The 2002 federal transportation spending bill includes $500,000 for the study of a proposed Heartland Parkway in Taylor, Marion, Washington and Green counties. Despite its name, this road will probably not be a toll road as my understanding is that federal law prohibits the placing of tolls on any road on which federal money has been spent. Instead, if built, this route would probably be a four lane reconstruction of KY 55. The proposed road would connect to the Louie B. Nunn Cumberland Parkway near Columbia and the Blue Grass Parkway near Springfield. More details can be found here , here , and here  (no longer online).
