Stage two of the Barwon Heads Road duplication would be funded with a $125 million commitment from the Liberal Party if it wins the November state election.
The 6km duplication between Marshall and Lower Duneed Roads would begin in 2024.
The 4km stage one duplication between Settlement and Reserve Roads is underway and will cost $365 million.
Stage one involves raising part of the road to help prevent flooding, building a bridge over the railway crossing at Marshall and intersection upgrades at Settlement Rd and Breakwater Rd.
The Labor government has yet to commit to funding the second stage of the road duplication.
This Liberal Party commitment will be delivered in partnership with the federal government, which previously committed $125 million towards the $250 million project.
Stage 2 works would begin after stage one is completed by late 2023.
Liberal Candidate for Bellarine Donnie Grigau said it was a much needed road upgrade that will benefit the Bellarine.
“The second stage of the Barwon Heads road duplication will make driving through the Armstrong Creek growth corridor easier and ultimately provide quicker travel times between Geelong and Barwon Heads for families and tourists,” he said.
Shadow Minister for Transport Infrastructure Matt Bach said stage two would create hundreds of local jobs during the construction period while Liberal candidate for South Barwon Andrew Katos said the road would mean better connections for local families who are facing increased travel times and congestion.
“Investing in this important project will mean a quicker and safer commutes for families in Armstrong Creek, Grovedale and Marshall.” Mr Katos said.
“These communities are growing fast and if we don’t invest for that growth now, they will be left behind.”
Labor candidate for Bellarine Alison Marchant had not responded to the Voice’s invitation for comment by the time it went to print.
