How Many NFL Stadiums Have Dome Structures?

February 15, 2024

The NFL has a number of teams that play in domed stadiums. These stadiums take the weather out of the equation and allow for a much more controlled environment for the players to play in. It is important to note that it is still very difficult for dome teams to win championships. This is probably because they are not used to playing in the cold weather or in a snow storm.

The first domed stadium opened in 1967 and was built to replace the Minnesota Vikings Hubert H. Humphrey Metrodome. The project took more than 2.5 years to complete and cost over $150 million. In its first three years, the stadium hosted 4.64 million visitors. The next year the stadium hosted the NCAA men's basketball tournament Final Four.

Domes were designed by a New York architect named David Geiger, who drew inspiration from geometrician and inventor R. Buckminster Fuller. He also recalled a trip to the Colosseum in Rome, where he saw how slaves pulled a canvas velarium, or awning, across the structure when it was raining.

The domes were a radical innovation at the time, but they were not without their problems. In addition to the obvious cost of building and operating a dome, the structure also takes up a lot of space. A dome can be as big as a two-lane road, and it takes a massive amount of concrete to support it. One former general manager of a Superdome, who now runs a public events management company in Houston, explains that the cost of the structure and a retractable roof can add between $100 million and $150 million to an NFL stadium project.
