"The Octagon" 8-Way Interchange
The Octagon 8-Way Interchange by Poki_Roo
This 8-Way Highway Interchange features both clockwise and counter-clockwise rings, meaning your cims can choose the shortest route rather than making the whole loop!
I avoided traffic routes that cross each other at grade. The one exception is the innermost ring, because if you’re going to have rings in both directions, there has to be crossover somewhere!
