	On October 6, 1954 the Kansas State Highway Commission, now known as Kansas Department of Transportation, passed a resolution to make Kanopolis Lake Road a state highway as soon as Ellsworth County had brought it up to state highway standards. Then in an August 16, 1955 resolution it was designated K-141 as the county had finished required projects. On October 13, 1967 US-40 was rerouted to overlap the newly constructed section of I-70 from Dorrance to Salina. At that time K-141 was extended from its northern terminus eastward along old US-40 to Salina. This extension was breif because on November 27, 1968 old US-40 from Ellsworth eastward to Salina was designated K-140 and K-141 was truncated to end at the new K-140, its original northern terminus.
