Snowden Bridge Snowden Bridge is a high-clearance, vertical-lift railroad bridge, built in 1913, that spans the Missouri River between Roosevelt and Richland Counties in Montana, USA, between Bainville and Fairview, Montana, and near Fort Union Trading Post National Historic Site and the ghost town of Mondak near Montana's eastern border with North Dakota. 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.
