For U.S. - based Scout readers who like to take the scenic route when traveling (as well as anyone curious about American highways), Geotab has compiled this guide to America's Quietest Routes. To identify the quietest highway in all fifty U.S. states, Geotab examined traffic data from the Highway Performance Monitoring System. As visitors enter this site, they can view the quietest highway via a map: for instance, in California, the honor goes to State Route 139 between Susanville, CA up to the Oregon state line. When visitors select a state, they have a chance to take an interactive virtual tour of each highway via a Google Street view. In addition, landscape photographer James Q. Martin has selected his ten favorite highways on the list. Visitors can check out Martin's selections (Alaska's Route 11 tops the list), accompanied by gorgeous photographs.
