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:[1]
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 700 to 799 that do not have portions within the State Primary and State Secondary systems.
Kentucky Route 702 (KY 702) is a 2.855-mile-long (4.595 km) supplemental state highway in southwestern
Elliott County that runs from a point along Neal Howard Creek Road southwest of
Little Sandy to
Kentucky Route 7 at Little Sandy.
Kentucky Route 714 is a 8.733-mile-long (14.054 km) rural secondary highway in southeastern
Shelby County. The highway begins at a four-legged intersection in the village of
Southville.
KY 44 heads south along Mount Eden Road and west along Southville Pike,
KY 53 heads north along Mount Eden Road, and KY 714 heads east along Hempridge Road. KY 714 meets the eastern end of
KY 2866 (Woodlawn Road) and curves north to
Hemp Ridge, where the route crosses a tributary of Guist Creek and an
R.J. Corman Railroad Group line. The highway crosses over
I-64 with no access and meets the eastern end of
KY 1790 (Hooper Station Road) near Hooper before reaching its northern terminus at
US 60 (Frankfort Road) south of
Guist Creek Lake and west of
Clay Village.[1][16][17]
Kentucky Route 718 is a 10.813-mile-long (17.402 km) rural secondary state highway in eastern
Knox County that runs from

Lake Barkley. The highway meets the eastern end of
KY 818 before crossing Glass Creek at its junction with
KY 293 at
Saratoga. KY 730
runs concurrently with KY 293 west to the latter route's terminus at
KY 93. Along the way, the routes have two junctions with KY 818 and a
diamond interchange with
I-24. At the KY 93–KY 293 junction, KY 730 also meets the eastern end of
KY 1055. KY 730 heads north along KY 93 and splits west at the south city limit of
Eddyville. The highway meets the western end of KY 1055 shortly before the highway reaches Lake Barkley, where the highway turns onto Water Street, which passes between the lake and the
Kentucky State Penitentiary, to its terminus at a dead end.[1][28][29]

KY 571 (Seymour–Park Road) at
Park. The highway parallels the Barren–
Metcalfe county line to its terminus at
KY 677 at the Barren–
Hart county line very close to the Barren–Metcalfe–Hart county
tripoint. KY 677 heads north onto Hart County and southeast into Metcalfe County.[1][38][39]
Kentucky Route 742 is a 5.109-mile-long (8.222 km) rural secondary highway in central
McCreary County. The highway begins on Mine 18 Road at the boundary of
