One of the more ambitious public works projects ever done in the United States was the construction of the Interstate Highway System. Over 35 years from 1956 to 1991, some 47 thousand miles of highway were built with the program at an estimated cost of 477 billion dollars (estimates in 1996 dollars, 2006, and 2009; inflation adjusted). With a market cap of 487 billion dollars, Apple is worth more than the construction of the highways across America.
