Kentucky Route 9007 (KY 9007) is a 2.1-mile-long (3.4 km) four-lane limited-access highway, and was the unsigned designation for the entirety of the former William H. Natcher Parkway. KY 9007 is now the designation of the southernmost section of the former parkway between Interstate 65 (I-65) and U.S. Route 231 (US 231, Scottsville Road), 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.[2] 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 (Scottsville Road) through Bowling Green.
The highway that is now signed as KY 9007 opened in 2011 as a 2.1-mile (3.4 km) extension of the William H. Natcher Parkway, a freeway running from Bowling Green to Owensboro.[4] From 1972 until 2019, KY 9007 was the unsigned designation of the entire length of the parkway. In October 2018, the Kentucky Transportation Cabinet (KYTC) reached an agreement with the Federal Highway Administration to re-designate the parkway as I-165, and signs were posted in March 2019. Because of federal guidelines, the southern end of the parkway between US 231 and I-65 was not eligible for Interstate designation and was instead signed as KY 9007.[5]
