Nemo, you're right, there needs to be more roundabout between each entry/exit

Tried to put it in my city where a lot of traffic was from all sites and this made it even worse as only one car at a time did drive. I may be better if the traffic comes mostly from one side, but then a simple crossing would work too (although it wouldn't look as nice ;) ).

very nice!

it does work, i should make it a little bigger for better traffic flow though

Works like a charm!

Interesting use of highway. Not sure if it works though...
