State transportation funds are being used for an anti-litter ad campaign in the Louisville area: Courier-Journal: Anti-trash Push Starts (June 4, 2004) 

The funding was approved during the 2002 Regular Session of the state legislature.

Every two years a Six Year Highway Plan is prepared and approved by Kentucky's legislature. The 2002 Recommended Six Year Highway Plan  has been posted on the KYTC website. The KYTC is concerned that funding might not be available to complete all of the projects because a gas tax increase was not passed by the state legislature. Instead the legislature directed the Governor to use the highway reserve fund to pay for improvements. This fund will soon be depleted. This Courier-Journal article  and this KYTC press release  have more information about the Six Year Plan and the transportation budget.
