KENTUCKY’S FIRST EXPERIENCE WITH FULL CLOSURES

I-65 in Louisville, Kentucky

A 90 Day Project in 107 Hours

traditional traffic control vs full closure
TRADITIONAL TRAFFIC CONTROL VS. FULL CLOSURE
  • Using Traditional methods, work would have taken approximately 90 working days as opposed to two weekends for the full closure.
  • Using traditional methods, estimates showed severe traffic congestion throughout the day (6am-6pm) .
  • Using a full closure has larger impact on the traveling public, but for a much shorter duration. This holds with the Cabinet’s philosophy of, “Get In, Get Out, & Stay Out.”
  • Using a full closure gave the Cabinet the opportunity to complete supplemental needed repairs in the work zone.
