Hexa Pinavia, the Snowflake

Do you hate that intersections on the workshop always have only four branches? Does that limit your creativity? How would you like a junction for six instead? And supporting six lane highways, to boot?

The Hexa Pinavia is the most ambitious interchange to be attempted yet. Part polygon, full insanity, it has THIRTY SIX lanes that never intersect. All traffic will pass through without encountering any other cars. They are all one lane highways with the maximum 100 km/h speed limit, too, so it's not just ramps. These are Tiny (tm) ramps, squeezed into the tightest possible configuration.

The interchange only has two levels, at 0m (ground) and -5m (sunken), so it's not vertically space challenging in any way like a Stack Interchange. It can fully handle interchange to all six directions, INCLUDING U Turns.

The Hexa Pinavia is enormous, so make sure you have sufficient space. In fact, you'll have to merge the outgoing lanes yourself...
