This intersection is a variation of the version made by Sims firehouse, so all the credits for him. I "replicate" (*) here the Inverted SPUI. I made the cross roads straight and put some pedestrian bridges to join the avenues with footways.
It measures 58 tiles long (highway) and 36 tiles across (avenue).
I've tested this intersection in a heavy traffic area between a commercial and industrial zone, and had a very good performance without bottlenecks.
(*) There is no city-building game that has the tools to replicate in a real way, intersections, roads, highways or any kind of construction nor its behavior. #civilengineer.
