Why is this place significant?
Historic Significance
Historical Significance or Value The Opawa River bridge was designed at a time of international experimentation in the use of reinforced concrete in such engineering structures, especially by Swiss, French and German engineers. The bowstring arch design in concrete enjoyed a period of popularity in New Zealand through to the 1930s. The bridge is still an important part of the South Island State Highway 1.
Physical Significance
ARCHITECTURAL QUALITY: The Opawa River bridge was one of the first bowstring arch bridges in reinforced concrete to be built in New Zealand. Despite the somewhat heavy nature of its construction, the low bold arches in sequence give it an overall rhythmic architectural elegance, although it does lack the refinement of later bowstring arch bridges in New Zealand, such as the former Fitzherbert Bridge (Palmerston North 1935) and the Fairfield Bridge (Hamilton 1936). TOWNSCAPE/LANDMARK VALUE: The bridge is a well-known structure spanning the Ōpaoa River and is a significant local landmark.

ARCHITECTURAL DESCRIPTION: The bridge which carries State Highway 1 over the Ōpaoa River at Blenheim, has a total length of 170 metres. It has eight bow-string arch trusses of equal length. Each span has eight vertical hangers and diagonal reinforcing members, supporting the heavier lower chords, which carry the roadway. Heavy posts form the ends of each truss, which are supported on reinforced concrete piers, each having three converging flanges with their upstream faces formed at diagonals to assist water flow. A footpath is cantilevered on the downstream side of the bridge and horizontal iron bars have been placed between the truss hangers to form a barrier between the footpath and the roadway. MODIFICATIONS: No significant modifications have been made.
