The Canadian Northern Railway Bridge is a Canadian railway bridge that spans the North Saskatchewan River in Prince Albert, Saskatchewan.
The bridge was built by the Canadian Northern Railway between 1907 and 1909 with the superstructure supplied by the Hamilton Bridge Company. Originally designed as a joint railway and road bridge the bridge consisted of a centre rail line with 12feet extensions on each side for traffic. These traffic lanes remained in use until 1960 when the nearby Diefenbaker Bridge opened. The layout of the bridge consisted of three 146feet steel trusses, a 256feet swing span truss and two additional 156feet fixed trusses. The centre swing span was used to permit the passage of steamboats on the river and movement of logs until 1918 when the downstream sawmill shut down operations and a dam was constructed downstream in 1937. In 1939 the Department of Transport granted the railway permission to convert the moveable span into a fixed span.[2]
