By 1925, the east and south stands were completed, making the stadium a 30,000-seat horseshoe with an open north end. The west stands were rebuilt and a large press box was added in 1947, bringing capacity up to 44,000. The original all-steel 4,105-seat North stands were erected in 1958, and in 1962 and 1968 the upper decks were added to the East and West sides, respectively, bringing capacity to its all-time high of 58,121. Following this, Grant Field hosted the inaugural Peach Bowl in 1968, and would serve as its venue from 1968 to 1970. Grant Field also served as the home field for the Atlanta Apollos of the North American Soccer League for their 1973 season. In August 1984, the stadium hosted the annual Drum Corps International World Championships. In 1985 the South stands were razed to make room for the William C. Wardlaw Center, a modern field house and athletic office facility to replace the facilities in the old Heisman Gym, which was located just to the north of the stadium; the construction of the Wardlaw Center reduced the stadium's capacity to 46,000.
