Numbered "exits" which aren't really exits

[TheGrassGuy]

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)

[kphoger]

to stay on

I can't remember:  What does the current MUTCD have to say about that type of situation?

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:

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.

[jp the roadgeek]

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.

I believe that would be MUTCD-noncompliant.

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 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.

[kphoger]

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).  In this case, that route appears to be I-59.

[interstatefan990]

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:

Doesn't count because it uses I-59 numbering.

I understand.  But you still aren't exiting.

Yes, you are.  You're exiting I-59.  The angle of the roadway doesn't matter.

[roadman65]

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.

Really? Thanks for gathering me.

Arizona does this at its Sunset Point rest area off I-17 (Exit 252). NB signage, then SB signage:

Exit 880 on I-10 West, Texas Travel Information Center

I think it's the highest exit number in the United States as well.

Exit #502

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.
