There's one of these in Minneapolis by the airport. It is the most ridiculous thing imaginable. For about a block, you switch over from driving on the right side of the road to the left. I don't see how it saves any time, and it's dangerous as all hell, since you have arbitrarily forced two traffic flows to cross each other in the span of a couple of blocks.

But what do I know? I just have to drive on these streets; I'm not smart enough to design them.

Illinois has one.
Works great.

I forget which city it was, but the main road through it had a traffic light over every one of the eight lanes. During rush hour there might be seven lanes of traffic heading east out of town and only one heading west.

Did you ever try to beat the light and make a left turn against seven lanes of traffic? I did. It’s amazing I lived a long as I have. Oh, I beat the light.

LOL it does take getting used to but for Spfld, MO anything is better for them. All different drivers in that town of 5 universities, retirees, Branson tourists, and country drivers. What a mess. For a small town there were a lot of accidents. Years before I moved there they had never had a traffic study and when they did it made it easier for driving but the locals were still in the habit of going thru the red lights. I learned to look both ways before going on a green light. Boy, do I miss Bass Pro.

"...you have arbitrarily forced two traffic flows to cross each other in the span of a couple of blocks."

I looked carefully at the site and tried to picture myself driving through the intersection with different destinations in mind.

I think I saw the same thing you did.

It removes one hazard by replacing it with another.
The only difference being that the new hazard has a light controlling it.

But I have seen plenty of high volume traditional "cloverleafs" that accomplish the same thing by the use of traffic lights on the ramps.

Having drivers switch sides of the road (to me) is highly counter-intuitive.

They have some of these in Salt Lake City, and they’re not confusing at all. Traffic is well-channelled where lanes cross over and back, and it works very well with no turning across oncoming traffic on any route.

I have a cousin on my dad’s side who is a civil engineer with the NC DOT, we talk a fair amount, he’s my age and almost like a brother. He was talking about these things years ago. They’ve been implemented in NC, I’ve driven through a few of them. I can’t say I thoroughly grasp the benefit as it feels a little convoluted, but apparently it’s less costly and takes up less real estate than a cloverleaf while accomplishing the same goal. That’s my understanding at least.
