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

[roadman]

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 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

[odditude]

I-95 NB exits 31-32-33 in MD

[CtrlAltDel]

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.

Shoot. I read that thread title too fast.

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.

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

No worries.

I-264 exits 13-14-15 for US 13/I-64/Newtown Road in Norfolk/Virginia Beach.

Wow!  This one ought to count as 5 exits included in a single ramp, as 13 and 14 are both split into A and B exits!

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 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 and odditude's example of I-95 MD exits 31-32-33 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.

[ethanhopkin14]

If it counts C-D routes, then what about the express vs. local lanes on ON-401 in Mississasuga and Toronto?

Or I-90/94/Dan Ryan Expressway on Chicago's South Side

I had that thought when I first read this thread, but I don't think that is the general idea of this thread

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.

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?

Working fine for me.

Exit 135C-B-A

[sprjus4]

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

I-264 Eastbound in Portsmouth, VA for Exit 6 and Exit 5. This one isn't a C/D road, but truly a single ramp for two separate exits. Further up, this is the ramp split.

[cwf1701]

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

That only serves two exits, doesn't it?

Two, not three.

[jakeroot]

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 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.

[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.
