NSW Roads and Maritime Services have decided the Sims Road access will run alongside the upgraded highway to join the Belinda Street interchange.

Princes Highway Action for Safety Group chairman Robert Christie welcomed the choice - the other option would have run through a landholder’s property.

“That was a major win and a really good result,” he said.

But the access decisions for the Mt Pleasant section of the upgrade were not as warmly received.

Three properties on the eastern side of the highway will be linked, but residents will still have to enter and exit the road directly from the highway.

Properties further down the road will link to an access road on the western side of the highway via an underpass before linking to the Rose Valley interchange.

Mr Christie said linking all the properties to the Rose Valley interchange would have been a better result and to say he was disappointed was a “gross understatement”.

“There are seven direct accesses remaining and of those, two are the most dangerous - the one at Mt Pleasant and the one at the cutting (between Gerringong and Toolijooa),” he said.

He said keeping direct accesses at Mt Pleasant meant there would not be enough sight distance for traffic heading southbound to travel at 100km an hour.

“It’ll have to be 80km an hour and you’ve got to wonder why you would build it if the traffic’s not going any faster,” he said.

“I think there’ll be a serious accident and if there is, people will look back and wonder why the RMS didn’t put the access in when it had the opportunity.”

Frank Tynan, whose property will be one of the three affected by the direct access road, said he was “thankful for the small mercies”.

“At least we will have access to each other and it does ensure we will have access to waste collection and postal services,” he said.
