Mississippi State University officials say one wing in Ruby Hall will be closed for the entire spring semester while repairs to Oak Hall and Magnolia Hall could be completed in a few days.
The three dormitories suffered water damage this week after sub-freezing temperatures ruptured pipes and flooded the structures.
In Ruby Hall, the dorm's fire suppression system ruptured in the unit's B wing, causing severe damage. Similar incidents occurred in the other two dorms but produced less damage.
MSU officials originally estimated the damage would displace about 450 students from the three dorms, but new assessments put that figure at about 120.
MSU's housing department will assist displaced students transfer to other living options.
