How The Interstate Highway System Changed Business

"On June 29, 1956, ... President Dwight D. Eisenhower... signed the bill for a $25 billion National System of Interstate and Defense Highways... But in the process of laying 42,793 miles of limited-access pavement, the Interstate builders changed America in ways few could have imagined in 1939 or even 1956... The Interstate system was sold as a savior for both rural America and declining urban cores; instead it speeded the trend toward suburbanization at the expense of both city and country... For American businesses, the Interstates literally and figuratively transformed the landscape in which they operated."
