other examples like this diagonal interchange?

Reminded by the other "diagonal" thread, I saw this one on a Google vacation and wondered if it's common.  I can't think of other examples ... weird combination of three-level and split diamond:

Recognized it instantly from the layout without reading the map labels. My understanding is that was built because those two streets crossed at grade at that spot before I-35 was built, and they wanted to make sure to keep them both continuous for whatever reason. Either way, it's one of the first interchanges you come across when you enter metro KC from the south, and it really makes you feel like you're entering a big city!

Before they built the three-level interchange, US 169/K-7 was the only road that crossed over I-35.  151st Street curved and met US 169 at T-intersections on both sides of I-35.

Not for automobiles, but The Richmond, Virginia Triple Railroad Crossing.

It's complicated...

I immediately thought, Oh! that's just like the interchange on I-35 at... oh, wait, that's the one you posted.

That's very interesting. Never seen one like that before.

I'm not sure whether the redundant turns help or hinder the design, to be honest.  You could remove signal phases if you removed some of the left turns, but then people would have to travel farther to make some of the turns.

Next to a demoed dead mall, too, I see.

I-390 exit 11 comes to mind, although the intersection between the 2 surface roads is at-grade and offset from I-390.

Pretty good example, though.

Speaking of the Rochester area, how about this?
It's a completely different (and much more complicated) type of interchange, but definitely similar visually.

And it's also unique in the sense that you can be waiting at a stoplight while on both an overpass and underpass.

Unless I'm missing something, I don't see any ramps that serve two different crossroads there.

That's why I mentioned it being a completely different interchange type, but similar visually.

There is this parallel road that starts as a ramp, ends as a ramp, and has at-grade junctions with both Highland Ave and NY 96. I guess that's similar to what the OP is looking for... but with a twist... the ramp ends up on a different highway than it started on!

Half-diamonds where a diagonal freeway crosses two perpendicular surface roads are pretty common, but they don't always connect like that.  Here are a couple of local examples:

Also, since we've been discussing the I-35/US 169/K-7/151st Street interchange in Olathe, KS, it's worth pointing out that the newer interchange just over a mile southwest was handled in a bit more conventional manner: https://goo.gl/maps/nVxhQPuJf6xyvZ9Y9
