65 years ago today, President Eisenhower signed the National Interstate and Defense Highways Act, creating a system of continuous highways that crossed the U.S. #Interstate Eisenhower, had travelled across the U.S. as part of the @USArmy's 1919 Transcontinental Motor Convoy. During this trip, Eisenhower witnessed the dismal conditions of roads and their lack of connectivity. The trip from Washington D.C. to San Francisco took 62 days.
