This scenic byway is located in the northeaster corner of the state. The scenic byway literally makes a rectangular trip around the waters of the South Platte River as they enter Colorado.
This is the shortest of scenic byways in Colorado with a length of only 19 miles. Highlights on this route include the only Pony Express stop in Colorado and Fort Sedgwick (built in 1865). This is also a segment of the Lincoln Highway, the first coast to coast auto route in the United States, and the path of many fifty-niners, heading to the mountains around Denver to seek their fortune.
