The designer of the bridge, John Alexander Low Waddell (1854–1938), based the Snowden Bridge on the South Halsted Street Bridge (1893) in Chicago. When completed, Snowden Bridge was the longest (1,159 feet) vertical-lift bridge in the world. Its cost was US$465,367, equivalent to at least $10,000,000 at the beginning of the 21st century.The War Department required the movable span on the grounds that large steamboats might venture up the Missouri during the month or so that the river was navigable that far north. A kerosene engine in the lift house could raise it 43 feet in about thirty minutes. In theory, the movable span might also be lifted by a hand-turned capstan. The span was last raised in 1935 and the lift machinery removed in 1943.In 1925 a plank roadbed was built for one-way vehicular and foot traffic, while the bridge continued to be used by the Great Northern Railroad. Although a long bridge with one-way traffic and shared with railroad trains should have been spectacularly hazardous, a 1981 study found that it was "so dangerous that it [was] safe" because drivers were extraordinarily cautious when crossing it.In 1977, when the Burlington Northern moved to exclude motor vehicles from the bridge, funds for a modern road bridge were appropriated and the new MonDak Bridge was completed nearby in North Dakota."@en }
