List of Kentucky supplemental roads and rural secondary highways (3500–6999)


Kentucky supplemental roads and rural secondary highways are the lesser two of the four functional classes of highways constructed and maintained by the Kentucky Transportation Cabinet, the state-level agency that constructs and maintains highways in Kentucky. The agency splits its inventory of state highway mileage into four categories:
  • The State Primary System includes Interstate Highways, Parkways, and other long-distance highways of statewide importance that connect the state's major cities, including much of the courses of Kentucky's U.S. Highways.
  • The State Secondary System includes highways of regional importance that connect the state's smaller urban centers, including those county seats not served by the state primary system.
  • The Rural Secondary System includes highways of local importance, such as farm-to-market roads and urban collectors.
  • Supplemental Roads are the set of highways not in the first three systems, including frontage roads, bypassed portions of other state highways, and rural roads that only serve their immediate area.
The same-numbered highway can comprise sections of road under different categories. This list contains descriptions of Supplemental Roads and highways in the Rural Secondary System numbered higher than 3500 that do not have portions within the State Primary and State Secondary systems. The list includes highways up to the highest signed numbers in the 3600s and also the 6000 series of unsigned routes.

The highway reaches its northern terminus at KY 100, which heads north along Old Gallatin Road and west on Franklin Road. After US 31E's bypass of Scottsville was completed in 1989, the Kentucky Transportation Cabinet established KY 3500 as a supplemental road along old US 31E through a February 17, 1989, official order.

The Kentucky Transportation Cabinet established KY 3520 through a September 6, 2002, official order that also moved US 60 to its new course to the north. KY 3520 took over all of old US 60 except for two pieces at each end that were transferred to county maintenance.
