Building the Grafton bridge (1 o 3)

Building the Grafton bridge

The Grafton bridge, which spans Grafton gully in Auckland, was opened in 1910. It was then the largest reinforced concrete arch in the world. Building the concrete arch was a huge undertaking, using 943 cubic metres of West Australian jarrah and Oregon pine. The work took over two years, and cost £35,000 (nearly $6 million in 2018 terms). The bridge span is 97.6 metres.
