Locations where three separately numbered exits are served from a single ramp

[kphoger]

I-64 Westbound (heading east) in Chesapeake, VA for Exit 291 and Exit 290.

I count six exits (with three numbers) that can be reached before that C/D road rejoins the mainline:

#291B – VA-168 SB (exit is after the double-white roadway split)
#291A – I-464 NB
#290B – VA-168 SB
#290A – VA-168 NB
#289B – Greenbrier Pkwy SB
#289A – Greenbrier Pkwy NB

Exit 289 isn't counted on the aforementioned exit signage since there is an additional ramp for it from the mainline between Exit 289 and Exit 290.

I know.  But it's still served by that exit, notwithstanding lack of advance signage to that effect.

Does exit 135 A-B-C on I-39/90/94 NB/WB in Madison WI count?

I tried to show it in Google Maps, but the street view feature is missing.

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.

In Minnesota, Exit 3 on I-394 serves three exits, but only the C/D ramp exit is numbered and the two US 169 ramps along with the General Mills Blvd exit are unnumbered within the ramp.

Another example is this on I-94 for exit 199/198 https://www.google.com/maps/@42.2453527,-83.3171413,3a,75y,250.18h,89.71t/data=!3m6!1e1!3m4!1s-sd5sHD6Tmoo2kvc2TUwlA!2e0!7i16384!8i8192?hl=en

And they're backwards.

No, because it is a single number with three suffixes, not three separate numbers.

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.

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.

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?

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.

That only serves two exits, doesn't it?

Eastbound is 198 A/B and 199.  198A goes to the Airport and 198B goes to Merriman Rd Northbound. 199 is Middlebelt Rd. The eastbound sign is correct in how the numbers goes up. https://www.google.com/maps/@42.2363623,-83.3515192,3a,75y,74.64h,98.24t/data=!3m6!1e1!3m4!1sQgtPGc5U6xyqbcJqLdi9nw!2e0!7i16384!8i8192?hl=en

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!

Since when did A, B and C become numbers? Unless highways are using hexadecimal these days.

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.
