India’s most holy river is called “Mother Ganga.” America’s most holy highway is called “The Mother Road.” Route 66 is the highway equivalent of Old Glory and the American equivalent of the Silk Road. Between 1926 and 1985, it linked Chicago and Santa Monica for vacationers and every kind of itinerant during a period of westward migration. It’s been a symbol of American freedom and hope in some of our best literature, like Jack Kerouac’s On the Road and John Steinbeck’s Grapes of Wrath.
