K-141 (Kansas highway)

K-141 is a 13.47-mile-long (21.68 km) north–south state highway in Ellsworth County in central Kansas. The highway connects K-4 west of Marquette and K-140 northeast of Carneiro with Kanopolis Lake. The entire length of K-141 is a part of the Prairie Trail Scenic Byway, which was designated to highlight the history, culture, and nature of the area. The highway is a two-lane road its entire length.

Before state highways were numbered in Kansas, there were auto trails. The northern terminus follows the former Golden Belt. On August 16, 1955, K-141 was designated as a state highway. Between 1961 and 1963, the alignment was straightened and realigned to cross the Kanopolis Dam. On October 13, 1967, U.S. Route 40 (US-40) was rerouted onto Interstate 70 (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.
