The Kentucky Revised Statute 177.020(1) provides that the Department of Highways, a part of the Kentucky Transportation Cabinet, is responsible for the establishment and classification of a State Primary Road System which includes the state primary routes, interstate highways, parkways and toll roads, state secondary routes, rural secondary routes and supplemental roads. These routes are listed below.
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 KY 1 through KY 100. Routes numbered KY 101 and higher are in sequential order as designated by the Department of Highways.
