You are way off on the cost of a retractable roof.I think they should build a retractable roof and they certainly could. The movable part of JerryWorld is not held up by the concrete, it is held up by the giant curved steel structure. Same with reliant Stadium, supported by Steel structures. Why not blow out the West end of the dome and build new locker rooms, add some nice SU shops a couple restaurants that are open all the time for students and the public. To generate revenue beyond gamedays and lure the public in. Build a steel structure over the top of the current concrete sarcophagus that will support the weight of a movable roof, an exoskeleton if you will. Would this be as expensive as constructing a new dome, no. Would it probably run around 35-40 million, probably. Building anything in Syracuse is not as expensive as building in other places, keep that in mind.
But not 100-150 million to replace it on South Campus.
The Metrodome, built for $55 million and opened in 1982, has had its moments. The first three times the roof tore were in the 1980s, after heavy snows and hurricane-force winds.
In 1989 the Sports Facilities Commission looked at possibly replacing the fabric dome with a retractable roof but dropped the idea when it learned the price tag: $240 million.
