This transportation corridor is approximately 10 miles in length, varies in width from 14 to 30 feet, and is comprised of the public roadway and right-of-way including lookouts, culverts, retaining walls, and curbs. It affords a winding and narrow drive with scenic views of Honolulu, Diamond Head, and the Wai‘anae Range. The Tantalus–Round Top Road rural scenic corridor is significant for its association with the social, cultural, and recreational history of Honolulu and the Tantalus–Round Top Drive area. It is also significant as a transportation route that demonstrates engineering designs and road construction techniques adapted to a rugged topography in Hawaii and which were typical of the historical period of construction.
