In 1917 the New Zealand government opened up Mangapurua Valley for settlement by servicemen returning from the World War I. Virgin forest was cleared and 35 farms were established. Initially the valley prospered but access remained a problem and following persistent requests for improved access by the residents the government agreed to erect a bridge across the Mangapurua Stream. The bridge was designed by the Public Works Department in October 1933. Construction of the bridge started in January 1935. Concrete was mixed by hand and the reinforcing steel was bent and cut on site. Construction was completed in June 1936. A swing bridge, built in 1919 and located c40 metres upstream, fell into disrepair from this time.
Economic hardship, inaccessibility and erosion resulted in farmers abandoning their farms. By 1942 only three families remained and they were forced to leave as the government closed the valley in May that year. The disappearing roads and fence lines, and the Mangapurua Bridge, are all that remain of this ill fated government settlement. The bridge is a destination for pedestrian traffic only.
In 1993 the Department of Conservation has been undertaking a concrete investigation costing in the vicinity of $10 000 and plan to spend $30 000 - $40 000 on concrete repairs in 1994. Rust has appeared in some places where the reinforcing steel has been exposed.

Why is this place significant?
Historic Significance
Historical Significance or Value Contrasting the overall success of the resettlement programme for World War I veterans, the Mangapurua Settlement is notorious as a failure. With its reinforced concrete construction, Mangapurua Bridge is very much an enduring symbol of this failed settlement. The failure of the settlement does not diminish the importance of the bridge but rather adds to its renown. Mangapurua Bridge is relatively well-known throughout the Wanganui region, and has been chosen as the dominant feature in the Whanganui National Park logo. Located within this national park and with native bush surrounds, the bridge reflects the change in attitude from using to conserving New Zealand's natural resources.
Physical Significance
ARCHITECTURAL QUALITY: Mangapurua Bridge is a Public Works Department bridge and is a typical example of its genre, that of the arched reinforced concrete bridge. Bridges such as this were built throughout New Zealand. TOWNSCAPE/LANDMARK VALUE: As a result of its scale and reinforced concrete construction, Mangapurua Bridge is the most significant man-made structure in Whanganui National Park. It is almost engulfed by its native bush surrounds and appears somewhat incongruous. Other man-made structures such as roads and fence lines are disappearing.
