This eight-way intersection in Detroit: https://goo.gl/maps/hgdQ7zQGKc22 (Tireman is the only road remotely resembling a major road, and one of the legs was cut off at one point, but the curb markings are still there)

A six-way intersection not far from the eight-way one: https://goo.gl/maps/pU1xV2rFDxN2 (Both Joy and Wyoming are major streets, and the NE-SW street (Esper St) ALSO runs NE-SW through the aforementioned eight-way intersection)

Lol I lived not too far from there for awhile on Steel just south of Chicago I never could understand the concept there. Meyers that doesn't actually intersect all those streets is fairly busy and Miller is fairly busy going all the way to Fort. Tireman is probably the busiest of those streets since it runs halfway between Warren and Joy Road.

I take pictures of road signs, that's about it.

General rule of thumb: Just stay in the "Traffic Control" section of the forum and you'll be fine.

This intersection isn't really insane, it's just weird.
That one is pretty strange. I don't think I've ever seen a state highway end at an exit ramp off an Interstate highway before this one.

Yeah me neither. I haven't found anything else like that on Google Maps.

I've been all over and can't think of a single one, that makes this one insane.

This used to be a six-way intersection in west Atlanta, since reduced to five-way:

Marietta Blvd is old US 41 back before Cobb Parkway was built.

Hate speech is a nonsense concept; the truth is hate speech to those that hate the truth.

People who use their free speech to try to silence others' free speech are dangerous fools.

RI 246.
Clinched, minus I-93 (I'm missing a few miles and my file is incorrect)

Traveled, plus US 13, 44, and 50, and several state routes

I will be in Burlington VT for the eclipse.

Two things.  First, the "loop" on the ramp has the arrow in the wrong direction.  Second, don't trust everything you see on Google Maps**.

** - In this specific case, "297" is a county road, not a state highway.

Woodlands Pkwy seems like it is trying but failing at expressway status.

I must be missing something. That just looks like a standard diamond interchange with a RIRO on one ramp.

I certainly don't see RIROs on slip ramps very often, but they're far from rare, and certainly wouldn't quality as "insane". Not in my opinion, at least.

Thanks for sharing.  You'll see that "splitting" of opposite directions where frontage roads and ramps intersect.  The idea is to prevent people from turning the wrong way down a ramp (and have a high speed head-on crash).  Here's a drawing from TxDOT (see the bottom intersection):

I am pretty sure that CASR-244 ends at an exit ramp from I-80 near Sacramento, but this might be a "temporary" (as in "not the way the engineers planned it, but has been that way for 30 years and we know of no current plans to change it") situation. My memory is fuzzy, but CASR-90 may do this also.

In this part of the world I nominate this intersection. The stop sign says it all.
Supporter of the construction of several running gags, including I-366 with a speed limit of 85 mph (137 km/h) and the Hypotenuse.

Please note that I may mention "invalid" FM channels, i.e. ending in an even number or down to 87.5. These are valid in Europe.

Nothing's more confusing than a three-way intersection with a 'proceed', stop, and yield for each of the approaches. I would have no idea what to do there. My gut says the yield sign has 2nd priority, with the stop sign third in line.

Since No one has shut me down, OR 18/OR 99W in Dundee OR.

Ehh, there's something similar on US 1 south of the Quantico Marine Base. If you want insane, try New York State Route 112 at Roosevelt Avenue, State Street and Scranton Road, all converging on the old Port Jefferson-Patchogue Highway in Port Jefferson Station.
I didn't know there was another one that existed that was like that. That's the first and only one I was aware of.

Similar intersection in Nogales, Arizona at 82 and Grand Ave:

https://goo.gl/maps/UrVChhSeo782

Due to terrain and adjacent railroad.

Here's another, also to clear a parallel railroad (Butler, IN, US-6 at CR 61).
