B-triple road network access
Establishing a national B-triple network is a key freight-efficiency initiative under the Council of Australian Governments (COAG).
B-triples have been successfully operating in Queensland since 1996 and have been proven as a freight-efficient heavy vehicle combination that contributes to regional development, improving road safety and reducing adverse environmental impacts through fewer trips.
Typically, one B-triple has equivalent carrying capacity of two semi-trailers.
Queensland provides an extensive road network for B-triple access, with most areas west of the Great Dividing Range approved for access, covering approximately 21,700 km of the arterial network.
A B-triple network map is available that outlines Queensland's approved B-triple network.
Work is currently underway to extend existing B-triple network access to key freight hubs, such as Townsville and Gladstone, where this can be safely achieved.
