All lanes have reopened on the Pacific Motorway at Coomera after a serious traffic incident on Thursday afternoon.
Emergency services were called to the incident, between exit 54 and 45, just before midday.
Paramedics did not treat any patients.
At 12.30, police said it would be several hours before the scene was cleared and had put diversions in place.
Motorists were urged to avoid the area as there were "significant congestions", police said.
