A six-month refurbishment of Stepping Hill Hospital's emergency department is underway.
The £1.2 million building programme will improve the patient waiting areas, add a new reception area and create additional consulting and treatment rooms.
Currently, the A&E department at the hospital provides care and treatment for over 90,000 patients per year, including many from the High Peak area.
Colin Wasson, Medical Director for Stockport NHS Foundation Trust, said “Our A&E department has come under increasing pressure in recent years due to the increasingly complex needs of the population.
"This renovation will provide much needed support to our staff and our patients in providing care sooner and in a more effective environment."
The department will remain fully operational while the building work is ongoing. Patients will need to use an alternative entrance to the department for several weeks later in the year, which will be clearly signposted from the old entrance.
"We ask patients to bear with us over the coming months, as some small disruption leads to a big improvement,” Mr Wasson added.
Work on the A&E entrance and waiting area is due to be finished in December, with a single-storey extension scheduled for completion in February.
