Was wondering if it were possible to make an opposite of this? Where the lanes are on the opposite side?

Ughs, how to explain it. If you rotate it, the lanes are the same regardless of the rotation, what I am referring it to flipping where the lanes are so hat you can easily draw the road from one inside cloverleaf to another without needing to make adjustments to the road (such as curving it upward to meet the upper part of the road, when drawing from the lower road)

Could very easily be transformed into a Swastika, for the more, ahem, aryan Führers Mayors.

I think so too :)

This one looks even more like a svastika :D (or is it a bad thing ? o.O )
