Bridge to Nowhere: New Zealand's Mangapurua Track reopens with seven new bridges

A concrete bridge deep in the forest with no road leading to it any more: the Bridge to Nowhere in Whanganui National Park on New Zealand's North Island is one of the country's most striking places. Since Saturday, Oct. 24, 2026, the Mangapurua Track, which leads to it, has been open to cyclists again after its winter closure. As New Zealand's Department of Conservation (DOC) announced on Oct. 23, seven new bridges were installed ahead of the season. The old narrow crossings were hard to cross with bikes and had reached the end of their useful lives; the new ones are wider. "I first rode the Mangapurua in 2015, and this is the best opening condition I've seen it in since then," said Lynley Twyman, general manager of the Ngā Ara Tūhono Charitable Trust, according to DOC.

According to DOC, the bridges are lightweight truss structures built offsite and flown into the remote area fully constructed. "It's something we're doing more often, flying in strong, lightweight truss bridges which have been built offsite," said DOC project manager Louise Brown. The work is part of a programme of 15 new bridges and boardwalks across the Mangapurua and neighbouring Kaiwhakauka tracks; Kaiwhakauka upgrades are scheduled for November and December 2026, with bypasses and possible delays. The Mangapurua Track is part of the Mountains to Sea – Ngā Ara Tūhono Great Ride, which, according to Tourism New Zealand, runs through Tongariro and Whanganui national parks. It is rated Grade 3 (intermediate): DOC warns of exposed sections, steep drop-offs and papa surfaces that become slippery when wet.

Behind the bridge lies a story of failure. After World War I, according to the government history site NZHistory, 40 families of returned soldiers took up land in the Mangapurua Valley, farms of about 450 hectares each cleared from steep bush. By the time the concrete bridge was handed over in June 1936, most had left. In 1942 heavy rain wrecked the road, the government refused to repair it, and in May it ordered the last three families out. The forest reclaimed the valley; in 1986 it was added to Whanganui National Park, which covers 742 km² according to International Parks and, according to DOC, protects one of the largest remaining tracts of lowland forest on the North Island. The roughly 36-kilometre route ends at the Whanganui River, according to Tourism New Zealand, from where travellers continue by jet boat or kayak to Pipiriki.
