Earlier this week the NRMA released an audit of the Princes Highway from Dapto to the Victorian border.

The audit said a quicker way to  improve the road would be a staged implementation of the Albion Park Rail bypass.

Under the proposal, a two-lane bypass would be built for southbound traffic while northbound traffic would continue to use the existing highway.

However, Minister for the Illawarra John Ajaka said the government wasn’t looking at building a partial bypass.

‘‘The NSW government has displayed a preferred option for a full bypass of Albion Park Rail and is targeting planning approval in 2016 to achieve improved traffic efficiency,’’ Mr Ajaka said.

The idea of building the bypass in stages also found no support from local member, Shellharbour Labor MP Anna Watson.

Ms Watson said it would create ‘‘traffic congestion mayhem’’.

‘‘The staged bypass proposal by the NRMA will simply create massive pinch points of congestion along Tongarra Road at Albion Park and further along the Princes Highway towards the Oak Flats Interchange,’’ Ms Watson said.

She said the bypass needed to be completed as a ‘‘job lot’’.

‘‘The bypass estimated to cost $600million will take up to three years to finish once started,’’ she said.

‘‘Any proposal to stage the construction of the Albion Park Rail bypass will create traffic congestion mayhem across Albion Park.’’

The NRMA audit also said the Princes Highway south of Jervis Bay was dangerous as the incidence of crashes was too high when the volume of traffic was taken into account.

But Mr Ajaka said the government had already spent more than $200million ‘‘south of Nowra’’.

This included $72million for the South Nowra upgrade, the  $55million Bega bypass and  $35million for the realignment of the highway at Victoria Creek.
