Lethbridge Viaduct

About

The Lethbridge Viaduct, commonly known as the High Level Bridge, is a railway trestle bridge over the Oldman River in Lethbridge, Alberta, Canada. Constructed between 1907 and 1909 by the Canadian Pacific Railway, it is the largest railway structure in Canada and the largest of its type in the world, and is still regularly maintained and used over a century since its construction. In 2005, the construction of the viaduct was recognized as an event of national historic significance.
