Interchanges, but barely

So I've been doing a lot of driving through northern Lake County, Indiana for my internship, and I couldn't help but notice a parclo "interchange".

https://www.google.com/maps/@41.6101002,-87.4605571,134m/data=!3m1!1e3

US 20 is grade separated from Kennedy Avenue, but the "ramps" look to be the same quality of side streets and have stop signs at each end. They have no medians, or even centerlines, but with no right turn signs, access control is pretty much the same as on a normal interchange of this configuration.

Are there any other examples of this, or is this just a weird Indiana-ism?
This is my signature. There are many like it, but this one is mine.

The usage of RIROs at grade separations to create crappy "interchanges" isn't that common, but it isn't rare either, and it definitely isn't unique to Indiana. Here's a similar setup at the junction of IA 92 and US 59 in southwest Iowa. And here's another one on US 30 in Illinois.

Different but still along the same lines is this primitive interchange built at the junction of the Lincoln Highway (US 30) and the Jefferson Highway (US 65) in the 1930s.

And here's the most compressed cloverleaf interchange I've ever seen, in Peru, Illinois.

Wasn't there one in Kansas, a one quadrant interchange or something like that, that seemed pretty much to be of inexplicable utility?

Also, here's one east of Helena-West Helena, Arkansas.

It's now in the process of getting replaced, but how about the St. Albans exit on I-64 in West Virginia:

[Can't get Ducky to pin AppleMaps to the location exact tonight.  You'll need to scroll northward to see Exit 44.  The new exit topography is shown on the map level, but you can still see the old layout on if you flip to the Satellite view].

US-35 @ OH-32/124. Full size, but who's considered the freeway?
Neither.  They are both four-lane divided highways at this point.  US 35 becomes a three mile freeway starting at the end of the ramp in the northeast quadrant of this interchange.

BTW, this interchange is the only one in the world built this way.

Here is another one from Ohio at the US 40/US 42 interchange northeast of London: https://goo.gl/maps/xgCKxz3zvRdLyT6e9

SR 49 at US 20 is a cloverleaf, but the ramps have additional driveways: https://goo.gl/maps/EJnfwbd5Q2eNisPx9
SR 49 at US 12, I'm not sure if it counts but I think it's similar to others in this thread: https://goo.gl/maps/WJ6J38bvgjFtdz617

The compacted cloverleaf at US6 and IL-251 in Peru also crossed my mind.  So did this compressed cloverleaf using frontage roads along IL-64, at US45:

The eastern end of the US30-US34 concurrency at the eastern end of Montgomery, IL, used to be a wacky pseudo-folded diamond, with a pair of ramps in each of the northeast and southwest quadrants (US34 served as the "freeway").  Thank humanity they converted it into an at-grade intersection.
Avatar is the last interesting highway I clinched.
