The new Cardinals Stadium will be open in time for the 2006 season. The world-class venue will not only feature a retractable roof but will also be the first in North America to feature a fully retractable grass playing surface. In addition to hosting Cardinals games, the stadium will host the Fiesta Bowl annually as well as the BCS National Championship Game in January of 2007 and Super Bowl XLII in February of 2008. The stadium will have a seating capacity of approximately 63,000 fans with the ability to expand to 73,000 for marquee events.

Is it a coiled rattlesnake? Or a barrel cactus?

"The exterior design of the stadium has been created by world-renowned architect Peter Eisenman, along with HOK Sport and should become a landmark facility for Arizona. The basic form of the design takes its cue from a barrel cactus and offers alternating vertical slots with smooth panels. In addition, the translucent “Bird-Air” fabric roof will allow the stadium to have an open, airy feel even when the roof is closed. The roof has two large retractable panels that will uncover the entire playing field while providing maximum shading for fans. The roof can be closed and the facility air conditioned in the hot months, while the roof can be opened to take advantage of the Valley’s world-famous climate in cooler months..."

The building of this stadium was featured recently on Discovery Channel's EXTREME ENGINEERING.
