Over the last decade almost 60 per cent of population growth has occurred in Melbourne’s outer suburbs, putting pressure on Melbourne’s outer suburban roads.

The OSARs Western Package will transform the outer western suburban arterial road network by boosting capacity and significantly increasing road pavement conditions with a program of road and interchange upgrades. The project includes almost 30 kilometres of lane duplication and over 700 lane kilometres of road rehabilitation and maintenance over a 20 years period.

The Western Package is being procured as an “availability payment” style PPP with the Invitation for Expression of Interest currently in the market.

The capital works package includes:  

Dunnings Road and Palmers Road upgrade, Point Cook Road to Princes Freeway, Point Cook;

  • Derrimut Road upgrade, Sayers Road to Dohertys Road, Tarneit;
