The Kentucky Revised Statute 177.020(1)[1][2] 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.

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 KY 1 through KY 100. Routes numbered 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 that is also numbered as KY 4. KY 4 was previously located elsewhere.

Classifications

The Kentucky Transportation Cabinet divides the highways it maintains into four classifications:[3]

  • The State Primary System includes major routes of statewide significance, including all Interstate Highways and parkways
  • The State Secondary System includes routes of regional significance, which typically connect smaller cities
  • The Rural Secondary System includes routes of sub-regional significance, such as urban streets or farm-to-market roads
  • Supplemental Roads encompasses all state-maintained highways which are not part of the three previous systems, such as frontage or connector roads
