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.
