Dunmore Bridge - Historic Allan Truss Bridge over the Patterson River - Woodville, Hunter Valley, NSW

"Completed in 1899, the Dunmore bridge is a representative example of an Allan truss road bridge, and is one of three surviving overhead braced timber truss road bridges in NSW. The bridge also has a lift span to allow river traffic under it, which is a rare feature that also contains much technical significance and information about engineering technology of the late 19th century. Most of its engineering details are intact, and the bridge is in good condition.
As a timber truss road bridge, it has strong associations with the expansion of the road network and economic activity throughout NSW, and Percy Allan, the designer of this type of truss.

Allan trusses were third in the five-stage design evolution of NSW timber truss bridges, and were a major improvement over the McDonald trusses which preceded them. Allan trusses were 20% cheaper to build than Mc Donald trusses, could carry 50% more load, and were easier to maintain.

The people who live in the area around the bridge (Woodville and the Hunter region) value the bridge highly, and as such it has social significance.

Dunmore Bridge is located in the Hunter region, which has 15 historic bridges each constructed before 1905, and it gains heritage significance from its proximity to the high concentration of other historic bridges in the area.

In 1998 there were 38 surviving Allan trusses in NSW of the 105 built, and 82 timber truss road

bridges survive from the over 400 built.

The Dunmore bridge is a rare and representative example of Allan timber truss road bridges, and is assessed as being Nationally significant, primarily on the basis of its technical and historical significance." Read More HERE
