|Cobram Barooga Bridge is a timber truss, lift-span bridge generally two lanes wide, across the Murray River at Barooga. The main axis of the bridge is east-west.
There are three main spans including one lift span supported on cast iron piers. On the eastern (NSW) approach there are six approach spans and on the western (Victorian)side there are three. The approach spans are of steel and timber girder construction on timber and steel trestle piers. The approach spans have a timber deck. The main spans have a plywood deck.
The two main truss spans are of composite steel and timber construction, (approximately 31.7m spans).
The trusses have timber top chords and struts with steel bottom chords and diagonals. The trusses support steel cross girders and timber stringers. The cross girders are tapered.
The lift span superstructure is of steel lattice construction with a span of 18m. The deck narrows across the lift span and is reduced to one lane. The lift span beams are riveted girders. The lift span counterweight and lift membranes are still in place.
The main piers are twin cylindrical cast iron piers.
The approach spans on both ends range from approximately 9.1m to 11m spans and have six girders with the outside truss timber and the inside four steel in each span supporting the deck. The beams sit on steel and timber trestle piers.
The timber top chords on the trusses have steel capping.
There is a footway on the northern side with a timber guard rail.
The bridge has a clearance over normal water level of 7.9m with the lift span closed, and 14.3m with the lift span open.
Rare DeBurgh timber truss bridge, with metal Pratt lift-span is one of only two of its type in Australia. The DeBurgh truss is one of a group of internationally notable timber truss designs developed for Australian hardwoods by NSW engineers. The Cobram Bridge is by far the largest of the nationally significant group of five timber bridges that remain on the Murray. Seen as a symbol of Federation, it was the only Murray bridge funded entirely by Victoria. Its lift span provides direct evidence of the famous Murray River paddle steamer era.
