Jack Trice Stadium (originally Cyclone Stadium and formerly Jack Trice Field) is a stadium, in Ames, Iowa, United States. It is primarily used for college football, and is the home field of the Iowa State Cyclones. It opened on September 20, 1975, with a 17–12 win over Air Force.
It is the third-largest stadium by capacity in the Big 12 Conference and the third-newest in the conference, behind only Milan Puskar Stadium of West Virginia (which had its design based on Jack Trice Stadium) and Baylor's McLane Stadium. Including hillside seats in the corners of the stadium, the facility's official capacity is 61,500. The school announced in May 2014 a planned expansion to 61,500.
The current record for single-game attendance, 61,500, was set on September 5, 2015, when the Cyclones defeated the University of Northern Iowa by a score of 31-7.
Jack Trice Stadium replaced Clyde Williams Field, which had been in use from 1914 through 1974. Williams Field was closed in 1975 and razed in 1978, and Martin and Eaton residence halls now stand on the ground.(Wikipedia)
