History K-140's route was established in 1925 as US-40S. By 1936, the route had become the primary route of US-40, with the old US-40N becoming US-24. 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 brief 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. The routing of K-140 has remained unchanged since. The K-140 route has been a paved road since at least 1932.
