Design loads for Australian bridges were last reviewed in the 1970s (see IRRD 231221), resulting in adoption of the T44 design vehicle. Since that time there have been significant increases in legal load limits together with major changes in vehicle configurations, all aiming at improving transport efficiency. This paper describes a project aiming at developing a revised bridge loading standard for the design and construction of Australian bridges over the next 25 years. The project was approached from a road user perspective, and aimed to look well beyond recent incremental increases in legal loading to try to find an end point in the evolution of the Australian general freight vehicle. This paper also presents a summary of the new bridge design traffic live load and some of the underlying investigations and theories that formed the basis for this loading. Finally some comments are made about potential implications of the continued implementation of increased loads on freight vehicles.
