The Julian M. Carroll Purchase Parkway is a controlled-access highway in the US state of Kentucky running from Fulton to Mayfield, near Kentucky Dam, for a length of . It begins at the Tennessee state line concurrent with U.S. Route 51 (US 51) only a few yards from an intersection with US 45W, US 45E, and US 45 at its southern terminus, and at I-69 just north of US 45 at its northern terminus. It is one of seven highways that are part of the Kentucky Parkway System. The parkway previously extended north from Mayfield to I-24 near Calvert City. However, in July 2018, this segment was replaced by an extension of I-69. The rest of the parkway south to the Tennessee border remains Future Interstate 69. History Federal legislation designated the entire length of the Purchase Parkway as I-69 in 2002. On June 6, 2008, President George W. Bush signed HR 1195 (SAFETEA-LU Technical Corrections Act of 2008), reaffirming the I-69 designation for the Purchase Parkway and further authorizing Kentucky to sign the route as such with Federal Highway Administration (FHWA) approval. The Kentucky Transportation Cabinet had planned I-69 signs on the parkway during the summer of 2008, but the FHWA required the KYTC to either upgrade substandard portions of the route or obtain a design waiver before the parkway could be signed as I-69. On July 6, 2018, a 30-mile segment of the parkway was re-designated as Interstate 69, and the parkway was truncated to exit 21 in Mayfield The northernmost stub of the Purchase Parkway between I-24/I-69 and US-62 is now signed as "TO US-62" in the northbound direction and "TO I-24/I-69" in the southbound direction. Originally named Purchase Parkway for the Jackson Purchase area it diagonally traverses, the road was renamed for Julian M. Carroll, a former Kentucky governor from McCracken County, in 2001. The Purchase Parkway carries the unsigned designation of Kentucky Route 9003 (JC 9003). The Mayfield Bypass, which was incorporated into the parkway following its construction, is also signed as US 45 Bypass. As a toll road Except for the Mayfield bypass which remained free, the parkway was originally a toll road, as were all Kentucky parkways. State law requires that toll collection cease when enough tolls are collected to pay off the parkway's construction bonds; which in the case of the Purchase, occurred in 1992.
