Main Roads Act

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.

Extent of Operations

We are one of the largest geographically spread road agencies in the world, responsible for more than 18,500 kilometres of road spread over 2.5 million square kilometres. Our role is to plan, build and maintain Western Australia’s State Road Network valued at just over $46 billion. We work closely with our portfolio partners, Department of Transport and 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. Last year we engaged directly with over 4,000 suppliers and made in the order of $1.785B in payments. Of our suppliers, 190 were government agencies (State or Local) and 7 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.
