What do Bonnie & Clyde, Jesse James, Nancy Drew and Jack Kerouac have in common? U.S. Route 6 in Iowa takes two-lane motorists from Davenport on the Mississippi to Council Bluffs on the Missouri. Built in one day by 10,000 farmers and businesses across the state, Iowa’s Route 6 is part of the second longest transcontinental highway in America. River to River: Iowa’s Forgotten Highway 6 guides viewers on a nostalgic classic car journey through yesterday’s soda shops, filling stations, general stores, drive-ins, and roadside attractions. Experience the sights and sounds, the people and the places that the four-lanes have forgotten...before they are gone forever.
