History
In a September 9, 2009, resolution, K-14 was rerouted along K-61 from Arlington to Hutchinson then along K-96 from Hutchinson to the former end of the K-14/K-96 overlap. K-28 originally overlapped K-14 from K-28's current western terminus north to the southern end of the overlap with US-36, then continued west along US-36. Then on February 8, 1996, K-28 was truncated to K-14 in Jewell. Until 2013, K-14 followed US-54/US-400 west out of Kingman for. From there it went north to K-61 and through Arlington and continued north, then met K-96 south of Sterling. In 2013, K-14 was realigned to the now defunct K-17, and K-11 took over a section of original K-14 alignment from US-54/US-400 north to K-61.
