At the time of its construction, it was the world's largest viaduct and a major feat of Victorian engineering. Stockport Viaduct is a Grade II listed structure, and remains one of the world's biggest brick structures.
It took 21 months to construct, cost £72,000 and around 11 million bricks and 11,300 cubic metres of stone were used.
It has 22 semi-circular arches with spans of 19.2 metres and is flanked by pair of abutment arches of 5.5 metre span. The arch rings are 900mm thick.
The viaduct is mentioned in literature in the introduction to the Northern Mill Towns in Elizabeth Gaskell's North and South. In the creative arts, it has been portrayed in works by L.S. Lowry.
