This manual covers the planning, design, construction, maintenance and operation of road drainage infrastructure. It provides the technical reference required for all aspects of hydraulic, road drainage, erosion, environmental and sediment control throughout Queensland.

The Department of Transport and Main Roads has generally agreed to adopt the guidance published in Austroads' Guides to Road Design series as part of national harmonisation. While the Road Drainage Manual remains the primary document, it references and adopts criteria and methodology as published in the Austroads Guide to Road Design, Parts 5, 5A and 5B.

An Alignment Map is provided for easy identification of information to be found in the Austroads Guide.
