Kentucky Route 80 (KY 80) is a 483.55-mile-long (778.20 km) state highway in the southern part of the U.S. state of Kentucky. The route originates on the state's western border at Columbus in Hickman County and stretches across the southern portion of the state, terminating southeast of Elkhorn City on the Virginia state line. It is the longest Kentucky State Highway, though the official distance as listed in route logs is much less due to multiple concurrencies with U.S. Route 68 (US 68) and US 23.

The portion north of Interstate 65 (I-65) was signed as I-165, and the portion south of I-65 as Kentucky Route 9007 on March 6, 2019.

KY 9007 is now the designation of the southernmost section of the former parkway between Interstate 65 (I-65) and U.S. Route 231, which opened in November 2011. KY 9007 was signed on March 6, 2019, when the majority of the Natcher Parkway was redesignated as I-165. KY 9007 functions as a connector, providing a bypass for traffic to utilize to avoid driving into Bowling Green itself by directly connecting I-165 to US 231. It was constructed for this purpose in order to provide some relief to US 231 through Bowling Green.
The original alignment of Kentucky Route 67 (KY 67) was a north–south primary state highway that traversed Edmonson and Warren counties in south central Kentucky. It was one of the original state routes of the state highway system maintained by the Kentucky Transportation Cabinet. It was established in 1929 and was officially decommissioned in 1969. At the time of its removal from the state route system, it was estimated to be 21.491 miles (34.586 km) long as determined by the KYTC's state route logs and county road logs.
The Russellville Bypass is a beltway around Russellville in Logan County in south central Kentucky. The 12.260-mile-long (19.731 km) highway comprises overlapping portions of U.S. Route 68 and Kentucky Route 80, US 79, and US 431. The north side of the circumferential highway was conceived in the 1980s to relieve traffic in downtown Russellville and as part of greater improvements along the US 68 corridor. The first two phases of the ring road, from US 79 on the west side to US 68 on the east side, were constructed in the 1990s. The state decided to complete the orbital road in the 2000s to resolve continuing traffic bottlenecks along US 431 and US 79 on the south side. The second two phases of the beltline were started in 2010 and completed in 2017. Construction of the Russellville Bypass led to a series of route changes over 20 years involving the city's U.S. Highways, special routes, and state-numbered highways.
