Partial construction of the interchange at the northern end of the project – which consists of two roundabouts – would restrict Dapto access to the bypass to only one direction.

This is an option which Roads and Maritime Services documents suggest Parliamentary Secretary for the Illawarra Gareth Ward supports.

On Monday, the Mercury ran details of a meeting Mr Ward had with Roads and Maritime Services staffers in which it was claimed Mr Ward was unhappy with the possibility the western roundabout in the interchange would not be built.

The details state that Mr Ward would “push for further funding to get this built”.

The meeting details suggest Mr Ward was “okay” with the construction of the interchange’s eastern roundabout being dependent on further development in the area.

A Roads and Maritime Services spokeswoman has confirmed that each roundabout would provide access for Dapto motorists travelling in one direction only.

“The western side of the roundabout for the northern, or Yallah, interchange for the Albion Park Rail Bypass will facilitate off and on ramps for motorists travelling north,” the spokeswoman said.

“Motorists travelling south from Dapto would not travel on the bypass until the eastern roundabout is built.”

It is understood Mr Ward may have concluded that one roundabout was sufficient to give Dapto residents access in both directions.

There is no funding for the eastern roundabout at the moment, and RMS said the traffic modelling does not support its immediate construction.
