This is a downloadable schematic of a SPUI (Single Point Urban Interchange). This is, as far as I've seen, the first of its kind on minecraft. The point of a SPU-Interchange is to be compact with as few light-cycles as possible while still allowing for higher traffic-flow than a regular 4-sided interchange. It does this by focusing left-turning traffic around a single point in the middle of the interchange, allowing 2 sides of the interchange to drive at the same time without any conflict. The SPUI has 3 light-cycles, left turns on to the highway (blue lines), left turns of the highway (green lines), and straight forward through the interchange. The right turns are free-flowing so no light is needed there.



This will be used in my future projects. You are free to use this interchange as you please, but kindly change the coulors to make it more unique, and please credit me in the builds where this interchange is used.
