On June 29, 1956, President Dwight D. Eisenhower signed the Federal Aid Highway Act of 1956, authorizing the construction of the Interstate Highway System. The New York-to-San Francisco transcontinental route in the system, Interstate 80, would however largely follow a different path across the country than US 30. I-80 would also not be signed all the way to the New York City, instead terminating in Teaneck, New Jersey, west of the Hudson River just a few miles short of the George Washington Bridge.
