How about the opposite, where a Long Ramp is not a separate signed roadway, but does have another On and/or Off Ramp? The Freeway, err, Tollway Ramps from I-88 East to I-294 South and I-294 North to I-88 West (about 1 mile long or so), has an exit to York Rd off the I-88 East to I-294 South ramp
When ISTHA was building the I-355 Extension from I-55 to I-80, they basically told the Suburbs along the route, contribute money for Interchanges, that will benefit your cities and towns and Will County overall, or the 355 Extension would be built with no Interchanges from I-55 to I-80. Who knows if the threat was legit or not, but the Suburbs on the route agreed to contribute Local money to build the interchanges along the route, in exchange for a share of toll revenue for Ramp tolls, I believe. Been a while since I read up on that agreement. Its probably on the ISTHA's website archives
I-175 and I-375 in St. Petersburg FL
Miami's Downtown Distributor (Hwy 970)? The Wikipedia page shows two interim exits, but both appear to originate from the 95, so the road may still qualify.
I-381 in Bristol, VA.
FL 451 near Orlando, but there's a story behind that involving lack of right of way acquisition for future extension of FL 429.
CA 244 (unsigned); this is an extension of the I-80 bypass alignment (I-880 prior to 1982) around the north side of Sacramento. CA 244 was originally planned to extend east through Carmichael and Fair Oaks, crossing the American River and terminating at US 50 near the present Hazel Ave. interchange east of Rancho Cordova; this was deleted from the state's planned freeway/expressway system in the late '70's, along with much of the area's planned freeway network. The facility was originally intended to function as a Sacramento bypass for US 50 traffic. Currently it extends only to Auburn Blvd, about a mile east of the I-80/CA 51 (Biz 80) interchange.
ND I-194
If it extended south along the freeway portion of (unsigned?) ND 810, it'd be golden.
Even TX I-110, MT I-115 and I-315 manage to have exits off them.
Now would you count interstates that cross state lines but have no interchanges, I684 in CT is just passing through, no CT Exits.

NJ76C, ends at NJ 168 and US130, just a connector between the bridge and the two routes.

That actually has a separate exit to 130 before its end point at 168.

I-270Y (signed as I-270 Spur southbound only, northbound just sign as I-270) in Montgomery County.
Also not an Interstate (though it used to be the east end of I-370), unsigned MD-200A, which runs into the Shady Grove Metrorail station from the point where MD-200 and I-370 meet each other, also in Montgomery County.
I-564 in Norfolk, Virginia is less than 3 miles long.
I-695 (Southeast Freeway) in the District of Columbia, links I-395 to I-295 and DC-295.
I-270 Spur in MD North of the Beltway has an intermediate exit between Mainline I-270 and the Beltway, according to Google Maps, at Democracy Blvd
^ None of CP's mentions meet the OP's criteria, however, as all have intermediate interchanges, even MD-200A.

CASR-244 in Sacramento County was mentioned elsewhere.
I-238 (duck) in Alameda County, California is basically just a long connector ramp. The entire CASR-238 (including the part that isn't Interstate or even limited access) extends quite a bit further.

I was going to say I-190 serving as the ORD Airport Access Road, from I-90 and I-294 to the airport terminals, but even it has 3 Intermediate interchanges, with River Rd, Mannheim Rd, and Bessie Coleman Dr, before reaching the ORD terminals
Or the Sam Jones Expressway near IND Airport (former Airport Expressway), but it has 2 intermediate exits between I-70 and I-465 as well (Executive Dr and Lynhurst Dr). And it no longer is the Airport Expressway, since IND Airport built a new terminal that is accessed directly from I-70 just west of I-465, instead of where the Sam Jones Expressway leads

No, I-238 in Alameda County does have entrances and exits besides at its ends.
Hesperian Blvd to eastbound I-238
westbound I-238 to Springlake Dr.
eastbound I-238 RORO to Lewelling Blvd
westbound I-238 RORO to 170th Ave.
eastbound I-238 to Mattox Rd./CA 238
CA 238/Mattox Rd. to westbound I-238
The Ends Spur (I-94) between the Edens Expressway/Skokie Highway and the Tri-State Tollway, north of Chicago, comes pretty close to a long set of ramps from the Edens to the Tri-State, but it has one intermediate half-interchange, with Westbound On/Eastbound Off @ Waukegan Rd/IL-43
Autoroute 930, if you count A-30 and Boul Jean-Leman as one interchange.

I-395 has one exit, to MLK Jr Blvd.
The Crosstown Connector in Tampa. Although one may argue that the Port of Tampa Truck access counts as an exit its actually a separate carriageway running parallel to the two main freeway alignments which has one going from EB I-4 to EB FL 618 and WB 618 to WB I-4, as well as from WB I-4 to WB FL 618 and EB FL 618 to I-4 EB.

The PA extension of the NJ turnpike if you consider the toll plaza as its western terminus. Of course it's either not an interstate or part of I-95, so it's technically ineligible.

The New Jersey Turnpike continues to the state line at about the peak of the Delaware River—Turnpike Toll Bridge (https://en.wikipedia.org/wiki/Delaware_River%E2%80%93Turnpike_Toll_Bridge). Traffic entering from U.S. 130 to head toward Pennsylvania must pay a New Jersey Turnpike toll, in addition to the cashless toll point entering Pennsylvania.
It is officially part of I-95, but will not be signed until PTC (and PennDOT) finish enough of the interchange at Bristol, Pennsylvania (https://www.aaroads.com/forum/index.php?topic=11707.0) (
link to thread here on AARoads) to complete I-95.
Beyond any of the above, the interchange at U.S. 130 (the only interchange on the New Jersey Turnpike without a number, I believe) would presumably make it ineligible anyway.

You are right. I didn't realize there was a toll there as I've never taken that interchange. I've done the reverse, though, and there is no toll at the exit coming from PA, so maybe only the Eastbound extension sort of meets the criteria.

You don't have to tell me. I've briefly acknowledged such in my original post. However, it's currently unsigned, and historically had its own (also unsigned) non-Interstate designation.

The 130 exit is officially 6A, though it's not signed. There is an unnumbered exit south of the "Exit 1" toll plaza to US 40 / NJ 140 / CR 540. Like 6A (at least Eastbound), it's outside the tolled area.
The old Embarcadero Freeway originally signed as I-480 and later CA-480 was viewed as a ramp for Downtown and was intended to connect CA-480 to golden gate bridge.

But there were several exits and entrances on that freeway.
