BLACKTOWN Hospital is undergoing a transformation that will make it a world-class health facility, its management says, but visitors to the site should be prepared for some major disruptions.
Hospital general manager Andrew Newton said that when complete after a $324 million redevelopment, the hospital would be a state-of-the-art medical facility.
The new building and refurbished existing building will include an additional 180 beds.
A new mental health centre will be built as well as a new 600-space multi-level car park.
It will feature a dedicated cancer centre, with radiation oncology.
The hospital will work closely with the University of Western Sydney, which has a new campus on the site, to attract expert medical professionals and to give staff the opportunity to teach, research and practise clinical work.
Transition manager Peter Rophail said the redevelopment would completely change the way health services were delivered in Blacktown.
"When we reopen we will be able to deliver world-class health services here in Blacktown," he said.
"There is going to be some disruption, we're not going to hide that, there's going to be a bit of pain for everyone [during construction] but it's going to be worth it."
Car parks have been excavated, reducing the number of spaces for people trying to access the hospital.
Mr Newton said construction would cause people delays but he was confident the work had been planned efficiently to reduce the interference.
