Minnesota Single Point Urban Interchange(SPUI)
This is a Single Point Urban Interchange. It has a very high traffic capacity.
Based on a real life design near Minneapolis, Minnesota, USA, it is situated near the city of Rosevile. it provides a really effective entrance/exit to and from the highway.

If you would like to increase the capacity even more, you could upgrade the highway ramps with 2 or 3-lane highway if you have the Network Extensions Project.
If you have any recommendations feel free to post them down.
If you want a particular type of interchange, you can post an order to me in the comments.
