17th Engineering Heritage Conference: Canberra 100 - Building the Capital, Building the Nation
Engineers Australia, Barton, Australian Capital Territory, 2013, pp. 146-154

The bridge over the Murrumbidgee River at Tharwa, opened in 1895, consists of four spans of timber Allan Trusses, each 27.4m (90ft) span, flanked by approach spans, originally of timber, but later of reinforced concrete and steel. The bridge is picturesquely located in the rolling hills of the Murrumbidgee Valley with a backdrop of Mt Tennant brooding above Tharwa. It is unique in its heritage value to the local community and to the Nation. The history of the site and the bridge is given, the development and contribution by the authors to the Conservation Management Plan is outlined, the rationale for the heritage sensitive strengthening of the trusses is explained and the restoration and conservation works during 2008 to 2011 is briefly described. The arrangements for on-going maintenance are also briefly described.
