Hi dude, Awesome interchange.
I'd love to test it out as part of my interchange testing series but I've downloaded it and I'm afraid to say it has some big performance problems. I can go through some of them if you want to try and improve it before I give it a proper test.
Firstly, your shortcuts to the immediate right are never going to see much action because traffic in C:S tries to take the shortest route, not in terms of distance, but in terms of number of road segments, so, a lot of traffic is going to try to get on the roundabout and then off straight away at the next exit! I'd have the right turn shortcuts outside the roundabout.
The next big problem and it's one that I made (a lot) is having only a single lane for getting onto the roundabout. The free space on the roundabout tends to come around in clumps and getting multiple vehicles onto the roundabout at a time can really improve traffic flow.
I could go on, but let me know what you think so far.

Stevensdomi build a city around it and let me see!

wow imagine this right in the middle of your huge city

me22ca, it takes up almost an entire tile....

Holy cow that's big -- what is it, 200x200 or something?
