By the end of the century there was an immense network of paved roads ,residential streets,expressways,and freeways built to support millions of vehicles,The high way system was officially renamed for Eisenhower to honor his vison and leadership.The year construction began he said:"Together,the united forces of our communication and transportation systems are dynamic elements in the very name we bear -United States.Without them ,we would be a mere alliance of many sepaeate parts."
