Description 

The Cottonwood Creek Bridge consists of one contributing resource. The bridge is a five-span treated timber stringer structure constructed by Emil Prahl and Henry Sawtell in 1934 from standardized plans furnished by the Montana Highway Department. It is located on Secondary Highway 320 (Ismay Road) approximately three miles south of the City of Ismay in Fallon County. The bridge measures 95 feet long and 20 feet wide. The intact double rail guardrails are standard to timber stringer bridges designed by the Montana Highway Department between 1915 and 1960. The bridge is located in a rural setting and functions as a stream crossing on a farm- to-market road.
