Signed into law by President Dwight D. Eisenhower, The Federal-Aid Highway Act of 1956, otherwise known as the National Interstate and Defense Highways Act, ushered in an unprecedented era of roadbuilding in the United States, becoming the largest public works project in the country’s history. Designed to spread freedom and prosperity — and, as the name implies, provide for the national defense — these highways tore through urban neighborhoods, destroying once-thriving communities and displacing countless citizens, many of them people of color. In this special report, we examine just what inspired this massive project and the effects it had on two communities, one in New Orleans and one in Syracuse.
