The Boone River Bridge is a historic structure located north of Goldfield, Iowa, United States. It is a 6-panel, 128feet Warren Pony truss span over the Boone River.[1] The construction began in 1910. The bridge was built in 1912 by the Iowa Bridge Company using steel fabricated at the Cambria steel mills in Johnstown, Pennsylvania. The Boone River Bridge is one of the few remaining multiple span pin-connected Pratt trusses in the state. It was listed on the National Register of Historic Places in 1998.[2]
The bridge was rehabilitated in 1940.[3]
