A representation of America’s Interstate highway network using the familiar symbology of a subway or transit map – coloured route lines, 45-degree angled lines, interchange “stations” and distorted/simplified geography. The map focuses more on connections than city size or “importance” – thus a small city at the junction of two major routes (those divisible by 5) may seem to be more important than a larger city at the junction of minor (grey) routes.
