They are the best system of controlling and alleviating traffic in an urban area. Cities should have those types of intersections in their urban core near convention centers, ball stadiums, multi-purpose facilities.
I hate a bottleneck after a big event like a concert, and I think under and over passes make sense. Your thoughts!
Yes, it would help with traffic, but those types of intersections would be hard to but into dense urban areas and also significantly affect walkability.
There are other places with under and overpasses. In Chicago there used to be one by a major amusement park. One in Lake County IL recently completed. But they mostly make sense where traffic is always heavy. Near a football stadium where it's only congested ten games a year? Hardly worth the effort. Sometimes there is incidental grade separation where a bridge over a river or railroad also goes over a road. Of course, civil engineers do reams of traffic studies before one is built.
There are some cities that use them effectively, and the residents are very grateful for the light traffic. It works in practice every bit as well as it works in theory. I've been living in one of those paradises for the last year.
The reason you don't do these things is because making a great city and moving the most amount of traffic as quickly as possible are not the same thing.

A lot of things make little sense really. Such as having major interstates build going thru major urban high density areas with the materials they carry.
