List of Kentucky supplemental roads and rural secondary highways (1–199)
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.
KY 13
Kentucky Route 13 is a rural secondary highway in southern Nicholas County. The highway begins at the Bourbon County line at the South Fork of the Licking River; the route does not extend into Bourbon County. KY 13 heads north along Lower Jackstown Road, which parallels Taylor Creek north to where the route crosses and diverges from the stream at its junction with KY 3316. North of KY 386, the highway crosses and follows McBride Run before continuing north toward Carlisle. KY 13 intersects the Transkentucky Transportation Railroad immediately before its terminus at an acute junction with KY 36 at the west city limit of Carlisle.KY 24
Kentucky Route 24 was a state highway running from US 62 east of Sardis to KY 2 in Carter. By 1976, KY 24 was decommissioned : the section from US 62 to KY 11 was renumbered KY 324, the section from KY 11 to the Fleming County Line was given to the county the section from there to KY 673 became KY 2509, the section from KY 673 to KY 597 became part of KY 597, the section from KY 597 to KY 57 was given to the county, the section from KY 57 to KY 59 was renumbered KY 344, and the section from KY 59 to KY 2 was renumbered KY 474.KY 37
Kentucky Route 37 is a rural secondary highway in southern Boyle County. The highway begins at KY 243 at the confluence of Little South Fork with North Rolling Fork, a tributary of Rolling Fork, west of Forkland. Here, North Rolling Fork forms the Boyle-Casey county line; KY 243 immediately heads south onto Little South Road across North Rolling Fork into the latter county. KY 37 heads east on Forkland Road through the valley of North Rolling Fork. The highway passes through Forkland and crosses Hungry Neck Fork at its junction with KY 1108. KY 37 crosses North Rolling Fork twice west of Johnson Branch, which the route crosses just west of its intersection with KY 1822. The highway crosses North Rolling Fork for the last time as the route veers south and follows Shelby Branch to near the Boyle-Casey county line. KY 37 ascends out of the stream valley and descends along White Oak Road to the valley of White Oak Creek. The highway leaves White Oak Creek at its junction with KY 3365 and heads northeast into Junction City, which the route enters along White Oak Lane. KY 37 runs concurrently west along KY 300 along Shelby Street. At the west city limit, the highway splits from KY 300 onto Stewards Lane, which the route follows to its terminus at US 150 Bypass at the edge of the city of Danville.KY 46
Kentucky Route 46 is a rural secondary highway in southern Nelson County. The highway begins at KY 52 in Nelsonville. KY 46 heads east along Nat Rogers Road to US 31E north of Culvertown. US 31E and KY 46 run concurrently northeast to Balltown, where KY 46 turns south at an oblique intersections onto Balltown Road. That highway heads southeast to its eastern terminus at KY 49 south of Greenbrier.KY 72
Kentucky Route 72 is a rural secondary highway with two segments in Bell and Harlan counties. The western segment extends from Blackmont in eastern Bell to Alva in western Harlan County. KY 72 begins at US 119 at Blackmont. The highway crosses the Cumberland River and CSX's CV Subdivision rail line then parallels a rail spur through the valley of Puckett Creek southeast through Tuggleville and Black Snake. After crossing the Bell-Harlan county line, KY 72 crosses Rocky Branch at Insull and Jackson Mill Creek east of Pathfork, where the route meets the north end of KY 2005. The highway and rail spur terminate at a dead end at Alva at the headwaters of Puckett Creek.The eastern segment of KY 72 runs from south of Bardo north via Harlan to Baxter. Like the western segment, the eastern portion begins at a dead end near a rail spur terminus, this time in the headwaters of Catron Creek. KY 72 parallels the rail spur north through the creek valley through Bardo, Stanfill, and Pansy, where the route meets the west end of the spur KY 1216. The highway continues through Mary Alice and meets the east end of the spur KY 2425 at the south end of Teetersville. KY 72 continues through Elcomb to Catron Creek's confluence with Martin's Fork, the rail spur's confluence with CSX's CV Subdivision, and the route's own confluence with US 421.
KY 72 runs concurrently with US 421 through Dressen before the route splits northeast to parallel US 421 into the city of Harlan. The highway intersects KY 38 and crosses over Clover Fork at the south end of downtown Harlan. KY 72 splits into a one-way pair: northbound follows Main Street and southbound follows Cumberland Avenue. Clover Street and Walnut Street serve to connect the southbound route with the northbound route on Main Street at the north and south ends, respectively. KY 72 follows the right bank of Martin's Fork around a riverbend, in the middle of which the highway meets the south end of KY 3453 and crosses a spillway from Clover Fork. The highway intersects US 421 and crosses Poor Fork at the fork's confluence with Martin's Fork to form the Cumberland River proper. West of Poor Fork, KY 72 reaches its northern terminus at KY 413 at Baxter.
KY 83
Kentucky Route 83 is a supplemental road in southern Graves County. The highway begins at KY 303, opposite the east end of KY 2422, just west of Cuba. KY 83 heads east through the village, where the route has a pair of right-angle curves and veers southeast at its tangent intersection with the south end of KY 1390. The highway veers east again and crosses Bacon Creek west of its intersection with KY 381 north of Lynnville. KY 83 continues east through an S-curve along Leech Creek to its terminus at KY 94 between Lynnfield and Tri City.KY 87
Kentucky Route 87 is a rural secondary highway in western Monroe County, far eastern Allen County, and southern Barren County. It extends from the Tennessee state line near Akersville north to US 31E near Austin. It begins at the Tennessee state line, where the road continues south as unnumbered Akersville Road. The highway heads northeast along County Line Road, which lies atop the Allen–Monroe county line. KY 87 leaves the county line when it veers onto Akersville Road, which heads east and then north through Akersville. The highway crosses the Barren River, meets the west end of KY 678, and crosses Indian Creek. KY 87 enters the city of Fountain Run along Main Street, where the route intersects KY 100 and briefly runs concurrently with KY 2170. The highway leaves the city and enters Barren County as Austin Tracy Road. At Tracy, KY 87 briefly runs concurrently with KY 921, which heads northeast on Thomerson Park Road and southwest on Bewleytown Road, and meets the south end of KY 3179. KY 87 passes through Austin before reaching its northern terminus at US 31E, with the entrance to the Barren River Lake State Resort Park straight ahead.History
From around 1949 until the 1960s, the current KY 87 from Akersville to the Tennessee state line was originally KY 870. That designation has since relocated to a route in north-central Monroe County as KY 87 was extended to the state line in that area, along with its other section near Bugtussle and Gamaliel.KY 87's original northern terminus in southern Barren County was located of Pageville. This was truncated to its current location following the impounding of the Barren River that created Barren River Lake in the early 1960s.
At one time until the 1980s, KY 87 ran concurrent with KY 63/100 east of Gamaliel and made a right turn onto Clementsville Road to end at a locally maintained county road at the Tennessee border, in this case, into Clay County, hence extending KY 87 by an additional. That section was since turned over to the Monroe County Road Department.
Until 2023, KY 87 was a two-segment State highway that was also designated on a roadway from Tennessee State Route 261's eastern terminus at the state line near Bugtussle to KY 63 in Gamaliel. That roadway has received a new designation as KY 382.
