The NSW government has still not released a safety study of Appin Road months after it was completed.
In December last year Roads Minister Duncan Gay met Wollondilly MP Jai Rowell and representatives of Campbelltown, Wollondilly and Wollongong councils to discuss safety issues on Appin Road.
After that meeting Mr Gay said the Centre for Road Safety, with support from Roads and Maritime Services, would conduct a review of the road earlier this year.
The study was prompted by two fatalities on the road last year.
In September, eight-year-old Brock Anderson died when his father's Holden Commodore and a Subaru Impreza collided 10 kilometres south-east of Appin.
A month later, 19-year-old Thomas Scott-Dobie died when his Hyundai coupe and a Holden Rodeo utility collided four kilometres east of the West Cliff Colliery entrance.
In June, a spokesman from Transport for NSW told the Mercury: "The safety review on Appin Road is complete and the report will be released shortly."
However, three months later, there is no sign of it.
This week, a spokeswoman from Transport for NSW again told the Mercury "the report will be released shortly".
The spokeswoman said the review included significant analysis of the road and would "ultimately improve safety outcomes for all road users".
"This work cannot be rushed," she said.
"The route safety review has involved a detailed analysis of crash history and an assessment of the road characteristics and roadside from both a behavioural and engineering perspective.
"New safety treatments for Appin Road are being considered and a program of work will be developed that is achievable and feasible to increase the safety of Appin Road," she said.
Opposition roads spokesman and Keira MP Ryan Park wasn't surprised by the delay, claiming the government spent a lot of time doing reviews.
"The problem with that is it actually forgets where it's up to and it delivers very little in terms of concrete action," Mr Park said.
"It can think that by putting people off by saying they're doing a review that that's the end of the story.
"This is a road that has a large number of vehicles, including heavy vehicles, travelling to and from the region each and every single day.
"That's why it's so concerning. It's also got a very bad crash statistic and fatality rate."
At the same time as the safety study, the Centre for Road Safety and RMS also carried out a review of the speed limits along the road.
The review, released earlier this year, found the existing 50km/h zone through Appin township was suitable, as were the 80km/h and 100km/h speeds along other sections of the road.
