I’d expect an “inclo” to look something like this (admittedly pointless, inefficient, unsafe, and ridiculously expensive) design:

EDIT: Just realized my two-minute design sketch had traffic exiting head-on into other traffic.
i wanna see it anyway


Yeah, that'd kill people ...

That's basically a double grade-separated diverging diamond interchange. Traffic isn't exiting head-on into other traffic; it all lines up perfectly. I'm sure China would make one if you sent them the design.

The four inside loops could be replaced with short straight ramps on the outside.

The four U-turn ramps could also be replaced with much longer ramps, and they should — try entering from the south and exiting to the east without getting killed.

Early Mapquest directions on the Coquihalla Highway in BC told me to take a sharp turn off the end of a cloverleaf and onto oncoming traffic.

that kinda ruins the whole "inclo" idea if you take out the cloverleafs

Taking any of the eight outer ramps will put you on a perpendicular road going the wrong direction. Those aren't U-turns.

To clarify, I wasn't seeing that the outside ramps had a connection to the perpendicular highway, I thought they were just U-turn ramps.

Here's my two-minute sketch of what I thought an inclo would look like. Not as good as briantroutman's, but I don't have that kind of editing software. One disadvantage: left exits.

i made an imgur for this

Advantage: no weaving.

Also: the diagonal ramps are superfluous -- the loops take care of those movements. However, outside loops can handle the missing movements, giving you an 8-loop cloverleaf. C/D roads on the outside can mitigate weaving.

A solution with all ramps inside the square is left to the student.

That's because half the movements are missing.  For example, there's no path to go north-to-west.

Well, it requires a lot of carriageway spread, but...

I have a feeling that would take up more space than a regular cloverleaf.

Still less acreage than some of tradephoric’s designs.    :popcorn:

I fixed it- sort of. I didn't have access to my original drawing, so I did this in Paint. My point was to extend the outside ramps as flyovers to the missing movement (example: NB-to-EB diagonal ramp is now a flyover going to WB)
Still no weaving, unless some idiot took a wrong turn.
