It was listed as part of a statewide survey that identified historic fragments of the military wagon roads built between 1850 and 1861. The survey found that a road fragment could be considered historic if it was unpaved, that it is "long enough to evoke a sense of destination" where an observer at one end could not see the other end, and that the setting of the road had not been intruded upon with recent buildings or roads.
