Trahan Architects has unveiled renderings for a recently approved $450 million upgrade package for the historic Superdome football stadium in New Orleans. 

The Superdome, one of the few remaining Modernist football stadiums from the post-World War II era, was designed by local New Orleans firm Curtis and Davis in 1975 and is considered among the more iconic structures in the city. The building is topped by the largest single-span dome in the country, Nola.com reports, and was last upgraded in the aftermath of Hurricane Katrina. Those renovations, as it turns out, were also carried out by Trahan Architects. 

Trey Trahan, founder and CEO of the firm tells Nola.com, "The strategy here has been to enhance the quality of experience for the spectator at all levels: general seats, club, the suites, and now there is going to be SROs [Standing Room Only zones]."

The 76,000-seat Mercedes-Benz Superdome, as the structure is known today, will receive an expansive interior overhaul that will bring new field-level endzone boxes, a series of entry atriums that will replace the complex's convoluted existing ramped entry system. Plans call for the first phase of the project to bring a slew of back-of-house improvements, including a new commercial kitchen facility. The second phase will institute spectator-facing improvements. 

Back then, TSA student Amanda Keith decided to nominate the building for the National Register as part of the program's Economics and Business of Preservation class. After the semester ended, Keith continued with the nomination, eventually gaining support for the effort from the Louisiana National Register Review Committee and the National Parks Service. 

Remarking her work pursuing the project beyond the required coursework, Keith told Nola.com, "I decided to just keep going with and actually nominate it for real," adding, "I really love the building ... I think it's such a beautiful building. It's great modernist design."
