== History ==

[[Kentucky]] began a numbered route system in the 1920s.  Originally numbered so that odd numbers ran from north to south, increasing to the west and even numbers ran east to west, increasing to the south, this pattern was only followed for [[Kentucky Route 1|KY 1]] through [[Kentucky Route 100|KY 100]].  Routes numbered [[Kentucky Route 101|KY 101]] and higher are in sequential order as designated by the Department of Highways.

An exception to the pattern for highways numbered 1 through 100 is [[New Circle Road]], a circular bypass around [[Lexington, Kentucky|Lexington]] that is also numbered as KY 4. KY 4 was previously located elsewhere.
