Lethbridge Viaduct - Overview

Overview

This massive steel trestle over the Oldman River was designed by the Canadian Pacific Railway's bridge department in Montreal. The field work was directed by CPR's Assistant Chief Engineer John Edward Schwitzer. The steel work was manufactured by the Canadian Bridge Company of Walkerville, Ontario. A 100 man gang worked on the erection of the steel. Although there were some initial problems with settlement, the bridge has proved to be an enduring engineering work and is still in use today.

This bridge is the largest railway structure in Canada. It was built as part of a major diversion of the Crowsnest Pass route between Lethbridge and Fort Macleod. The river crossing was previously over a wooden trestle measuring 894 m (2,933 ft) long and 20 m (66 ft) high; an impressive structure in its own right.
