K-11 was designated along what is now K-99 in 1927. In 1938, K-11 was renumbered to K-99 to match Oklahoma. In 1940, another K-11 was created from Kiowa to the Oklahoma border as a replacement of a part of K-8, which was truncated because of the extension of US 281 into Kansas. In December 1959, K-11 was cancelled and transferred back to K-8. In 2013, K-14 was realigned to the now defunct K-17, and K-11 took over a section of original K-14 alignment.
