The Dwight D. Eisenhower System of Interstate and Defense Highways of the contiguous United States
Cotton cord
10’ x 19.5’

A scale diagram of the primary interstate highways in the lower 48 states. Each cord corresponds to one interstate, and are tied together at the points on their routes where they intersect. Though the shape of the network is distorted by the free-hanging cords, the distances are preserved, creating an accurate representation, if not an accurate map.
