Harringworth Viaduct Survey

This month DPSS have been surveying the Harringworth Viaduct , all 1275 yards of it!

The Harringworth Viaduct, also known as Welland Viaduct and Seaton Viaduct crosses the valley of the River Welland between Harringworth in Northamptonshire and Seaton in Rutland. It has 82 arches, each of which has a 40 feet (12 m) span. It was completed in around 1878 and is the longest masonry viaduct across a valley in Britain. It is the longest structure of its type on Britain’s Railway Network.

The Harringworth Viaduct is a grade II listed structure, it comprises 82 arches, each with a 42ft (12.7m) span.  The average height of the arches is 57ft (17.2m), but the highest is 70ft (21.2m). The viaduct is constructed from some 30,000,000 bricks, all manufactured on site, with Derbyshire Gritstone springers, string courses and coping. As well as the bricks, construction required some 20,000 cubic yards of concrete, 19,000 cubic yards of stone, 37,543 cubic yards of lime mortar, and 5,876 cubic yards of cement. The project was started in March 1876, and all 82 arches completed by July 1878.
