In 2014 the $400 million Campus Crossroads expansion renovated the structure and added three buildings onto the stadium: the Duncan Student Center, which hosts student recreational and dining facilities, O'Neill Hall, which houses the university's music department, and Corbett Family Hall, which hosts the psychology and anthropology departments. In addition, the three buildings house premium stadium seating, press boxes, and event spaces.
O'Neill Hall hosts the Department of Music and Sacred Music, including a 174-seat recital and performance hall, the music library, lecture halls, classrooms, rehearsal and seminar rooms, offices, faculty offices, a music lab for studio production, and practice rooms. It also houses stadium and sport-related spaces and a club lounge. O'Neill Hall is built around the Frank Leahy Gate, which is the grand entrance to stadium, and has a 106,809 square footage.
