Our Minister, Legislation, Role and OperationsDownload this section (1.3 MB)
Honourable Rita Saffioti MLA Minister for Transport; Planning; Lands
The Main Roads Act 1930 (WA), as last amended in 1996, establishes the Commissioner of Main Roads as a corporate body and sets out the powers and duties of the office.
Our role is to plan, build, maintain and operate Western Australia’s State Road Network valued at more than $47 billion. We work closely with our portfolio partners, the Department of Transport and the Public Transport Authority as well as local government to support the needs of all road users across the state by providing an integrated world-class road transport network.
Extent of Operations
We are one of the most geographically dispersed road agencies in the world, responsible for more than 18,500 kilometres of road spread over 2.5 million square kilometres.
Last year we engaged directly with more than 4,500 suppliers and made in the order of $1.962 billion in payments. Of our suppliers, 158 were state or local government agencies and 16 were research bodies or universities. The remainder are classified as contractors, consultants or suppliers and are predominately from the Western Australian economy. Our indirect supply chain is again more extensive with our construction projects engaging with multiple sub-contractors and suppliers.
