The big game is just a few days away and while much of the anticipation is about the action that will take place on the field, RC wanted to take a closer look at the roof they’ll all be playing under for a shot at history.

Here’s five things we learned about Atlanta’s Mercedes-Benz Stadium, one of the most interesting roofs in America.

Multi-purpose

The nearly 80,000-seat stadium serves as the home of the NFL’s Atlanta Falcons and Atlanta United FC of Major League Soccer. It replaced the now-demolished Georgia Dome, which was literally next door and home to the Falcons from 1992 until 2016.

Super City

This may be the first Super Bowl ever played at Mercedes-Benz Stadium, but it’s hardly Atlanta’s first time hosting the big show. The aforementioned Georgia Dome with a capacity of more than 71,000, was host to Super Bowls XXVIII in 1994 and XXXIV in 2000. That was the last time the Super Bowl was played in the Atlanta and it was won by the then St. Louis Rams, who defeated the Tennessee Titans 23-16.

What’s with that Roof?

Known for its pioneering 360-degree halo video board — an optical marvel that’s the equivalent of 62,000 square feet of screen, roofing contractors should want to learn more about the roof above. It’s comprised of eight moving panels that each weigh 500 tons and takes 12 motors to operate. The stadium’s opening was delayed several weeks while crews fixed a gap in the roof.

Sticker Shock?

Home Depot mogul and Atlanta Falcons Owner Arthur Blanks boastfully paid nearly $2 billion for the landmark building. The high cost isn’t necessarily passed on to customers, at least via concessions. The stadium is known as the most affordable for snacks among NFL facilities, with sodas a cool $2 and cheeseburgers at a sizzling deal at $5.

Seeing is Not Believing

While opening, the roof is designed to look like a camera shutter. However, each of the eight translucent panels slides back on parallel rails giving the geometric optical illusion of a pinwheel. It reportedly takes eight minutes to open.
