Labor could consider adding the Yallah interchange to the Albion Park Rail bypass if it wins the March election.
The Yallah interchange would provide southbound access to the bypass for residents in the growing West Dapto area.
However, Roads and Maritime Services has opted not to include it in the current plans for the bypass.
Instead, motorists heading south from Dapto will still have to use the existing Princes Highway through Albion Park Rail.
Those motorists will be able to use the bypass when heading north as there will be an off-ramp linking it to the Princes Highway.
Keira MP and Labor's treasury spokesman Ryan Park said he was aware of the issues West Dapto residents had when it came to the Yallah interchange.

He said the interchange - or other possible solutions - were on Labor's agenda should it win government in 10 days' time.
"If we win government we will certainly be examining the issues surrounding access to the bypass for Dapto residents," Mr Park said.
More broadly, Mr Park said Labor was committed to continuing construction of the bypass; major work began earlier this year.
“Labor is committed to ensuring the completion of the Albion Park Rail Bypass and will match the $630 million funding for the project," Mr Park said.
"[Shellharbour MP] Anna Watson has been a vocal advocate for this project for many years."
Last year RMS formally announced the Yallah interchange would not feature in the bypass design.
Traffic modelling was carried out, which took into account growth in residential developments at Yallah and West Dapto.
"This indicated that the interchange is not required until there is a substantial increase in traffic," a spokesman said.
The spokesman said traffic volumes along the Princes Highway were expected to by 65 per cent once the bypass was constructed.
