Description

The Tauranga Bridge, also known as the Tauranga Track Bridge, is one of only two remaining early New Zealand “harp” or cable stayed bridges. The bridge was constructed as a means of accessing farms over the Waioeka River from the main road north to Opotiki. These farms had been established by the government for servicemen returning from World War One.

This timber bridge with Australian hardwood trestle towers, and concrete piers, was designed between 1916 and 1918 by the Public Works Department (PWD) and built in 1921. The single span is 57.8 metres (m) long. The 3 m wide deck is supported by 6 transoms at 6 points between the towers, and each transom is in turn supported by a steel cable that is continuous between the anchor sets on each side of the river.


The PWD engineers who designed the bridge adapted the use of steel rope to the English multi-rod system and combined some good kiwi ingenuity with an American initiative in the development of steel rope suspension bridge construction.

The farms that the bridge provided access to were abandoned by the 1960s. By the 1990s the bridge had become isolated because of the state of the roads leading up to it, and as such was degraded to the point of being unusable. The Department of Conservation (DoC) manages the Waioeka Gorge Scenic Reserve, and in February 1992 Ron Campbell of Opotiki brought to their attention the urgent need to stabilise the true right tower. Ron then completed this work, which undoubtedly saved the bridge from collapse. Then in 1994 further conservation works were completed by DoC and the bridge was formally reopened to pedestrian traffic on the 11th March 1995.
