A man-made wonder, a connective network, an economic force, a bringer of blight and sprawl and the possibility of escape--the U.S. interstate system changed the face of our country. The Big Roads charts the creation of these essential American highways. From the turn-of-the-century car racing entrepreneur who spurred the citizen-led "Good Roads" movement, to the handful of driven engineers who conceived of the interstates and how they would work--years before President Eisenhower knew the plans existed--to the protests that erupted across the nation when highways reached the cities and found people unwilling to be uprooted in the name of progress, Swift follows a winding, fascinating route through twentieth-century American life. How did we get from dirt tracks to expressways, from main streets to off-ramps, from mud to concrete and steel, in less than a century? Through decades of politics, activism, and marvels of engineering, we recognize in our highways the wanderlust, grand scale, and conflicting notions of citizenship and progress that define America.
