Description 

The Cottonwood Creek Bridge is eligible for listing in the National Register of Historic Places under criteria A and C. The bridge is eligible under Criterion A as representative of the type of structure used by the state and counties between 1915 and 1960 to provide access to railroad stations and primary state-maintained highways from county farm-to-market roads. Timber stringer bridges were typically used to span relatively narrow obstacles such as streams and ravines. The Cottonwood Creek Bridge is emblematic of the standard timber stringer bridge in design and use between 1915 and 1960. The structure was built during the peak years of timber stringer bridge construction from 1926-1941 when at least 1,242 such bridges were constructed in Montana. The Cottonwood Creek Bridge is one of only a very few intact examples of this style remaining on Montana's primary, secondary, and county roads. (NRHP Nomination Form)
