PATIENTS and visitors can expect minor changes in the months ahead, all of which will be signposted.
The emergency department will remain open 24 hours a day, seven days a week.
"There will be work going on everywhere you look," Mr Peter Rophail said.
"We've planned the expansion very carefully to ensure there are no changes to existing services. The first part is external work and will not affect patients for the first four to five months. There will also be infrastructure upgrades to power to keep the hospital running long term."
