Firth-of-Tay-Brücke
Bouch designed the first Tay Rail Bridge while working for the North British Railway, and the official opening took place in May 1878. Queen Victoria travelled over it in late June 1879, and she awarded him a knighthood in recognition of his achievement. The bridge collapsed on 28 December 1879, in the Tay Bridge Disaster, when it was hit by strong side winds. A train was travelling over it at the time, and 75 people died.
