A number of business cases evaluated by Infrastructure Australia have been publicly released, view all available business cases.
The business case is for a 27-kilometre four-lane grade-separated dual carriageway road at the outer edge of Bunbury. It would connect the Bussell Highway, north of Bunbury, to the Forrest Highway in the south.
This business case proposes an alternative freight access route to the Port of Albany. The project would involve a ring road around the urban areas of Albany, which aims to improve freight efficiency and help separate freight, local and tourist traffic within Albany.
The business case is for a new 16-kilometre motorway to connect the Western Sydney International Airport at Badgerys Creek with Sydney’s motorway network.
