The district includes an intact segment of the original Fall River Road, along with a variety of historic buildings and structures associated with the road’s construction and maintenance. The segment runs 9.5 miles from Horseshoe Park on the east to Fall River Pass on the west. Initially utilizing convict labor, construction on what was the first highway through Rocky Mountain National Park began in 1913. By September 1920, it was possible to drive from Estes Park to the western terminus of the road at Grand Lake in Grand County.
