJk_ttFhPSg!2e0!7i16384!8i8192), 35W is clearly the dominant roadway, while 35E exits off of it. Because of this (and because 35W came through first - at least, I think so), I think that MNDOT should have given the "default" exit numbers from I-35 to 35W, with 35E using its own numbers.
(In fact, that would be a fun exercise on the "Minnesota Notes" thread or the "Fictional Highways" board: list the exits on 35W and 35E and renumber them as if 35W, rather than 35E, had the "mainline" I-35 exit number sequence assigned to it.)
^ Yes, 35W predates 35E and 35W serves the higher-populated city of the Twin Cities (both reasons why it appears to be more dominant). But as with the 20/59 example upthread, the mileposts follow 35E, so 35W gets the exit number.
The exits on the arterial portion of NY 9A in Manhattan uses numbers at major intersections.

If you flip the script to the Forest Lake split, it's 35W that both has an exit number and is the route that "exits" from I-35. So there's that angle too.
