In 1966, following the completion of the last section of I-44 in Missouri, the east end of US 166 was truncated back from Springfield to its current terminus. Most sections of US 166 between Joplin and Springfield were not upgraded to Interstate Highway standards and were renumbered as I-44 Business Loops, state highways (such as Route 174) or turned over to local or county jurisdiction. In a resolution on December 22, 1993, KDOT approved and requested to realign US-166 south of Sedan, and to re-designate the former alignment as US-166 Business. This request was approved by AASHTO in a meeting on April 10, 1994.
