One of the workers helping to construct the Newcastle Inner City Bypass Extension is in hospital following a workplace accident at the site overnight.
Emergency services were called to the intersection of Lookout Road and McCaffrey Drive at New Lambton Heights around 10pm to reports a truck had rolled, trapping the driver inside.
The man, believed to be in his 60s, was eventually extricated by Police Rescue and Fire & Rescue NSW crews.
Paramedics quickly transported the patient down the road to the John Hunter Hospital in a serious condition suffering spinal injuries.
Safework NSW has launched an investigation.
