Steel Structure Trivia: Super Bowl Stadium

Houston’s NRG Stadium (formerly Reliant Stadium) will play host to Super Bowl 51 next Sunday, February 5. When it opened in 2002, this 1,900,000-sq.-ft stadium was the largest in the NFL and also the league’s first facility to have a retractable roof, made possible by innovative engineering and an efficient steel structural system that is based around two large super-trusses that span along either sideline of the field.

Our January trivia question is:

How many acres does the retractable roof structure span at NRG Stadium?

  1. 1/2
  2. 2
  3. 4
  4. 8


The correct answer is 4 acres. Congratulations to our winner: Mounir Matta, structural design manager - building projects at Lusail Real Estate Development Company!
