State Route 116 was first added to the state highway system in 1931, consisting of the current alignment but extending farther to the west through Moroni to the forest boundary at Maple Canyon. In 1933, the route was extended further west to the forks of Maple Canyon. In 1969, the route was truncated at its western end, relinquishing the roadway west of Moroni back to local jurisdiction, resulting in the present-day alignment.
