K-1 originally ran north from Comanche through Greensburg, Kinsley, La Crosse, Hays, Stockton, and Philipsburg before reaching K-22, later US 83, near the Nebraska Border. In the fall of 1938, US 183 was extended south, following K-1 between the junction with US 160 south of Comanche and the junction with US 36 at Phillipsburg. By the fall of 1941, the alignments of US 83 and US 183 were switched north of US 36, and all of K-1 north of US 160 was re-designated as US 183.
In 1932, K-1 was gravel between US 160 at Coldwater and US 54 at Greensburg, between US 50S at Kinsley and US 50N at Rozel, and between K-96 at Rush Center, past US 40S at Hays, to Northern Ellis County. By 1938, K-1 had been gravelled in its entirety, and hard-surfaced between Coldwater and Greensburg, between K-4 at Lacrosse and Hays, and between the Ellis/Rooks County line and K-18 at Plainville. By 1941, only the Kinsley-Rozel segment and the segment between the State Line and US 160 remained gravel.
The surviving segment of K-1 was hard-surfaced by 1953.Average Annual Daily Traffic
