north tunnel entrances. Eight new concession stands were added, along with more than 60 new toilets in the women's restrooms, 30 new water fountains, handrails on all aisles of the upper decks, new speakers in all restrooms, and a new public address system. Phase two replaced the obsolete displays and sound system of the Lloyd Noble Center. The final phase was completed prior to the 2008 season and included replacement of the stadium's south scoreboard and sound system within the existing structure. The new displays are compatible with high-definition television equipment, although no HD cameras were purchased during the project. On March 10, 2015, the University of Oklahoma board of regents approved the initial construction of "Phase 1" to renovate Gaylord Family Oklahoma Memorial Stadium. The renovation is expected to cost approximately $160 million and anticipated completion is just prior to the start of the 2016 football season. Due to uncertain economic conditions, the board of regents decided to start with "Phase 1" (which will focus primarily on the south endzone, football offices, training center and weight room), and proceed to "Phase 2" (which will focus on the west side of the stadium, including the press box, club seats and new facade. As well as various improvements to restrooms, escalators and concessions) at a later date, when the economic conditions have improved. The first phase of construction will bowl in the south endzone, and bring the total capacity to 83,489.
