Following the 2004 season, the university spent approximately $47 million on an expansion to the north end zone, which was completed days before the 2006 opener against Hawaii. It added a new upper deck to the North end zone area, complete with three different levels of skyboxes, which collectively are known as "The Zone", which brought the number of skyboxes in the stadium to 123. Two large display screens by Daktronics were placed in each corner of the north end zone, and LCD ribbon screens, tall by wide, were placed along the front edge of the east and west upper decks.
