Happy Birthday Interstate

President Eisenhower signed the law establishing the Interstate Highway System on June 29, 1956. It spurred a gigantic building boom and connected cities like never before, shortening cargo transits and expanding family road trips. It caused a major overhaul of the trucking industry, put new pressure on rail and air service, but was a huge boon to commerce in general. It stands as one of the greatest public works projects in history, anywhere.
