What Limited-Access Highways have you "Perfect Clinched"?

I'm surprised people think this is so challenging. I suppose it would be if there is a dearth of short 3di's or non-interstate freeways in your state or region, but otherwise there's plenty of scope to do this without necessarily even trying.

I'm reasonably sure I've used every exit/entrance ramp on both I-590 and NY 590, though there's a couple dubious ones that I'll now have to use just to make sure.

I'm pretty sure 590 is the only road I've done it for, and even that I'm not too sure about.  Do I need to re-clinch I-590 south to NY 31 east?  Do I need to get NY 31 west to I-590 south (the left turn version) even though I already have NY 31 east to I-590 south (and does that need a re-clinch?)?  And I'm not 100% sure whether I've been on Ridge Road to NY 590 north or not (and there are some movements at Blossom that I can't recall when I've used them, although I'm pretty sure I have).

Do I need to re-clinch I-590 south to NY 31 east?

Wow, I somehow forgot that used to be a free-flowing entrance onto NY 31. Still, it didn't change enough to require re-clinching IMO.

Interestingly enough, that was one of the two I was uncertain of as well (the other being the original NY 31 WB to I-590 SB loop). Thinking on it further, I would also add I-490 EB to I-590 SB. I have almost certainly used it at some point, but I can't recall a specific instance.
