My understanding is that a significant part of the motivation for the interstate system was military, which doesn't seem to get any consideration in this article. Wikipedia says: "The Interstate Highway System gained a champion in President Dwight D. Eisenhower, who was influenced by his experiences as a young Army officer crossing the country in the 1919 Army Convoy on the Lincoln Highway, the first road across America. Eisenhower gained an appreciation of the Reichsautobahn system, the first "national" implementation of modern Germany's Autobahn network, as a necessary component of a national defense system while he was serving as Supreme Commander of the Allied forces in Europe during World War II. He recognized that the proposed system would also provide key ground transport routes for military supplies and troop deployments in case of an emergency or foreign invasion." https://en.wikipedia.org/wiki/Interstate_Highway_System https://en.wikipedia.org/wiki/Interstate_Highway_System
