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 roadway links Interstate 275 (I-275) to the Cincinnati/Northern Kentucky International Airport, and has been designated as a connector route by the Federal Highway Administration (FHWA). A road first appeared near the location of KY 212 around 1937. A short road was built in the location of KY 212 when the U.S. Army Air Corps built the predecessor to the CVG Airport. The road was reconstructed to a divided highway in 1972, but was part of KY 1334 until 1974 or later, when KY 212 was designated, and KY 1334 was rerouted via Loomis Road and Whitson Drive to end at KY 20.

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 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.
Kentucky Route 3145 is a rural-secondary state highway located entirely in Warren County in South Central Kentucky. The route serves as a connector between U.S. Route 31W and Interstate 65 (I-65) on the far east side of Bowling Green.
