A number of business cases evaluated by Infrastructure Australia have been publically released, view all available business cases.
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 to upgrade the Prospect Highway between Reservoir Road at Prospect and 200 metres north of St Martins Crescent, Blacktown (approximately 3.6 kilometres).
The business case is to build a new Armadale Road Bridge over the Kwinana Freeway, which would connect North Lake Road to Armadale Road in the Cockburn Central area. It aims to resolve current bottlenecks, improve travel times, and improve amenity and liveability within the area.
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.
The business case is for removing six level crossings on the inner Armadale Line. The project aims to improve safety and reduce congestion at the level crossings, as well as improving station precincts and public open space.
The business case is to extend the Armadale Line approximately eight kilometres south to Byford. This is to support and provide public transport access to the high-growth suburb of Byford.
The business case was accepted for Infrastructure Australia's evaluation on 14 July 2020.
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.
