The fiancee of the truck driver involved in Monday's horror crash has attacked the State Government for failing to fix the dangerous stretch of road where the crash occurred.
"Because the Government couldn't be bothered fixing the road, innocent people are losing the ones they love," Nicole Colak, 26, said.
"My son will never, ever know his father because it's too important for those bastards to keep the money in their pocket."

Mr Carolan also had two boys to a previous relationship - Bradley, 11, and Jamie, 9.
When asked if she wanted to say anything, she said of the Government: "Thanks for killing my fiance, because if they had done something about (the road) a long time ago this wouldn't have happened."
Mr Carolan, 36, had left the Cootes Transport Group depot at Parramatta some time after 1pm and was 15 minutes from his destination at Batemans Bay when the crash occurred.
Driving a tanker full of diesel, Mr Carolan was negotiating a bend near Pebbly Beach Rd north of East Lynne when the crash occurred.
It is as yet unclear what caused the accident, but Mr Carolan's fiancee said she was told by police on Monday night that he had swerved to avoid an oncoming car, which had been overtaking another vehicle.
Police were publicly less specific about the case, saying they did not know why he had crossed into oncoming traffic.
But for some reason, Mr Carolan's truck lost control and crossed into north-bound traffic. It collided with three cars before exploding on the side of the road, killing Mr Carolan and two sisters, Makeely and Jordon Bridge.
The massive explosion was heard 3km away and caused a thick black plume of smoke to rise above the area.
Ms Colak and Mr Carolan had been in a 41/2-year relationship and had planned to marry by the end of the year.
"He was one of the best blokes I've ever known - nice, funny. Just a genuinely decent, hard-working man," Ms Colak said.
Amid tears and sobs, Ms Colak said she had last seen her fiance when he left for work on Monday.
"He had a shower, kissed me and his newborn son goodbye. I told him what I tell him every morning, 'I love you, be careful', and then he went to work," she said.
She knew something was wrong when she tried to call him in the evening and his phone was off.
The family called Cootes Transport and eventually they confirmed Mr Carolan was the truck driver involved, but Ms Colak wasn't certain of his death until a police officer came to the family's Narellan Vale home about 11pm.
Mr Carolan had been planning to take the next month off work, with his two other sons due to fly down from Queensland to spend their school holidays with him, she said.
The managing director of the company that owns Cootes, International Energy Services, said staff at the company were grieving for Mr Carolan and would be assisting police with their investigation.
