K-34 Kansas highway

K-34 is a 29.26-mile (47.09 km) state highway in southwestern Kansas, running from US-160/US-183 near Ashland to US-400 near Bucklin. It is a two-lane road not part of the National Highway System. Designated on July 1, 1937, it initially ran from the Oklahoma border north through Sitka to US-160. Over time, its route was adjusted, including an extension west along US-160 and a realignment in 1965 that bypassed Comanche County entirely. By 1967, the entire highway was paved.

The highway's annual average daily traffic in 2012 was about 570 vehicles south of Bucklin and 1010 north of Bucklin, with significant truck traffic in both areas. Maintained by the Kansas Department of Transportation (KDOT), K-34 has not been modified since 1993 when its northern terminus was truncated to US-400 near Bucklin.

Originally designated in southeastern Kansas, K-34 was moved to southwestern Kansas in 1937, replacing K-41. Its route has evolved over the decades, with major changes including overlaps with US highways and a final realignment that shortened its length by removing the Oklahoma border concurrency.
