Kopu Bridge (NZ)
Kopu Bridge, originally known as Hauraki Bridge, is a steel and concrete road viaduct crossing the Waihou estuary, near the town of Thames.
It was constructed in 1926-1928. There are 23 steel spans on concrete piers, and a central swinging span 42.7 m long, providing a rare surviving example of a swing span bridge in New Zealand.
Designed by John Ernest Lelliott Cull. Onslow Garth Thornton (1890-1972) was the site construction engineer.
