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 it the parkway could be signed as I-69.
