News | Rakaia Gorge Re-deck
The Rakaia Gorge Bridge in Canterbury needed an upgrade because of its poor condition and continuous maintenance. PNGFP's NiuDeck from PNG Forest Products was the solution for its strength, lightweight and proven track record as a road decking system.
Constructed between 1880 and 1882, the Rakaia Gorge Bridge is a wrought iron, 55m long single span, single vehicle lane, mid-Canterbury bridge important in the local road network asset because it facilitates access to the surrounding farms and towns, as well as Mount Hutt ski field. Its deck truss has a unique design in relation to any other New Zealand bridge, and this dynamic looking bridge's design and construction involved several of the country's high profile late 19th century Public Works Department (PWD) engineers.
