The northbound lanes of the Bruce Highway through Cooroy were closed to traffic following a two-vehicle traffic crash about 7am on Tuesday morning that left a teenage boy with life-threatening head and chest injuries.
Traffic stopped for a couple of hours as emergency services teams rushed to aid the injured youth.
Southbound lanes of the highway were also closed for about 20 minutes to enable LifeFlight paramedics to attend.
The Sunshine Coast-based LifeFlight aeromedical crew airlifted the teenager to hospital after his car and a crane truck collided.
Queensland Police Service (QPS) officers closed the highway and Queensland Fire Department firefighters cut the teenager from his car.
The LifeFlight helicopter landed on the highway close to the scene.
The LifeFlight critical care doctor and Queensland Ambulance Service (QAS) flight paramedic worked with local QAS paramedics to treat the patient who was intubated and flown to Royal Brisbane and Women’s Hospital (RBWH) in a critical condition.
