The Mount Evans Scenic Byway consists of State Highway 103 from Idaho Springs, Colorado on I-70 about to Echo Lake, and Colorado 5 from Echo Lake , ending at a parking area and turnaround just below the summit. The latter has long been the highest paved road in North America (5th highest in the world) and is only open in the summer. Colorado 103 continues east from Echo Lake to Squaw Pass, from which it connects, via Clear Creek County Road 103 and Jefferson County Road 66, to Bergen Park from which Colorado 74 leads to Evergreen Colorado.
