Prospect Highway upgrade

The NSW Government is planning for the future needs of Western Sydney. To date, it has provided $9.6 million to plan for a potential future 3.6km upgrade of the Prospect Highway, between Reservoir Road at Prospect and St Martins Crescent at Blacktown, to reduce congestion and meet future traffic demand on this road corridor.
