Percy Burn Viaduct is located in the far south of South Island New Zealand. It is supposedly the largest surviving wooden viaduct in the world. A former wooden tramway, it is now a pedestrian bridge and the most popular feature of the Tuatapere and Hump Ridge Track. Logging companies account for a large portion of New Zealand's native timber. The Marlborough Timber Company, one of the country's largest forestry firms, was looking for new woodland areas to harvest and succeeded in securing the logging rights to an inhospitable and difficult-to-access timber area near Te Waewae Bay in the southwest corner of the island. The main timber was milled rimu.[ 1]

Access was originally only available by ship, and a wharf and settlement were built at Port Craig, but 25 kilometers .[ 3][[5] From April 2014 the bridge was closed and the restoration work had not yet started. It was expected to reopen in 2018.[ 6] The viaduct reopened in late 2018.[ 7]
