Lucas Oil Stadium
Indianapolis, Indiana
The 63,000-seat Lucas Oil Stadium will host the Indianapolis Colts NFL franchise, as well as NCAA Final Fours, conventions, concerts and special events. This will be the first U.S. retractable roof that is supported on multiple, parallel supports.
Two 596-foot by 163-foot moving panels are supported on steel wheels atop two opposing sets of sloping steel rails. The rails are supported atop five sloping, gabled box trusses that span between two enormous 752-foot-long superframes that span the length of the stadium.
The 14,300 tons of structural steel roof panels are secured with steel cables that are attached to a winding drum at the roof peak at each truss. When activated, computer-controlled electric motors turn the drums to reel in the roof using the cables, allowing the roof structure to slide down the roof slope and over the fixed lower roof panels.
