This is inspired by someone's suggestion that IL 394 be turned into I-394 and I responded that even though part of IL 394 is a freeway, its control city is Danville and people might mistakenly believe that they could take an all-interstate route to Danville by following 394.
This led me to the following question: Is there anyplace in the US where a control city is signed on an interstate but you can't get to that city via interstate by going that direction?
I-65 north doesn't go to Chicago, but you can get to continue to Chicago on interstates, so that doesn't count.
I-69 north at Bloomington has a control city of Indianapolis, but if you head north you have to leave the interstate system to get there.
However, this is only a temporary situation as the rest of I-69 has construction either underway or planned to start soon.
Is there a more permanent example anywhere?

I don't know enough about Canada's highway system. If someone follows a sign for Montreal, are they going to stay on interstate-grade roads? That's really the spirit of what I'm getting at.

There's a gap in the extension of I-89, which is planned to be filled in, but I-87 has a full freeway connection.

Vancouver BC is not quite served by a freeway-grade connection directly from I-5, since Hwy 99 is an expressway when it crosses into the southern city limit and immediately begins its street section.
I-182 has Walla Walla signed as a control city in a few spots, but obviously doesn't reach that far. US 12 continues there but isn't a full freeway, though one may be built eventually (about half is now expressway-capable).
Not a specific city. but Minnesota's closest qualifier is I-35 northbound using "NORTH SHORE" on pull-throughs starting at Cloquet. I-35 ends in Duluth and you continue up the shore on TH 61.
Of course, Duluth is on the North Shore in the strictest sense even as the term generally refers to the areas beyond Duluth, so...
I-70 eastbound's control city is Baltimore, but–

At the I-75/I-275 split north of Monroe, Michigan, the control city for I-275 is Flint.
To get to Flint via I-275 from here requires taking I-275 to its end, then I-96 to Brighton then US-23 to Flint.

No, because you continue onto I-10 to make it to New Orleans
Just like in the OP, I-65 has a NB Control of Chicago, but ends in Gary, IN. But drivers can use either I-94 or I-90 to continue to Chicago and still be on the Interstate System
The question here, is an Interstate Control that is NOT (directly) reachable by going in the direction of the Control via Interstate Highways (regardless of number)

These examples qualify, yet at the same time they are near where the interstate ends so just about any city you would use as a control city is going to qualify.

Does I-90 in South Dakota have any distance signs for the state's capital of Pierre? That was the first one that came to mind for me - it's about 20 miles off the interstate on US 83.

The Bay Area has one. I-880 has Santa Cruz as a control city which makes sense because when I-880 ends the freeway becomes CA-17 which terminates at Santa Cruz. But otherwise you can't get to Santa Cruz from San Jose without going through a windy expressway!

If the future US 412 interstate between I-35 and I-49 uses Enid as a WB control city, it would be a similar situation as I-76.
There are signs for Boulder on I-270 West, but you can't get there via interstate, only US36.

In Hawaii, Interstate H-1 has Waianae as a control city. Waianae is well beyond H-1's west end, on non-freeway Hawaii route 93.
Does an unsigned interstate count?
In Grand Rapids the exits from I-196 to unsigned I-296 nb have Cadillac as the control city.
Similarly, I-96 exits to I-296 sb have Kalamazoo.
Of course, it's really just US-131.
Control cities actually don't have to be reached before they change. For Michigan though all control cities are reached via interstate.

If you were going to stay on Interstates to get from Monroe County to Flint, you wouldn't take that I-275 exit. I mean you could, but from there to Flint it's much shorter staying on I-75 through Detroit than it would be to use I-275 to I-96 through Lansing to I-69 back to Flint.

The whole point is if you take I-275 could you get to Flint using all Interstates? I'd say the answer to that is yes. However Flint is an old control city on the list which probably should be updated. I'd say use Livonia

These examples qualify, yet at the same time they are near where the interstate ends so just about any city you would use as a control city is going to qualify.
This example has all the Phoenix signage near the beginning of the route southbound, not the end. Granted I-515 is less than 15 miles long now (and was only about 20-ish miles in length before the south end was rechristened as I-11), so your point is still valid.
I-66 is signed for Front Royal, but does not enter the Front Royal corporate limits. Access is by way of non-freeway US 340/US 522 and VA 55.
Also, this is technically cheating, but I-64 uses Colonial Williamsburg as a control city but obviously it does not enter Colonial Williamsburg (or even the City of Williamsburg), and one has to use surface streets to make the connection.

Quote from: interstate-guide.com
I-595 in Maryland is the longest unsigned route within the Interstate Highway System. Aligned entirely along U.S. 50 (John Hanson Highway) and partially along U.S. 301, I-595 follows John Hanson Highway between I-95/495 (Capital Beltway) and MD 70 at Annapolis.
According to interstate-guide.com, I-595 makes it to MD 70 in Annapolis. And since one can continue from the southern terminus of I-97 onto Hidden I-595 to reach Annapolis, Annapolis is reachable via Interstate Highway from I-97
In the Green Bay Area, Marinette is used as a control city for I-41 north.
