From Wikipedia: http://en.wikipedia.org/wiki/Lethbridge_ViaductThis 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.
