Rising 307 feet from the valley floor this bridge over which runs the Canadian Pacific Railway spans the valley in one mile and forty-seven feet. Completed in 1909 it is the longest and highest steel trestle bridge of its type in the world. Johnston's book uses numerous archival photographs to clearly explain the building of this remarkable structure which is today considered Lethbridge's most memorable landmark.
