Personal project. Drawing my cues from the original and best metro diagram, H.C. Beck's wonderful London Underground diagram, I have rendered the Interstate system in a much simpler form. The "major" highways (those divisible by 5) are the framework of the map, with the "minor" highways reduced in importance and rendered as thinner gray lines. Even with these highways, a difference in the grays indicates whether they are even-numbered (west-east) or odd-numbered (north-south). Dots on the highways indicate interchanges: large dots where major highways meet other major highways, smaller dots where major meets minor and tiny dots where minor highways begin or end. A full key at the bottom indicates clearly where each highway begins and ends.

Working with Wallblank, an artisan printery in Rockford, Illinois, I sold prints of this poster for over a year with great success. The poster is also featured in the book "Mapping America: Exploring the Continent" (Black Dog Press, 2010), where it is described as " a subversive comment on America's obsession with the automobile and neglect for public transport".
