The rail yard's shift horn was saved and installed in the stadium's north end zone scoreboard and is sounded whenever the Cardinals score.

In 2000, Central Avenue was widened and extended from Taylor Boulevard to Crittenden Drive, a major redevelopment project.

A 20-year, $41.3 million naming rights agreement between the university and financial institution was officially announced during a U of L board of trustees meeting.

Former head coach Charlie Strong stated in September 2013 that he would like to see the stadium enclosed at the North end zone.

[17] The University of Louisville announced on December 1, 2014, that supporters matched a $3 million gift given by Thorntons Inc. to construct a new academic center underneath the Norton Terrace.

The 40,000-square-foot (3,700 m2) facility includes tutorial space, laboratories, and offices and classrooms to serve more than 750 student-athletes across the university's 23 sports.

The venue overlooks the school's new Jim Patterson Stadium and Jewish Hospital Sports Medicine complex, which was completed in 2005.

A new red LED scoreboard was also installed in the south end zone, as was a lighted "University of Louisville" sign around the upper rim of the exterior of the east stands, which increases the stadium's visibility from Interstate 65.[when?]

Also at the sound end is a bronze statue of Johnny Unitas, NFL great and the most famous football alumnus of the university.
