The verdict is in: the worst roads in NSW

The Kings Highway at Braidwood came in at number six, and the Barton Highway at Murrumbateman was number eight.

More than 10,000 motorists from NSW and the ACT were questioned by the NRMA, which is campaigning for better roads.

Just under seven per cent (6.7 per cent) voted the Pacific Highway the worst road in the state in terms of congestion, insufficient lanes and bad road surface.

It was followed by Parramatta Road (4.7 per cent) and Pennant Hills Road (4.4 per cent).

NRMA Motoring and Services president Wendy Machin said it was unacceptable that duplication of the highway was still unfinished, more than 20 years after horrific bus crashes at Kempsey and Grafton.

"However, significant funding from both levels of government has been allocated to the Pacific Highway after it was consistently flagged the worst road by motorists in NRMA's annual Seeing Red on Roads campaign," she said.

Almost 10 per cent of road users said Parramatta Road was Sydney's worst road, ahead of Pennant Hills Road and the M4 Western Motorway.
