The best-selling author of Route 66 and a Pulitzer Prize–winning photographer celebrate America’s first transcontinental highway in all its neon glory. It began in 1913 with a glorious new highway that connected the bright lights of Broadway with the foggy shores of San Francisco. It was a magnificent and meandering road that enticed millions of newly motoring Americans to hop in their Model Ts and explore the fading frontier. It was the road of Gettysburg, Pretty Boy Floyd, Notre Dame, the Great Salt Lake, and the Gold Rush Trail. Once a symbol of limitless potential, it has undergone a miraculous revival. With hundreds of rare photographs, this ode to a bygone era guides us across the true spine of the country, exploring vintage diners, Art Deco buildings, and funky roadside attractions—all waiting to be discovered.
