It is Huge. It is probably unneccessary, but it works wonders on that spagetti intersection problem we all get at times. Did you need a Ton of Exits for all that freight? Well here you go.
You must add exits to the top ring, otherwise the structure is just an efficient 2 way intersection. But its design allows you to customise its exits in any way you like.
Please let me know what you think of it.
