Super Bowl LVII expected to mean big business in Arizona, economic growth and visitors from all over

A lot has changed since Arizona last hosted a Super Bowl. It was No. Super Bowl XLIX, to be exact. Back in 2015, most of the festivities leading up to the game happened in downtown Phoenix. Cityscape was just an asphalt lot then, with a rock wall, and stages for concerts. Now, there's a supermarket, apartments and a hotel.
