The High Level Bridge: more than 1,600 metres long and 95 metres high over the Oldman River, built 1907–1909 for the Canadian Pacific's Crowsnest Pass route and still carrying trains. Parks Canada calls it the longest and highest of its kind in Canada; its construction is a National Historic Event (designated 2005).
