This list documents historical bridges located in New South Wales, Australia. Road, rail and pedestrian bridges are listed. Generally bridges built before WWII (1939) have been included in this list.

Historical context[edit]

Bridge construction in New South Wales starts with the needs of the first settlers and continues through to the present day with advanced bridge design. The infant colony had limited expertise and limited materials, as time passed techniques and materials were developed that allowed greater spans to be crossed and therefore expansion of the colony into otherwise inaccessible areas.

The NSW Public Works Department was under pressure from a cash strapped government to produce as much road and bridge work for as little cost as possible.[1] The cheapest bridge was the timber truss which could be built with local timber.

All bridges are unique, in the end the bridge that is built depends on the technology, expertise, materials and need to gain access to an area.

At the time of early settlement (1788 onwards) NSW was very isolated from the technological advances being developed in Europe and North America. Materials such as cast iron were unavailable to early colonial NSW bridge builders. NSW bridge builders had to rely on their own resourcefulness, bred of isolation, distance and the unique environment.

Australia's unusual environment results in unusual, and extreme river flows, almost no flow for some parts of the year and in extreme floods in other seasons. Early settlers sometimes built rudimentary structures in low rainfall seasons only to see the structures washed away in high rainfall times. With little funds available to the authorities the trend was to build light structures that could not stand the test of high and fast flowing water.

In solving these problems, colonial NSW embraced the innovations produced by others and adapted them successfully to the unique situations presented. There are examples of some very fine 19th-century bridge engineering provided for the railway expansion, conceived mainly by British engineers working in the then isolation of the Australian inland, and we have well-developed examples of many of the newer European techniques such as cable-stayed bridges.

Australia developed around coastal communities with rudimentary road systems to inland settlements. The early years saw early bridge technology limited very much to the 18th century European technology of masonry arches and cast iron, the latter still in its infancy and not produced to any great extent in New South Wales.

NSW at the time of early settlement had an abundance of convict labour and had a need for rapid construction. In a country heavily timbered this led to basic timber structure bridges but as the Colony gained stability the government looked towards more permanent structures and, as the skills for quarrying and stone dressing became available, masonry bridges began to be designed and built. As all metal materials had to be imported, iron bridges were rarely appropriate and were in any case still too novel for colonial application. Iron bridges were only used for major crossings on important corridors.[2]

Timber truss bridges, and timber bridges generally were so common that NSW was known to travellers as the "timber bridge state".[1]

The following list illustrates the development of New South Wales bridge construction techniques. The list commences from the earlier constructions through to the later developments.

Allan type truss[edit]

The Allan truss bridge is named after Percy Allan, a famous Australian architect and engineer who designed the bridge type. His design consists of vertical and diagonal arrangements of trusses which are were originally composed of steel. Today many of the bridges based on Percy Allan’s design are composed of iron bark or even timber to reduce the cost.

The Hampden Bridge in New South Wales Australia was the first bridge to be built on Percy Allan’s design[19]

Dare type truss[edit]

Harvey Dare was a leading engineer in the Public Works Department, and a prominent figure in early 20th century NSW. He was a designer of bridges and he developed the Dare Truss which was similar to the Allan Truss but contained improvements which make them stronger and easier to maintain. This engineering enhancement represents a significant evolution of the design of timber truss bridges, and gives Dare trusses some technical significance. Dare Trusses were the fifth of the five stages of evolution of timber truss road bridges in NSW.[1]

In 1998 there were 27 surviving Dare trusses in NSW of the 40 built, and 82 timber truss road bridges survive from the over 400 built.[1]
