The $85.7 million renovation of Arizona Stadium's north end zone was approved today by the Arizona Board of Regents, allowing the Wildcats to begin raising private funds to pay for it.

The three-pronged plan will move the scoreboard from the north end zone to the south, clearing the way for a structure that will hold football offices, about 5,000 seats and a luxury loge area. Arizona Stadium's lights will also be replaced, and Jimenez Practice Field will be enlarged.

Construction ideally would begin in spring 2011, UA officials said last week.

Private donations will pay for the project. In November, the UA received a $10 million gift from Jeff and Sharon Stevens, and that money has been earmarked for the stadium project.
