UK Chancellor of the Exchequer George Osborne has approved the £420m investment programme for the redevelopment of Royal Sussex County hospital in Brighton.
The Royal Sussex County hospital has 753 beds and provides a range of surgical treatments for major trauma and emergencies.
However, the existing buildings at the site are old and date back to the 19th century.
As part of the redevelopment programme, the old buildings at the hospital will be demolished and replaced with modern facilities.
The redevelopment will also expand the hospital's bed capacity by 100 and improve the neurosciences and cancer centres at the hospital.
Osborne said he is pleased to have been able to greenlight the investment for the much-needed redevelopment project.
"Bringing the buildings and facilities of this venerated hospital up to modern standards will enhance and improve patients' care and experience," Osborne said.
"This investment once again demonstrates our commitment to protect and support the NHS. It is only possible because our long-term economic plan has restored control of our public finances."
The project will be fully financed from public funds, which is subject to final approvals, and as part of the Department of Health's capital investment budget.
Work on the project is expected to begin later in the year and scheduled to be completed by 2024.
