Artist's Description
The heritage listed timber truss railway bridge comprises 77 timber trusses based on the American Howe truss concept. Each truss is approximately 35-40 feet long and the single rail track is on top of the bridge. These trusses are supported well above the flood plain of the Murrumbidgee River on tall timber trestles.
Locally sourced materials were the preferred choice in the era when the railways expanded rapidly in Australia. Australian eucalypt trees, and in particular the “Ironbark” variety possess great strength and stiffness. Solid timber members are used in the trusses and trestle supports to carry compression loads and in the deck where bending resistance is required. Iron rods are used to carry tension forces. Careful checking of the timber components means that most of the forces are transferred by direct contact.

In "my former life" as a University Professor teaching structural engineering in Australia and before that in Canada I started collecting 35mm slides of a technical nature (buildings, bridges, concrete, steel, timber etc.) that I could use in my teaching. In this role I was instrumental in the early 1990s to start collecting technical images of all aspects of structures and to start putting these images into a more pictorial "multimedia" orientated teaching environment. Much later, after retiring from Academia, I moved from 35mm slides to digital cameras. A great deal later (about 2010) I invested in a Nikon D80...
