This viaduct is 258 feet high. It was built by Andersons Ltd, at a cost of £53,369, out of fabricated steel. It was built to take the the 11.5 axle load of the "X" class engine, and therefore had to be strengthened before the "K", with its 14.5 ton axle-load, could cross it. It had to be upgraded once again for the 18-ton impact of the "Dx" train. From "Steel Roads of New Zealand", G Troup (Ed), p 118.
