Later legislation increased the limitation to 43,000 miles, of which a total of 42,795 miles has been used.Separate legislation allows the Federal Highway Administration to approve additional mileage if it meets full Interstate standards and would be a logical addition or connection.It excluded turnpikes incorporated into the Interstate System within the mileage limitation and the mileage added as a logical addition or connection outside the limitation but financed without Interstate Construction funds.In all, Federal-aid legislation authorized a total of 9 billion to pay the Federal share of the cost of Interstate construction.Congress rejected this plan, but adopted a proposal to finance the Interstate System on a pay-as-you-go basis with revenue from highway user taxes.

Through the remainder of his years as President, he searched for ways to solve the problems that plagued the program in its early years and pushed for continued work on the Interstate System.His leadership in promoting the and moving the program forward on schedule has earned President Eisenhower the title "Father of the Interstate System."
