Statement of significance:

This bridge is a McDonald timber truss road bridge. Timber truss road bridges were extensively used in New South Wales because of the high quality of local hardwoods and the shortage of steel during the early decades of settlement of the state. The timber truss was highly developed for bridges in New South Wales, perhaps more so than anywhere else in the world at that time. The McDonald truss is a significant evolutionary link in the development of timber road bridges in New South Wales and has three standard span lengths, 65'/19.96m, 75'/22.86m and 90'27.43m . At March 1998 there were seven McDonald truss road bridges remaining in New South Wales, McKanes Falls Bridge being one of two with a 27.43m span and one of two in a double span configuration. The bridge has been assessed as having State significance.

Description

Designer/Maker: John McDonald, NSW Engineer for Bridges
Builder/Maker: NSW Public Works
Construction years: 1892-1893
Physical description: The bridge consists of two 90' ( 27.43m ) truss spans supported at each end by sandstone masonry abutments. The centre pier was built as stone but replaced with a reinforced concrete pier in the 1980,s following flood damage. The bridge with a 4.57m (15') between kerbs at its narrowest. There is no footway. The deck is made up of lateral timber cross girders supporting longitudinal timber decking. The cross girders are bearing on the bottom chords of the trusses. The substructure consists of two sandstone abutments and a central concrete pier.

History

Historical notes: The design of the McDonald Truss was greatly influenced by the needs of the time. During the period 1865-1885, the Public Works Department was attempting to tap the resources of inland Australia and to redirect the line of trade from Melbourne to Sydney. To achieve this most funds were directed at the railways. As more people were moving to the rural areas it was necessary to link farms and towns to nearby railheads, with consequent road and bridge requirements. The McDonald Truss was designed by John A McDonald M.I.C.E. and was the answer to the need for more bridges, the technical faults of the old PWD design and limited funds.
It is most probable that McKanes Falls, McKanes Crossing and McKanes Bridge are named after Archibald McKane. He was born in Edinburgh in 1807 and was trained as a joiner and ploughwright. He was convicted of cattle stealing in 1830 and transported to Australia for 7 years. He was sentenced to another 7 years for larceny in 1833. He was appointed as overseer of carpenters in the 1830s. He was involved in expeditions with Mitchell and was commended for his duties as a carpenter. He was granted his certificate of freedom in 1844.

The road on which the bridge sits was built in the late 1870s to connect Bowenfels and Hampton. With the increase in road use in the early 1890s due to tourism (Jenolan Caves) but mainly farm production, especially wool, the road was upgraded and the bridge was built in 1893.

Tenders were called to erect a bridge over Cox's River in September 1891 and was under construction by 1892. The bridge was constructed to shorten the distance for traffic going from Bowenfels to Lowther, Hampton and Jenolan Falls. The earlier route had run via Hartley.

Assessment of significance

SHR Criteria a)
[Historical significance]
McDonald truss bridges have historical significance because timber truss bridges were developed and refined in Australia to achieve the highest level of timber bridge construction for the time of their design and the McDonald truss is an important recognisable design in the evolution of timber truss bridges in NSW. The bridge also has a historical link with the evolution of the local community. The probable association with Archibald McKane and his involvement with Mitchell's third expedition also lends some significance to the crossing itself. McKanes bridge is a relic of the NSW government's policies of the late nineteenth century which focused on the provision of land areas to facilitate an increase in production and trade throughout the state. Is associated with John A McDonald, designer of the McDonald Truss and a significant figure in the area of bridge design and construction in NSW.
SHR Criteria c)
[Aesthetic significance]
McDonald truss bridges have aesthetic significance because they are evocative of Australian methods of bridge construction, in their materials, scale and configuration they reflect and express nineteenth century technologies and experiences and for the time of their design and construction they demonstrate the best quality design available. The dark green painting and the valley setting complement the surrounding rural environment. McKanes Bridge is an excellent example of a twin span McDonald Truss type bridge The scale of the structure, the natural timber and other materials allow the bridge to meld with the surrounding landscape.
SHR Criteria d)
[Social significance]
McDonald truss bridges have social significance because their size and location contribute directly to the local area and they are a strong element in the local environment. McKanes Bridge is located in farming country and is isolated, with few residents nearby. For these reasons there is little contemporary community association. However, the bridge forms part of local school bus routes and consequently is well known to the children of the wider community. The bridge has been an important feature of one of the old routes to the Jenolan caves tourist area since its construction in 1893. Built tp provide better access for traffic from Bowenfels to Lowther, Hampton and Jenolan Falls, it played a significant role for those people living, working and holidaying in the surrounding area.
SHR Criteria f)
[Rarity]
One of six remaining McDonald truss bridges, one of two 90' span bridges. One of very few timber truss bridges remaining in the Lithgow area. The only surviving example of a twin span McDonald Truss road bridge in NSW and one of only five surviving in NSW and still in use.
SHR Criteria g)
[Representativeness]
Representative example of a two span, 90' McDonald truss bridge. Representative of the first truss bridge design which can be considered uniquely Australian due to its local design and use of native timbers. Is an example of the design which led to a rapid expansion in bridge construction throughout NSW and an excellent example of a twin span McDonald Truss in in good condition and easily accessible
Integrity/Intactness: Elements of truss true to original design although most or all of the timbers have been replaced as part of routine maintenance as with other parts of the bridge. The Central stone pier replaced with concrete pier.
