Our Minister, Legislation, Role and OperationsDownload this section (2.8 MB)
Honourable Rita Saffioti MLA Minister for Transport
The Main Roads Act 1930, as amended, 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 $48 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 5,400 suppliers and made in the order of $2.174 billion in payments. Of our suppliers, 292 were state or local government agencies and 32 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.
Main Roads operates from eight regional locations throughout the state.
