The retractable roof, comprising 9 million pounds of structural steel, operates on the same tried-and-true technology found in drawbridges and overhead traveling cranes. A pair of 200-horsepower motors open or close the roof in slightly more than four minutes, utilizing more than four miles of cable strung through a pulley system. Each half of the roof consists of three moveable trusses which telescope over a fixed end truss. The east and west sides of the roof can operate either in unison or independently. Either side of the roof can be opened to any position in order to maximize sunlight on the turf and minimize it on the interior steel and concrete.
