Stockport Viaduct

Stockport Viaduct carries the West Coast Main Line across the valley of the River Mersey in Stockport, Greater Manchester, England. It is one of the largest brick structures in the United Kingdom and a major structure of the early railway age.

The viaduct was designed by George Watson Buck in consultation with the architect John Lowe for the Manchester and Birmingham Railway. Work began in March 1839 and despite its scale and flooding from the Mersey, the viaduct was completed in December 1840 and services commenced the same month. Roughly 11 million bricks were used in its construction; at the time of its completion, it was the world's largest viaduct and a major feat of engineering.
