just... do a roundabout, man

Is that monstrosity over 10 lanes wide? I think it's closer to 18 in actual width. That could be as wide as 63 meters (206 ft). Insanity.
Anything but building some trains and putting buildings closer together.. We'd sacrifice anything and everything on the altar of cars.to appease the rich and the selfish.
Apparently this is actually less wide compared to his original concept that served 19,000 vehicles per hour.

21 lanes wide, however there are medians making it wider than that.
A few things stand out from the demo/concept:
- Proposes to knock over a lot of buildings to grow the intersection footprint by... I'm guessing 3x.
- Avoids constructing an overpass while aping features of a diverging diamond and NJ-style jug-handles. I think this is possibly cheaper, but probably not by a lot.
- Lots of runway for merge zones, far from intersection.
- The "just one more lane" gang is gonna be disappointed with the inevitable bill to widen this monstrosity in ten years.
- Makes it impossible to turn into local parking lots which might be inducing demand for the intersection in the first place.
So, it's not great nor abysmal but man is that a fuckload of extra pavement just to build a pedestrian "dead zone". With respect to the last point, I've seen that kind of thing happen first hand. By the time the project is over, local business astride the new overpass/intersection have already closed their doors since traffic is now optimized to blow past everything at 55MPH.
IMO, if exercising imminent domain is on the table, may as well beef up and/or add secondary relief roads around this intersection instead. Spread the infrastructure build and cost into multiple smaller projects and leave the existing intersection to through and left-turn traffic only. The result should be calmer and less accident prone. Then, make sure that pedestrians and bikes can get around these multiple smaller roads.

It isn't. This concept was not ultimately chosen for this intersection. In fact the inventor of this concept was a pretty... interesting guy.

It's the state level version of endless wars to funnel money to donors. The fact that they will never be done is the point.
That looks like some truly dumbass nonsense
It honestly is quite amazing from an engineering standpoint but would be pretty immoral to build in real life
I disagree, it looks like quite bad engineering to me
How so? It's a total traffic killer, in more ways than one :P
Isn't engineering supposed to involve efficient use of resources? Space, time, cost, maintenance; this looks like an awful design for transporting things.
This is more like art; wasting resources on something grandiose that makes some sort of 'statement', whilst honouring daft constraints like 'each twat must be at least 4m from every other twat at all times'.
That's exactly where this belongs—it's textbook city builder meme material.
Reducing commute time by two (2) minutes and it will cost 30 billion dollars. Seems like a good value proposition.
I guarantee you that people will miss the exit ramp and fuck the whole thing up when they try to make a sharp turn in the middle
Ok so obviously it's hideous, costly, wasteful etc, but also, sooo many people would pull into wrong way traffic just trying to get through it
