America 13: Highways

Arterial highways exist everywhere, but interstates are a whole circulatory system. They don't just run between cities, but through them, above them and under them, threading their way through every part of American life. The vehicles pulse down the streets and avenues, suffusing the city's centre with people, but also the outlying organs, the factories, the suburbs, small towns, rest stops, roadside attractions. And when an interstate blocks up, when you can see nothing but cars clotted together for miles in either direction... there's nothing else for it, it feels like death.
