Not showing up...  until after I saved the link and reverted it.

Garden State Parkway Exit 9 (One of the traffic signal ones) says TO US-9 on it.

Exit 1 on I-287 is for US 1.

Okay, I'll bite...

In Michigan, I-75's exit 69 is Big Beaver Rd.

That should count!!! PLEASE get a picture of that.

Oh and Kudos to whomever can pronounce the town correctly in my link   

Cloo-teeay-vill. (or -veell if you're European)

Exit 60 on Florida's Turnpike used to be for State Road 60 before they renumbered the exits based on mileage. The only other one I can think of is for Exit 57 on I-10 in MS, which goes to MS 57 - but someone above already mentioned that one.

In Columbus:

Exit 104 off I-71 is for OH 104. (Though I don't have a picture)

Exit 23 off I-270 is for US 23.

Interestingly, the same interchange is signed as Exit 23 off of US 23 (though this only counts US 23's mileage in Franklin County)

I was in Columbus two weeks ago and noticed Exit 23/US 23 on 270, and another one.  But until I saw this post, I thought it was somewhere else on 270.  Now, do you know whether Ohio 104 was intentionally given that number so it would match the exit number off 71?

Fayetteville, AR

Lamar, AR

[english si]

Both the A1(M) and M11 have junction 14 with the A14.

M25 junction 2 is with the A2.

M80 junction 9 is with the M9, where it's junction 9 on that road (no streetview as junction number has just changed)

M4 J4A, in a nice bit of symmetry is with the A4

[Central Avenue]

Here's another I noticed while looking through some photos the other day. I-75 near Chattanooga:

I'm fairly certain that OH 104 predates I-71, so probably not.

Not fudged at all.  Exit is also for Frank Rd, sometimes called "Rank Rd" because of a foul odor often experienced near that interchange.

Exit 23 off I-270 is for US 23.

Fudged. Should be exit 24 by nearest-integer rule in Ohio. Probably for the better, otherwise exit 23 and US 23 would be adjacent interchanges.

Interestingly, the same interchange is signed as Exit 23 off of US 23 (though this only counts US 23's mileage in Franklin County)

Malarkey.  The mileage is correct, but as US 23 is not a limited access road at this point (except for the short distance required by the interchange with I-270) these shouldn't be labeled as "exits" at all. I consider those signs to be erroneous.



Are there any pairs of exits along one highway where the exit number for one is the highway number for the other, and vice versa?

I don't understand how it's "erroneous" if the mileage is correct.

I-4 Exit 33 for FL 33. Then, there's the radar-inclined I-95 Exit 244 for FL 442.

Under the premise that US 23 should have exit numbers in Franklin County, then it'sfine (well, almost – ideally, exit numbers should use the state mileage).  I reject that premise, because US 23 isn't a freeway or expressway anywhere near that interchange.  It doesn't have exits, so those guide signs marking entrances to I-270 should not have exit tabs at all.

There are a few places in Ohio where non-Interstates have exit numbers.  Most of them are done wrong one way or another, and this shouldn't even be one of those places.

Write an letter to the editor of the Dispatch then. They love letters complaining about government.

While not quite what the OP was looking for, Exit 264 on I-64 in Virginia is for I-664.
