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.

From faster-than-light travel to journeys through time itself, science fiction makes humanity seem limitless.
