NSW truck crash causes traffic chaos

Motorists on the Pacific Motorway are facing lengthy delays after a truck crashed at Wyong on the NSW Central Coast.

All southbound lanes of the motorway in the area were closed after the truck veered into a traffic barrier on Saturday morning.

The driver was uninjured but parts of the truck were strewn across the highway.

One lane on the highway has since reopened and police diversions have been lifted.

However traffic is still queued for more than 10 kilometres as emergency crews continue the clean up.

Drivers are advised to allow plenty of extra travel time.
