Facts and Figures

Our Roads

We are currently responsible for Western Australia‚Äôs main road network.

You can find out which roads we are specifically responsible for by following one of the links below:


Road Classification

There are several road classification systems in use in Western Australia. Each has a different purpose. The Administrative Classification system determines which sphere of government has management responsibility for public roads (Main Roads or local government).

Following consultation with WALGA and local government, by way of a jointly represented working group, we have released updated criteria for identifying administrative responsibility of roads within built up areas (usually State or local government). These amended criteria have been posted on the WALGA website for member comment. Following consideration of any feedback from WALGA, the new criteria will be implemented and PART 2 - GUIDELINES FOR DETERMINING AND ASSIGNING RESPONSIBILITY FOR ROADS IN WESTERN AUSTRALIA - Administrative Classification of Public Roads (urban section) will be updated.

Information about administrative classification policy and assessment criteria is available through the following links:

It covers:
