Interstate Highway System in form of Subway Map
Although I believe in Charles Kuralt’s words that “thanks to the Interstate Highway System, it is now possible to travel from coast to coast without seeing anything”, the highway system in the U.S. is pretty darn efficient and is primarily responsible for keeping costs low for consumers. It may be the single-best investment by the government although it had several sociological impacts on the form of the city. The beauty of the interstate system is that it is simple as envisioned by Sensex Prime in the style of H.C. Beck’s London Underground Diagram (via Kottke). It however doesn’t include the ring roads around each major city that are numbered in a three-digit code with the last two-digits marking the highway it splits. Did you also know that odd-numbered interstate highways go north-south and even-numbered go east-west? There is order in what may seem like chaos.
