The north bowl seating section was added in 1927 to give the stadium its horseshoe shape which it retains today.

The press box and scholarship suites saw significant improvement and expansion in 1999, and the MegaVision video board was installed in the same year.

The stadium was renovated in August 2017 with new seats, a new touchdown club behind the north end zone, and the outside walls with banners.

On August 15, 2023, University of Kansas athletics unveiled plans for a complete rebuild of the stadium that would begin immediately following the 2023 season.

The second phase is the reconstruction of the east stands, combined with a mixed-use facility that will include a hotel, restaurants, and retail.

The east side renovations would move the stands 80 to 100 feet west, allowing space for the project's other features.

Another complication for the second phase involves parking—the east side houses the stadium's two largest parking lots.

At the Jayhawks' November 5, 2005 streak-snapping 40–15 victory over Nebraska, it was announced that that attendance record was broken, with a standing-room-only crowd of 51,750.

The Relays annually see top area high school and intercollegiate competitors, and the open events often draw Olympic runners such as Maurice Greene and Marion Jones.

The Kansas Relays is the location where world-record holder Justin Gatlin tested positive for performance-enhancing drugs in 2006.

In 2014, the Kansas Relays left Memorial Stadium and moved to Rock Chalk Park, a new multi-sport complex located northwest of the KU campus.
