A driver has been left in a serious condition following a crash on the Sydney Harbour Bridge, one of Australia's busiest and most iconic crossings. The incident caused significant disruption, with traffic banked up for several kilometres as emergency services responded to the scene.

Details of the crash remain limited, but the driver involved sustained serious injuries and was treated at the scene before being taken for medical care. The bridge, a critical commuter route linking Sydney's northern suburbs to the central business district, saw lengthy delays as authorities worked to clear the wreckage and restore normal traffic flow.
