It was listed on the National Register of Historic Places in 2014. During 1926-1941 at least 1,242 timber stringer bridges were built in Montana; this is one of very few intact survivors.[1] It was listed as part of a statewide study of timber stringer bridges.[2] It was built by Emil Prahl and Henry Sawtell, both of Miles City, to standardized plans provided by the Montana Highway Department. It is a five-span continuous treated timber stringer bridge which is {{convert|95|ft|m}} long and {{convert|20|ft|m}} wide with roadway width of {{convert|19|ft|m}}. Its ends are supported by timber abutments and wingwalls braced with wood pilings. The spans are between four sets of treated timber pile bents made of Douglas fir.[3] References1. ^1 {{cite web|url=https://www.nps.gov/nr/feature/places/14000079.htm |title=Cottonwood Creek Bridge |publisher=National Park Service}} {{National Register of Historic Places}}{{Montana-NRHP-stub}}2. ^{{cite web|url=https://www.nps.gov/nr/feature/places/pdfs/64501199.pdf |title=National Register of Historic Places Multiple Property Documentation: Montana's Historic Timber Stringer Bridges, 1915-1960 |publisher=National Park Service |author=Jon Axline |date=January 5, 2014 |accessdate=May 23, 2017 }} 3. ^{{cite web|url=https://www.nps.gov/nr/feature/places/pdfs/14000079.pdf |title=National Register of Historic Places Inventory/Nomination: Cottonwood Creek Bridge / 24FA0231/MDT Identification No. S00320002+02001 |publisher=National Park Service|author=Jon Axline |date=May 24, 2013 |accessdate=May 23, 2017 }} With seven photos from 2013. 4 : National Register of Historic Places in Montana|Bridges completed in 1934|Road bridges in Montana|Fallon County, Montana |
