The Airport Expressway linking the Seattle-Tacoma International Airport to State Route 518 does not have an official name nor is it signed as anything but "Airport". No numerical designation either, as it's maintained by the port and not the state.

That's true enough, but neither designation is posted, nor is it known to the public. The exit from the Walt Whitman Bridge calls it 130/168/676 and from 676 it's 130/168 (without any TOs), so it is signed as a very long exit ramp. From 168, it *is* signed as TO 76/676 and it has exits that are marked as such (but not numbered) which implies it has its own identity.
The very short stretch of "Route 53" between Dundee Road (IL-68, where IL-53 exits) and Lake-Cook Road might qualify. It neither has a name, nor a marked number (maybe an IDOT internal number).
The Newark Airport/I-78 "Connector". Runs from Exit 57 on I-78 to US-1&9.

How about Exit 3A off of Peoria's I-474 in IL?
It is supposed to be part of IL 336 if that route is ever constructed between Peoria and Macomb, and I believe IDOT has a hidden designation for the present short route, that is signed as "To IL 116" off of I-474 and "To I-474" from IL 116 and Maxwell Rd
It basically serves as a long Exit Ramp between IL 116 and I-474 at this point
Per billburmaster.com, it is hidden IL 905 - only signed on IDOT County Mile Markers
http://www.billburmaster.com/rmsandw/illinois/misc/il905.html
There is also "NJ 90" in PA. It's referred to as such (with and without a "TO") from I-95 and has an exit in the state, but there is no signed PA route number for it. hey are also building a second exit on it Westbound.

IIRC the new signs will feature "To", so it won't even be truly signed NJ 90 anymore. They did mess it up a bit, it says "To NJ" next to an NJ 90 shield. Maybe they intended for these to be read separately, but to us roadgeeks it looks redundant. I don't know what signage will look like from the Adams Avenue connector; presumably similar to the signage from 95.
1. The short portion of the Bradley Airport connector after CT 20 leaves/joins it. It's internally known as SSR 401, but it's a piece of an expressway and not signed with a number.
2. The Maine Turnpike connector in South Portland
3. The short Super 2 to the International Ave Bridge/NB 1 in Calais, ME
4. The TF Green Connector

Which makes sense to me, in terms of Travel Mapping's purpose. No one is going to clinch I-76 or I-80 by teleporting onto/off of the overpasses.

The difference of using the Double Trumpet vs the Cloverleaf. The I-74 and I-80 bump in IL does not have this issue, because of maineline I-74 West and I-80 East using 2 of the 4 Loops, so at least 1 direction of travel on each designation is on the freeway section thru the entire interchange
IL's other bump, I-64 and I-70, has I-55 continous thru the bump, so no undesignated section there

Bumps like that shouldn't count regardless unless it's a significant length. 1/4 mile isn't a significant length, especially because, for all intents and purposes, DOTs usually consider designations to swap at a single point because that's how mileposting is done. The only case I can think of where a freeway section within a bump is actually not either of the two involved routes is I-87 and I-90 in NY (Thruway Exit 24), where the 1.4-mile portion of the Thruway without a signed number is NY 915H (though you wouldn't know that unless you read the logs). Exit 24 is (and should be) treated as a trio of partial interchanges because two of the legs are quite long.
But something like Ohio Turnpike Exit 218? Even if the designations followed the ramps, we're splitting hairs if we say the portion of mainline inside that trumpet is unnumbered (BTW, at least one side carries a number at all times because of where the ramps come in). And even
then, the road still has a posted name (Ohio Turnpike).
One that is closer, are the ramps from I-294 North to I-88 West and from I-88 East to I-294 South
It certainly functions like a long Interchange pair of ramps, but there is an Exit on the I-88 East to I-294 South side, the I-88 Exit for York Rd
It is undesignated, but is it a freeway section? Or just a long ramp? I think this is actually longer than the Peoria example I posted earlier
Quote from: ilpt4u on December 10, 2018, 05:03:15 PM
but there is an Exit
The presence of an additional exit in the middle of an interchange shouldn't qualify the ramps as their own highway corridor. If that were the case, then the otherwise-simple
trumpet interchange (https://goo.gl/maps/yAwFneLPuTq) of I-135 and K-96 here in Wichita (with a southbound exit to 29th/Hydraulic) would somehow be its own corridor. Sure, it's a lot shorter than the Illinois example but, then again, that's kind of my point.

I guess, Historically speaking, it was a part of Toll US 30, which would have used the ramps to transition from the Tri-State to the East-West/now Reagan Tollway.
So at one point, it was numbered and designated
Found another candidate, looking at the Mass Pike (why? I don't know). Its also the first quadruple Trumpet Interchange I think I have ever seen...
But there is a limited access roadway running East-West between I-91 and US 5, just north of the Mass Pike/I-90. The roadway has Trumpets with I-91 and US 5 on each end, and has a standard Turnpike-style Double Trumpet for the Mass Pike/I-90 in the middle

It would not. It was a separate segment of I-465.
I posted on the Interstate ends on the 180 spur and there is also a post about the end of 290 into Illinois 53 but didn't mention the unsigned end. I guess IDOT didn't want part of Lake Cook.
Well, this is interesting. Today I learned Kansas City International Airport's connector freeway is technically Cookingham Drive: https://goo.gl/maps/sFUE1Ey3cWpsVVTH9 . But you wouldn't know that from I-29: https://goo.gl/maps/nSUL8pPZbx6QiB4QA . And I'm not even sure where Route D officially ends, either: https://goo.gl/maps/s34hmV2zxZUgHTpB7 . And to make things weirder, Google Maps shows the road named as Cookingham Drive, NW 120th Street, NW Mid Continent Trafficway, and then Cookingham Drive, going from west to east.
I only bothered to look because I thought this one counted for the category at first, but then I found it doesn't. Still an interesting case, though.
When I saw the thread title, the first road I thought of was a short freeway near Dayton, OH, which begins at Exit 32 of I-70 and serves as an access road for the Dayton airport. Right before the airport, the road has an exit for US 40/National Road.
I don't think that freeway has any official name. (Any users from Ohio who might have some info on this?)
