Carbondale (AP) – Southern Illinois University official says one of the Carbondale campus’s iconic 17-story towers will reopen to students next fall. The university has decided to close University Hall and reopen Neely Hall, The Southern Illinoisan reported. Neely Hall was one of three high rise dorms, known as the towers, which were closed for the 2018-2019 school year after an enrollment decline left the university unable to fill them. Enrollment at the Carbondale campus dropped to 12,817 students this fall semester. The 12 percent drop follows enrollment declines of 7.5 percent in 2016 and 9 percent in 2017. The campus’s enrollment is about half of its 1991 peak of 24,869 students.
