Like Motel 6 and muddy cups of coffee, rest stops have become shorthand for the American open road in all its languorous, dust-strewn glory. In 2007, the Austin, Tex.-based photographer Ryann Ford was driving along the famed Route 66, when she began taking photographs of the humble structures, many of which date back to the 1950s and "60s. "I wanted to document them and create an archive," Ford says of the more than 100 stops she has shot across 11 states. But I also wanted the photos to be beautiful and really emphasize how different they all are. Her resulting collection of images - which includes tepees along the Rio Grande and a solitary picnic table in the white-sanded desert of New Mexico - captures a disappearing vestige of midcentury American design.
