Between Idaho Springs and Golden is one of the most scenic stretches of Route 6.  This 1950s Standard Oil highway map of Denver shows how both U. S. Routes 6 and 40 connected Idaho Springs with Denver. In spite of I-70's intrusion into the scene, Route 6 today still follows the same path along Clear Creek from Idaho Springs to Golden, then into Denver on what would become the 6th Avenue Freeway.
