who compiled the first list of national roads
Interstate Highway System The Bureau of Public Roads asked the Army to provide a list of roads that it considered necessary for national defense.[10] In 1922, General John J. Pershing, former head of the American Expeditionary Force in Europe during the war, complied by submitting a detailed network of 20,000 miles (32,000 km) of interconnected primary highways—the so-called Pershing Map.[11]
