The landscape at Gundagai is dominated by four bridges spanning the Murrumbidgee flats: the historic Prince Alfred Bridge, the timber Railway Bridge, and now the dual Sheahan bridges of the Hume Highway.
The timber viaducts are wonderful examples of early engineering solutions to crossing a major flood plain. Their national significance is recognised with listing by the National Trust. They are a spectacular latticework of wooden trusses, spanning the flood plains and River.
The Railway Bridge was completed in 1902. The viaduct is 819.4m long.
