The new fixed roof structure, made of more than 9,000 tons of steel, consists of two 177 meters east-west trusses and four 144 meters cross trusses. The retractable roof slides on the inner cross trusses, divided into two panels composed of five 72×7 meters inflatable cushions between six 72.5 meters-span steel-composite hybrid trusses. At the ends are motorized bogies that carry out the translation and integrate the lifting mechanism.
