Bethanga Bridge
The Bethanga Bridge is a long, nine-span, riveted-steel, variable depth, Pratt Truss road bridge of nine principal spans of 82 metres and a total length of 752 metres over the flooded valley of the Murray River, now part of Hume Reservoir.
The bridge dates from 1927-1930 when the Hume Weir was completed and the backed-up waters inundated this section of the river and consequently cut off the old low level bridge over the Murray.
The State Rivers and Water Supply Commission of Victoria and the New South Wales Department of Public Works were responsible for the construction works for the Hume Weir under the River Murray Waters Agreement. It is apparent that a similar joint arrangement was made for construction of the Bethanga Bridge as part of the Hume Weir works.
Charles Ruwolt Pty Ltd of Melbourne fabricated the truss spans.

| Heritage Significance | Bethanga Bridge is an example of Pratt Truss design displaying the main characteristics at a scale that demonstrates the effectiveness of the design over long spans; and of its repetition to create a bridge of considerable overall length. The use of compound riveted sections in the steel trusses and the refined details of connections and bearings are representative of bridges of this age (the Sydney Harbour Bridge has similar detailing). These bridges represent the final level of refinement in steel truss bridges. |
