The 8th equal highest viaduct in New Zealand is the 71.6 m high, 160 m long Waikoau viaduct between Napier and Wairoa. It is of steel girder construction with a 76 m long central span weighing 300 tonnes, the third equal longest span of any railway bridge in New Zealand. Here is a 54 kb picture of the nearby 65.5 m high Matahorua viaduct which has an identical central span.
