A Numeric Topology of the United States Eisenhower Interstate Highway System
A unique map/ diagram that rethinks the Interstate highway system in terms of its numbering protocol (I-5 on the west, I-95 on the east; I-10 on the south, I-90 on the north), and and then rearranges the nation around those numbered routes. A fuller explanation is available here and a larger view is available here.
