Motorists are facing long delays after a truck rolled over on the Pacific Highway north of Sydney.
Traffic is backed up on the M1 Pacific Highway after a tanker truck carrying bitumen rolled over near Berowra around 12.25pm, trapping the driver inside.
Rescue workers managed to free the driver at 1.30pm and he was airlifted to hospital in a serious condition, but the crash has caused tailbacks in both directions.
Peak hour commuters are facing traffic chaos this evening after a truck overturned on the Pacific Highway around 12.35pm, causing tailbacks in both directions
Two lanes were closed northbound at the time of the crash, and while they were all reopen on Thursday afternoon, traffic was still queuing for 6km.
A Sydney Morning Herald reporter who drove the route at around 3pm said it took him 90 minutes to reach Berowra, a journey which typically takes an hour.
Meanwhile one southbound lane has been closed with queues stretching for 2km.
Queues heading north out of Sydney are around 6km long, according to a Traffic New South Wales spokesman, while those heading south around 2km
The truck driver had to be cut free after the accident and was airlifted to hospital in a serious condition. The truck will remain on the road until after peak hour, when it will be removed
A spokesman for Traffic New South Wales said the truck, which has come to rest on the grass meridian, will remain in place until after peak hour.
Emergency services will also remain in place until the evening, when a crane will be brought in to clear the truck away.
Only after that will highway crews be able to clean the road and carry out safety checks before traffic can return to normal.
