Between August 1985 and February 1990, KY 402 was a designation of the Bert T. Combs Mountain Parkway in northeastern Kentucky, which is now designated in one section as KY 9000 and in another section as KY 9009. Until November 1982, KY 402 was a designation of the road from Flemingsburg to Beechburg; this is now part of KY 3301.
From 1954 until July 18, 2002, the current alignment of KY 402 was originally signed as a part of KY 80; KY 80 was rerouted onto its current designation onto a new four-lane alignment through Calloway County; the old KY 80 alignment was redesignated as KY 402 during the 2002-2003 fiscal year.[2] [3] From 1929 until 1954, this highway was signed as KY 98.[4]
