University Hospital Galway has apologised for disruption and additional delays as the Emergency Department moves to a new location this weekend.
The service began relocating to a temporary Emergency Department at the front of the hospital yesterday.
UHG has requested that people only attend the Emergency Department at the hospital if it is an emergency situation over this weekend.
They are asking that people attend their GP or out of hours service in the first instance if at all possible.
The Roscommon Injury Unit is also open from 8am to 8pm to treat a range of injuries in both adults and children over five years of age.
