U.S. Highway 6 (US 6) is a part of the United States Numbered Highway System that travels from Bishop, California, to Provincetown, Massachusetts. In the U.S. state of Colorado, US 6 is an east–west highway stretching from Utah to Nebraska. Much of the route overlaps other highways in Colorado, and, as a result, much of US 6 is unsigned.
