Construction on the original 53,000-seat stadium was completed Oct. 5, 1929, at a cost of $497,151.42. Original construction took six months, but the stadium has undergone several facelifts since. Seats were added to the south end zone in 1956, raising the capacity to 60,000. The north end zone was enclosed and capacity increased to 66,000 prior to the 1983 season. With three expansion projects completed since that time, the seating capacity at Kinnick Stadium reached 70,585. Kinnick Stadium has 20 miles of bleacher seats and is 79 rows high on each side. The seating upgrades that were part of the Kinnick Edge project reduced the current capacity to 69,250.
Beside the expansions, an artificial surface was installed in 1972. That carpet was replaced in 1981. Prior to the 1989 season a natural grass playing field, Prescription Athletic Turf, was installed. The playing surface was replaced with new sod prior to 1997 and 2005.
The playing surface was replaced prior to the 2009 season, this time with state-of-the-art Field Turf, and replaced again prior to the 2017 and 2019 seasons. Permanent practice lights were installed prior to the 2012 season and upgraded to provide broadcast-quality lighting prior to the 2015 season.
The playing surface in Kinnick Stadium in 2017 featured an Iowa logo for the first time since the conclusion of the 1980 football season, as the Tigerhawk was installed at midfield. The stadium playing surface was without a University logo since a block “I” adorned the center of the field from 1972 through 1980. Artificial turf was first installed prior to the 1972 season and the block “I” appeared at midfield until a new surface was installed prior to the 1981 season, without a logo at midfield.
The original five floor press box was constructed in 1958 at a cost of $490,628.62, and was located between the 25 yard lines on the west side of the stadium. Between 1995 and 1999, the Kinnick Stadium press box underwent a $3 million improvement and renovation project, which included the addition of 18 private viewing suites and the remodeling of all five levels. The original press box was demolished in December, 2005.
