On December 12, the Hubert H. Humphrey Metrodome's inflatable roof collapsed for the first time since 1986 after a heavy snowfall.

The concept has special features, including an inflatable roof that comes out of the centre roof rail.

The game was held at the University of Minnesota's TCF Bank Stadium due to the collapse of the inflatable roof at the Metrodome.

In 1978, Archbold Stadium was demolished to make way for the Carrier Dome, which was to have a domed Teflon-coated, fiberglass inflatable roof.

This indoor Olympic-size swimming pool featured a wire supported inflatable roof that could be removed in the summer.

As the Hubert H. Humphrey Metrodome's inflatable roof collapsed, the two teams had to play at the University of Minnesota in frigid winter weather.

The inflatable roof causes the sound produced to echo many times, exponentially increasing the loudness produced inside.

The inflatable roof was also replaced in 1999 at a cost of $14 million.

Then on Sunday, the Metrodome's inflatable roof collapsed under the weight of 10 feet of snow.

The building was originally planned to be modeled on the Tacoma Dome and have an inflatable roof.
