The iconic Te Rewa Rewa Bridge

New Plymouth's Te Rewa Rewa pedestrian and cycle bridge provides a spectacular illustration of the capacity of engineering to combine utility with fine art. The tied arch bridge with a clear span of almost 70 metres is part of the extension of the city's award-winning coastal walkway. Spanning the Waiwakairo River, its iconic form represents the sacred relationship between the land, sea and wind with the Ngati Tawhirikura tribe.
