I added your junction design, but optimised it a bit for one way, and unsharpend some edges.
This savegame is about templates and basics.
There are some negativ examples. obviously

But the people should learn, what are the pro's and con's of each junction.

So they need a base to undersand and to differ.

Couse of that I added also "The Isle of Statements", where this is remarked.
You can take some inspiration for your next junction/hubs.
I also included a list of users who added junctions.
