Patients and visitors accessing Bundaberg Hospital will experience changed conditions while works near the hospital's main entrance are under way.
Wide Bay Hospital and Health Service is advising works have today begun to upgrade one of the main hospital building's air-conditioning systems.
Chief executive Debbie Carroll says it means fencing and scaffolding will be in place along the southern side of the building.
That is adjacent to the internal road that leads to the hospital's main entrance.
"As a result, vehicle access along the internal road will operate as a single lane during the works with signage in place to alert motorists of the changed conditions," Ms Carroll says.
"While mostly used by staff, the footpath directly adjacent to the building will also be temporarily closed, so pedestrians will need to access the hospital via Bourbong Street.
"We appreciate everyone’s patience and cooperation while these works are underway."
The works are expected to take about one month, weather permitting.
