A southern link over the Melbourne-Geelong rail line to the Princes Freeway has been identified as a “crucial component of the Wyndham West road network”.

The rail overpass and a number of east-west arterial road connections have been highlighted in one of two Wyndham council draft reports which outline future road infrastructure needs in two of the area’s growth regions.

The reports – although described as “not binding” and subject to change – were prepared for the council to consult with landowners and developers on what developer contributions will be needed to fund projects in Wyndham North and Wyndham West.

The Wyndham West report states the overpass, classified as state infrastructure, is to be: “funded and constructed by the state government at a cost which could approach $30 to $40 million”.

Cr Henry Barlow said the council was in talks with the state government about funding the overpass.

He said when completed, the overpass would give residents access to the freeway without having to travel through the centre of Werribee.

The council’s short-term focus in Wyndham West would be on delivering Armstrong-Ison Road, according to the report.

The Wyndham North draft report stated the focus would continue to be on delivering Leakes Road, including the Tarneit Road and Leakes Road intersection, and duplicating Leakes Road east of the intersection to Forsyth Road.

The report stated developer contributions of $19.2 million for the year ending June 30, 2017, meant that within the next one to four years planning could also begin on additional projects including the Boundary Road and Derrimut Road intersection and Dohertys Road bridge over Skeleton Creek.

Wyndham North precinct structure plans (PSPs) for areas known as Oakbank, Truganina, Riverdale and Tarneit North.

Wyndham West includes PSPs for Alfred Road, Black Forest Road, Ballan Road, Westbrook, Quandong, Black Forest Road North and Bayview.

Both areas are expected to be home to thousands of future residents.
