Hexagonstructure with roundabout
Use hexagonal structures in your city when grids are just too boring. This cell contains four 2×2 zones, eight 3×3 zones and eight 1×1 zones. To use it place one element and delete its edges where you want to add another element.
Note: a highway should be connected to crossings or edges which on the other hand isn’t connected to the roads to inner roundabouts to avoid traffic problems. I had to use highwayramps to keep the zoneforms how I want them.
