This project was for the £2m second phase of a major reconfiguration project to improve the accident and emergency department at Hull Royal Infirmary. The work also involved construction of a new access road at the rear of the hospital to allow construction of an extension as part of the re-development.
A total of £7m was spent by the Health Trust extending the department space to double its previous size. It also has18 treatment areas instead of five.
There are separate areas for children and people with minor and major injuries.
The department was revamped to allow patients to be treated more efficiently, the hospital said.
Staff currently previously had to cope with 120,000 patients each year in a hospital that was originally built to treat about 50,000.
