West Auburn Bridge is a historic structure located northwest of West Union, Iowa, United States. It spans the Turkey River for 181 feet (55 m).[2] In 1880 the Fayette County Board of Supervisors contracted with Minneapolis engineer Horace E. Horton to design and build this bridge. The Whipple through truss bridge was completed for $7,598.79. At the time of its nomination it was one of only eight bridges of this design known to exist in Iowa.[2] The West Auburn Bridge was listed on the National Register of Historic Places in 1998.[1]
