List of state highways in Kentucky (6000–6999)

This article lists state highways in Kentucky numbered between 6000 and 6999. Kentucky's state highway system is a network of roads maintained by the Kentucky Transportation Cabinet (KYTC). These numbers, although assigned, do not represent signed routes on public roads. Instead, they are internal designations used by the KYTC for administrative and inventory purposes, primarily for maintenance tracking and route identification within their databases and documents. Therefore, the routes listed here are typically not identifiable by route markers or signage in the field.

These internally designated routes can represent a variety of roadway types, including but not limited to: sections of county roads that receive state maintenance, access roads to state facilities, frontage roads along interstates, and short connector segments. Their existence is crucial for the KYTC to manage the expansive road network efficiently.

Information about these internally numbered routes is often difficult to obtain by the general public, as the KYTC primarily uses them for internal communication and record-keeping. Data is primarily found within GIS databases and official KYTC reports.

Because these routes are unsigned and primarily used for internal administrative purposes, they are distinct from Kentucky's primary and secondary state highways, which are marked and used by drivers for navigation.
