Freeways that only use or are missing a certain interchange type

[thspfc]

There are only two traditional cloverleaves (cloverleafs?) in Wisconsin - I-39/90/94 and US-151 in Madison, and I-43 and WI-23 in Sheboygan. Do any states have less?

Unless I'm missing something, Alaska has zero cloverleaf interchanges.  Fairbanks comes really close with a six-ramp ParClo, but I can't locate the real deal anywhere in the state.

Ha, I should've thought of Alaska. Maybe Hawaii has fewer as well.

That might be correct.  I-H1 Exit 24B comes close, but no cigar.

Isn't there also one at I-43 and US-12 in Elkhorn? Unless you don't count the C/D lanes on US-12 as being "traditional".

I-5 in California doesn't have any traditional SPUIs, though there are a couple of offset SPUIs in Anaheim.

The Sheboygan interchange has C/D lanes on I-43 while the Madison interchange also has C/D lanes and another half-diamond using the same C/D lanes on the interstate triplex, so I don't think it's a problem. The I-39/90 and I-43/WI 81 interchange was a traditional cloverleaf, but I believe it's in the middle of being reconstructed with a new design. It looks really strange, but US 53 and WI 29 near Chip Falls qualifies. I-94 and US 53 in Eau Claire also is if you don't mind a stop sign at the end of a ramp.  I believe the I-90 and US 53 interchange in La Crosse used to be one, but it's been 35 years since I was in LaCrosse and I was really drunk that weekend so my memory may be faulty.
