The northbound exit ramp from I-95/128 to I-90, MA 30, and Recreation Road in Weston MA is presently numbered as EXITS 23-24-25. Which raises a question posed to my supervisor by her son earlier. Are there any locations in other states where a single exit ramp serves three separately numbered (as opposed to a single number with suffixes) exits, and is signed as such?
I-290 exits 19-20 in MA.
I-84 exits 62 & 60 in CT.
I-495 exits 12-11, 44-43, 44-45, and 49-50 in MA.
I-93 exits 47-48 in MA.
MA 3 exits 19-18.
That's all I can remember right now.
I-264 exits 13-14-15 (https://www.google.com/maps/@36.841981,-76.2169223,3a,75y,87.22h,84.55t/data=!3m6!1e1!3m4!1syQMd8mGdoe-Qd7nEWEhAmw!2e0!7i16384!8i8192!5m1!1e1?hl=en) for US 13/I-64/Newtown Road in Norfolk/Virginia Beach.
EDIT: Can't believe I didn't think of the I-95 exits 31-32-33 one below, it was on my commute pre-COVID :-D
I-95 NB exits 31-32-33 in MD (https://www.google.com/maps/@39.063997,-76.9129819,3a,75y,58.96h,90t/data=!3m7!1e1!3m5!1sjwL9XGtbHhr6v-EU37M8Eg!2e0!6s%2F%2Fgeo1.ggpht.com%2Fcbk%3Fpanoid%3DjwL9XGtbHhr6v-EU37M8Eg%26output%3Dthumbnail%26cb_client%3Dmaps_sv.tactile.gps%26thumb%3D2%26w%3D203%26h%3D100%26yaw%3D52.226395%26pitch%3D0%26thumbfov%3D100!7i16384!8i8192)
On south I-355, just outside Chicago, there's this, which consists of a service exit to IL-56, and system exits to east and west I-88.

ETA: I take it back. Both east and west I-88 are part of exit 20.

Those are all two separately numbered exits from a single ramp, not three. As your list shows, that's actually fairly common.

You can make an argument for I-84 Exit 62-60. There is a bonus (unnumbered) ramp for I-384 East contained within the interchange, which can serve as an alternate to Exit 59.
You also currently have Exit 35 A-B-C (soon to be 89 A-B-C) on I-495 in MA.

Is it really a "ramp", though? Looks more like
a really long C/D road (https://goo.gl/maps/M4X1GzpUHn7Y5i9H6) to me.
In fact, there's little functional difference between it and the "ramp" to the lower level of I-35 in Austin serving (1) 38½ St, (2) 32nd St, (3) Manor Rd, and (4) 15th St.

Both the OP's example of I-95 MA exits 23-24-25 (https://www.google.com/maps/dir/42.3335264,-71.2556383/42.3432612,-71.2628373/@42.3420479,-71.2564,15z/data=!4m2!4m1!3e0?hl=en) and odditude's example of I-95 MD exits 31-32-33 (https://www.google.com/maps/dir/39.0647482,-76.9116732/39.1073112,-76.8824264/@39.0830973,-76.8990775,14z/data=!4m2!4m1!3e0?hl=en) are also lengthy C-D roads, FWIW.
But you raise an interesting point there with C-D roads connecting multiple interchanges versus a true offramp with 3 numbers.
If it counts C-D routes, then what about the express vs. local lanes on ON-401 in Mississasuga and Toronto?

That seems like a rather arbitrary distinction. In Wisconsin, two or three exits' getting different numbers
vs letters appended to the same number depends on where they are in relation to mileposts–not on how they or the exit ramp -slash- C/D road functions w/r/t the main highway.
To put it another way: If your I-95 #23-#24-#25 example were converted to mile-based exit exit numbering, then you would stop counting it? Even though nothing else about it had changed?

Two, not three.
Looking at C/D lane examples (basically all of them in this thread so far?): none in WA would qualify, since the C/D lanes are usually signed as exits themselves.
For example, on northbound 5 just south of the Seattle CBD, exit 164A (https://goo.gl/maps/qWqLpRsfDuNCiy1v6) leads to (1) James Street, (2) Madison Street, (3) Dearborn Street, and (4) I-90 eastbound. After the gore, all of these are just signed as splits.
In Tacoma, on northbound 5, Exit 132 leads to (1) S 38th St eastbound, (2) S 38th St westbound, (3) WA-16, (4) southbound WA-7, and (5) northbound I-705. Again, all of these are signed as regular non-numbered splits after the exit.

I don't think it does; the original post says that the exits have to be separately numbered. That being said, since Wisconsin uses milepost-based exit numbers, it would take a ramp at least a mile long to serve 3 separately numbered exits.

The original question posed to me was "Are there any single-ramp exits that have distinctly separate numbers (i.e. 23-24-25). That is why I excluded numbers with suffixes.
Quote

The I-95 #23-24-25 example I cited is becoming Exits 39B-A ** under the pending MassDOT milepost-based exit renumbering. So it will no longer count once the number is changed.
** As the Recreation Road exit is planned to be closed within the near future as part of a private development project in Newton, it was decided to remove the number at this time. Note that the only reference to Recreation Road on the I-95 northbound mainline is a single ground-mounted sign. Also, the 'reversed' northbound suffixes are so the I-90 (Exit 39B) and MA 30 (Exit 39A) exits will have the same numbers northbound and southbound.

Eastbound is 198 A/B and 199. 198A goes to the Airport and 198B goes to Merriman Rd Northbound. 199 is Middlebelt Rd.

US-50/John Hanson Highway/Unsigned I-595 in Bowie, MD.
Exit 13A - US-301 SB
Exit 13B - MD-3 NB
Exit 13C - Control city is "Melford", and also lists Belair Dr. The former is mostly a newer industrial park. It used to be signed "Univ. of MD Sci/Tech center", with a "Future" banner added and then removed within like a week.
So one exit serves a US Route, one a State Route, and one unnumbered road. And that's from an unsigned Interstate!

Make them lowercase.
α is the fine structure constant, which is approximately 1/137. Greek Α (the capital form of α) looks identical to Latin A.
Cyrillic б is the equivalent to our letter b, and it looks like the number 6. (Uppercase Б looks much less like a number.) However, Cyrillic also has a В/в, which is our V, so you have to go by transliteration, not look-alikes.
c is the speed of light, but lowercase only, just like the other two. Unlike the other two, it's a number with units, not just a plain number.
I guess this thread has officially derailed. :bigass:
