The place is the only remaining bridge in Western Australia that contains vertical wing sheeting.
The place is rare as a small-scale timber bridge in Western Australia.
The place is important in relation to the development of transport routes and facilities in the Kojonup district.
□ Round timber stringers over driven timber piles. □ Several unusual features including vertical wing sheeting. □ Four spans of 6m □ Length 24m □ Width between kerbs 4.3m
‘The first substantial road bridge in Western Australia at Drummonds crossing was built in 1835. Only a handful of other road bridges were completed in the period up to 1850 when the first shiploads of convicts arrived.’ ‘The arrival of the first contingent of Royal engineers, in December 1851. meant that the convict labor could be adequately supervised, and construction of public works (including road bridges) was greatly accelerated. The effect of using this small group of engineers combined with the ready availability of good bridge timber was that simple standardized structures were usually built.’ ‘Significant detail changes over time have included the general change from round timber full caps over the piles at each pier, to the more easily maintained sawn timber halfcap system. Early bridges rarely used corbels but the use of these to support stringers over piers was almost universal by the 1890s. Sawn Jarrah stringers were normal between the 1890s and the late 1920’s (Kalgan River Road bridge was built in the style in 1907) when round stringers were adopted for their greater strength. A different superstructure system – that of supporting longitudinal decking over transverse bearers, on a wider spaced round stringer was adopted for a period during and immediately following World War II. Many other minor details are characteristics of particular timer periods.’
