The Bass Highway has been closed after two utes crashed at the end of the Illawarra Road on-ramp this morning.
Authorities have shut down the highway at Carrick in both directions and are urging motorists to avoid the area.
The crash happened in a section marked with double white lines and comes as thousands head to Carrick for the Party in the Paddock music festival.
The extent of injuries is not yet known, though police say minor ones have been reported.
Inspector Grant Twining said earlier this week there would be a strong police presence in the area throughout the event.
“At the conclusion of the festival, police will conduct a large scale random breath testing operation for motorists leaving the site,” he said.
“Our aim is to get everyone home safely and that includes testing drivers and removing those affected by alcohol and drugs from the roads.”
