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 Cabinets
  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.
