University of Phoenix Stadium

---

Cardinals Stadium is the new football stadium in Glendale, Arizona whose primary tenant is the Arizona Cardinals of the NFL. The new stadium is across the street from the Glendale Arena.

The 63,500-seat stadium (expandable to 72,800) opens for the 2006-2007 NFL season.

The stadium will also be home to the annual Fiesta Bowl and, once every four years, the BCS National Championship Game. In 2008, the stadium will host Super Bowl XLII. It will also be the site for the West Regional Finals of the 2009 NCAA Men's Division I Basketball Tournament.

The facility features a retractable roof as well as the first fully retractable natural grass playing surface built in the United States. An opening on one side of the stadium allows the playing field to move to the exterior of the building so the entire natural turf playing surface can be exposed to daylight when it is not in use. The grass field rolls out of the stadium on a 12-million pound tray built on 13 rails, which takes about an hour to move in and out of the stadium. With the field in the outboard position, the 158,000-square foot floor is unencumbered by the turf and features a built-in utility grid.
