Commissioned by the Rangitikei County Council in 1922, the Springvale Suspension Bridge, as it has became known locally, provided an essential and safe crossing of the flood-prone Rangitikei River. In a largely agricultural region this river is a valuable resource however it also represented a challenge to early settlers; early records show that a flood in 1897 destroyed all six bridges in existence at the time.

To cross this river is an essential and integral part of community life, both past and present. At one time it meant traversing the 'prehistoric ford', located directly below the suspension bridge. In 1903 a temporary suspension bridge was shifted from Kuripapango to a location near the site of the current suspension bridge, however for foot traffic only. The demand for a traffic bridge was high, as recorded in the Taihape Daily Times on the 9th of October, 1916, which expressed 'That bridge is now needed so urgently to complete road communication with the block of land given for Maori Settlement and the great Mangaohane block of land given for Maori'.

Maori movement in this area has a long history. The bridge crosses the Rangitikei River at the same spot as did generations of Maori trekking the 'Inland Patea' route. This route is an old Maori trail from the East Coast to the centre of the North Island. After another significant flood in 1958, one of the very few Moa hunting sites in the North Island was revealed not far upriver.

European history dates from the mid-nineteenth century when Reverend Richard Taylor and the missionary William Colenso both travelled the historic route, spreading their Christian beliefs. The first European sheep farm was established by Captain Azim Birch and his brother William when they bought the land between the Moawhango and Rangitikei Rivers in 1867. They named the area Erehwon, spelling 'nowhere' backwards. Later renamed Erewhon riding, this area went on to become a well-known example of the late nineteenth century post World War One settler programmes, in which large tracts of marginal land were opened up for development.

The erection of a traffic bridge was therefore vital to expanding agriculture in the Rangitikei district at this time. It was needed to facilitate easier access to the farms inland and for the movement of stock and wool to the port of Napier. It also would be valuable to the social life of the communities, providing a link to the rest of the country and thus opportunities to enjoy travel as a leisure pursuit. For the people in this area the bridge represented a chance to strengthen ties amongst communities and increase social networks.

The Springvale Suspension Bridge was designed by S.A.R. Mair (Sydney), the Engineer of the Rangitikei County Council from 1899 to 1947. Tenders were called for and by November 1923 one was accepted from William Salt, a bridge contractor from Wanganui. Salt went on to become a successful bridge designer; despite his short career he built many major river crossings in the Rangitikei, Wanganui and Waitotara regions. The Springvale Suspension Bridge was his major achievement, and may be the only bridge he built that is extant.

Construction was completed in early 1925, and cost £4473 13s 6d. The Erewhon Bridge, as it was then unofficially known, was opened in early April in time for the Easter holidays. A 61 metre long structure of reinforced concrete, steel and Australian Hardwood decking, it is visually inspiring and an impressive engineering achievement. The seven metre tapered concrete towers are anchored by large concrete blocks below ground level. The bridge utilises 140mm cables made of plough steel wire with a breaking load of 12 tonnes. Diagonal sway bracing can be seen from beneath the bridge, with sway cable anchoring the bridge to the banks.

Due to an increasing amount of vehicles using the bridge over a 45 year period, repairs were becoming more frequent and it became apparent that a new bridge would have to be built to accommodate the rising traffic numbers. Thus in 1970 the Callender-Hamilton Bridge was constructed less than 50 meters away. Threatened with demolition, R.A.L. Batley (Tony) of Moawhango advocated for the preservation of the bridge through his recommendation in 1974 that it be bought by the New Zealand Historic Places Trust.

The Springvale Suspension Bridge is registered as a Category II Historic Place in recognition of its historical and social value and its significant technological design. Once a common sight in New Zealand, today there are only a few of these bridges that remain in working order and have a viable future. Its presence is testament to the bridge's durability and lasting significance. It is an iconic achievement of engineering of the era, exhibiting the pioneering spirit of overcoming the challenges of the terrain and achieving the expansion of settlement into the 'Inland Patea' and indeed the interior of the country.
