These are a series of wooden bridges, interspersed with embankments on the original alignment of the Wodonga to Cudgewa Railway. The bridges were abandoned in the 1950s when a new, steel span bridge was constructed further south, after the Hume Dam was raised to hold more water.
That newer bridge was deconstructed in later years after the line was closed and the ROW converted into a rail trail. The steel spans were removed and stored beside the old line at Bandiana, some spans went to the Yarrawonga to Mulwala line, some to Dartmoor in South Western Victoria where they are stored pending re-use, and some to repair the Avon River Bridge in Gippsland. The remaining 13 spans are still at Bandiana. The spans that went to the Avon River were not required, as the entire bridge was replaced in the early 2020s.
From time to time, as the water level in Lake Hume gets low, the eight bridge remains become visible. Brad Mull shot a really good flyover of the remains some time ago during a low water period. I am indebted to Brad for the use of this footage, it is shown below.
And back again in the reverse direction:
