The Centennial State has two new Scenic and Historic Byways to explore. Called the Scenic Highway of Legends and Silver Thread, the newly designated roads are two of 13 across the state — more than any other in the country — designated by the U.S. Secretary of Transportation as America’s Byways. In total, Colorado has 26 byways, including the ones defined by the state itself. Already a part of Colorado’s Scenic and Historic Byways, these two roads are now part of the National Scenic Byway System.
