Historical information

The Pipe Bridge at Greensborough is a significant and highly visible part of the system. It was constructed to carry the wrought iron aqueduct pipes over the Plenty River. The use of wrought iron meant the pipes were 75% lighter than cast iron, with the bridge construction reflecting this innovation.

The bridge carried two wrought iron tubular mains, 53 inches in diameter, supported at intervals by cross girders and chairs, placed between the main girders.
The bridge is carried on braced cast-iron columns, 18 inches in diameter, set on concrete foundations, with a clear headway of 20 feet above the Plenty River. The eastern side of the bridge is reinforced with a bluestone abutment at the river bank.
