So I don't have any of these and I doubt you guys have many, but how many roads have you gotten a perfect clinch on?
My rules:
Clinch both directions
Go on every exit ramp, both ways, both on and off the road
Visit every rest area, if applicable
Now I doubt many have done this, but if you have I'm curious to hear, and if you are close on a road that would be cool as well.
Edit: yes I mean, freeways
The easiest ones would be urban 3di. For example, I'm close to having I-235 in Wichita, but I'm sure I'm missing a couple of ramps here and there.
Another easy one in this area (which I don't have) would be I-335.

Some of us use the term "certified" for highways traveled in both directions. I don't track that.
Your criteria don't seem to allow for "perfect clinches" of non-freeways. Would you allow for exits to and reentries from all at-grade intersections?
The candidate from my own recent travels that comes to mind is Northwest Territories route 9. I traveled the entire 97-km highway in both directions, stopped at both rest areas, and left and returned to the highway at both of the major at-grade intersections (there are some private driveways, and side roads such as to gravel pits, which I didn't bother with due to time constraints and also wanting not to piss anybody off). The most "imperfect" feature of the road is that it's completely unpaved, as is common in the Arctic.
Since you didn't specify that this has to be "numbered highways" I could give you hundreds of answers...

I was thinking more of freeway standard roads, or roads with off-on ramps.

Alright you guys, if you are just gonna be silly and not answer the question, that's fine. I'm just letting you know that you are being silly.
I think you lost the room when you weren't specific. "Highways" is a pretty broad term and yet you claimed past the original post that you wanted freeways.
Closest one for me is I-865. Missing the I-865 EB to I-465 SB ramp.

Yeah I was using Northeast terms for some reason. I changed it to limited-access roads.
There are plenty of freeways I've clinched in both directions, but I don't think there are any on which I've even used every interchange, let alone every ramp. Not even some super short ones like CA-259 in San Bernardino, or I-115 in Butte MT, or I-238 in San Leandro CA. I've used every interchange on I-180 in Cheyenne (one), but only two of the four ramps, and I wouldn't count that joke road anyway. When I drive I-405 in the San Fernando Valley, which I've done at least a thousand times, I can still identify a couple streets I've never gotton off or on at. It's just not how I use roads.
Off the top of my head:
I-565
Memorial Parkway, Huntsville (until the new overpass at Mastin Lake is opened, anyways)
I think that's literally it, lmao.
Doing this on purpose seems tedious, so the only way it would happen is if I did it on accident while doing something else. I don't really track which exits I use, though, so if I have done it I'd probably never know.
CC-215 was originally built by having the road divide at the site of each future interchange and use the future ramps (i.e. CC-215 intersected with the surface road where the ramps do now, then returned to the current mainline). If you had certified it then, would that count?
WA 520 might be the only true one for me, and that's thanks to using buses (which use bus-only ramps).
If we count limited-access sections of highways that also have other types of roadways, then I can also include WA 522, WA 525, WA 526, and WA 529.
Very close on I-705 and a few other highways as well.
With a few exceptions, good luck taking an exit ramp both ways without being pulled over or arrested.
The most likely non-trivial example that probably fits here for me is I-890. I know I've gotten on and off each exit, but less sure I've done so in all directions to use all ramps.
For a trivial example, anyone who's traveled I-587 in Kingston in both directions has done this. Unless you have to take all ramps from the Thruway entrance roundabout and all directions at the traffic light at the other end.
I am fairly certain I have done this for I-355, but I could be missing a ramp or two. Only exception would be if I have to have used every toll booth lane also. I lived along it for much of my early life, commuted on it, driven around for work and play, and am fairly certain I have taken every exit/entrance in every direction
I-865 is a certain yes
Had I lived longer in Peoria than a few months I'd have IL 6 and I-474 on my list. I think I might have IL 6 anyway - close at least
This is something so tedious that I wouldn't think about purposely trying to accomplish. But when living (and driving) in an area now for 40+ years, you're bound to make some progress on that just from the sheer number of drives on that highway.
That said, I do have a "Perfect Clinch" of I-97. I know, I know, it's not that long.
Some of the shorter 3di highways could easily be "perfectly clinched" due to their shortness. I wouldn't be surprised if I were near 90% for I-695 (Baltimore) and I-495 (Washington).
CA 77 since RGT clarified this to "limited access."
I believe I've done this with WIS 30, though that's a three-mile highway with a whopping five exits (one of which is only in one direction) that I live near and therefore take a lot. Even then, I'm pretty sure I've only used one of the ramps because of a construction detour.

Does it count, if you have taken all of the exits in both directions only in the controlled access portion?
With or without that requirement, I've "perfect clinched" CASR-244, -237 and -262 as well as I-238. I'm really close on I-880 and I-980 in California. I'm also very close on CASR-17 and -238 (especially the freeway portions). In every cases, I've taken every exit, but I'm unsure that I've done so in both directions.
If taking only the freeway exits are all that is required, you can certainly add US-395 to my list.
Hmm. Using these criteria I actually have a few:
Interstate 310,510, and 610 in Louisiana
Interstate 12 in Louisiana
Interstate 610 in Texas
Hardy Toll Road, westpark tollway, Sam Houston tollway all in Houston Texas.
I believe I had accomplished it with I-480 in Omaha and Council Bluffs until they reconstructed the I-29/I-480 interchange, which didn't happen until after I moved from the Omaha area.
I recall that
@triplemultiplex said he's accomplished this for work purposes for entire states. And not just 3dis...
For me: I-595, but not since they added all the tolled express lanes. I've taken the express lanes all the way through from I-75 to I-95 as well, but definitely not from every possible access point. I also don't think I've taken every possible "Texas U-turn" movement, either...not sure if that's part of the criteria. However, every possible two-or-four ramp configuration and all the stacks for the "free" lanes? Yes.
Maybe I-195 and I-395 in Miami. There's not much to them.
I am missing one or two ramps of I-565 in the Huntsville area, towards the eastern end. Maybe one day if I'm bored.
I don't aim for this kind of thing when traveling, unless the ramp/bridge/flyover is particularly interesting.
