Interchange Choreography is a collection of complex interchanges of three or more roads. Hundreds of interchanges have been constructed with only two roads that are just as complex or more so than those with three or more. However, colors look more interesting with three or more roads so only those were included. Each line in a diagram was colored and refined manually without the use of code or other automation. Satellite photos of these and many more interchanges are available in the earlier Road Knots project.
