The K-12 designation was revived for a new highway between US 66 and the State Border in the southeast corner of the state. Starting out as a dirt road, the highway was quickly improved to hard-surface. By 1950, Missouri had conneceted this roadway into Joplin, and the road was re-designated as an extension of US 166.
