St. Margaret Mercy Hospital in Dyer begins admitting patients Friday for the first time since a flood on Aug. 24.
The hospital was damaged when Plum Creek overflowed into the first floor of the building during severe thunderstorms.
Hospital president Thomas Gryzbek says the State Board of Health toured the hospital and determined that it was ready to return to full service.
The hospital sustained millions of dollars in damage from the flood and was forced to replace flooring, ceilings and more than 5 linear miles of drywall.
Many employees had been working at other area hospitals while the repairs were completed. The emergency room remained open in a temporary location.
