 Paving was not extended south from Arcadia to Bryceland until about 1949, and the section between Chestnut and Lucky was completed by the following year.The last sections of gravel highway on either side of Chestnut were paved around 1952.The remainder of the route between Homer and Junction City made up the northern portion of pre-1955 State Route 115, which was added to the system in 1928.
