1. The Construction of the Lethbridge Viaduct / La construction du Viaduc de Lethbridge Marker
[English] This Canadian Pacific Railway viaduct, built between 1907 and 1909 across the Oldman River Valley, was an engineering triumph. More than 1,600 metres long and 95 metres high, this steel structure is the longest and highest of its kind in Canada. The designers and labourers had to overcome daunting technical challenges during construction as a result of harsh conditions such as violent winds, dry soils, and extreme temperatures. By allowing significantly longer trains and shorter transit times, the Lethbridge viaduct greatly increased the capacity of the Crowsnest Pass Route.
