Mercedes-Benz Stadium is a multi-purpose retractable roof stadium located in Atlanta, Georgia. The home of the Atlanta Falcons of the National Football League (NFL) and the Atlanta United FC of Major League Soccer (MLS), it replaced the adjacent Georgia Dome, the Falcons’ home stadium for a quarter century, from 1992 through 2016.
Opened in 2017, Mercedes-Benz Stadium is owned by the state of Georgia through the Georgia World Congress Center Authority, and operated by AMB Group, the parent organization of the Falcons and Atlanta United. The total cost is estimated at $1.6 billion, as of June 2016. The stadium officially opened on August 26 with a Falcons preseason game against the Arizona Cardinals, despite the retractable roof system being incomplete.

The winning design, submitted by HOK, featured an eight-panel retractable roof that resembled a pinwheel, and a glass wall that would open with the roof to allow in fresh air.
The roof design included eight triangular translucent panels, that when opened would create the illusion of a bird’s wings extended. Surrounding the opening of the roof would be a halo video board that would enclose the playing surface, stretching from one of the 10-yard lines to the other and then curving around the end zones to complete the oval. Each of the eight panels operates on two parallel rails; one rail is responsible for moving the panel while the other rail stabilizes the panel.
