The concrete bridge is {{convert|150|ft}} long and consists of two spans. It was built in 1936 to replace an earlier wooden bridge that had begun to deteriorate. The Weldon Brothers Construction Co. supervised the bridge's construction, while the Iowa State Highway Commission designed the structure; it was one of the first bridges designed by the ISHC, which used similar plans for many other bridges in the state. Labor for the construction effort came from the Works Progress Administration, providing jobs for many of Hardin County's unemployed residents. The bridge was dedicated on July 4, 1936, as part of Alden's Independence Day celebrations.[2] The bridge was listed on the National Register of Historic Places on May 15, 1998.[1] References1. ^1 {{NRISref|version=2010a}} {{National Register of Historic Places}}{{NRHP in Hardin County, Iowa}}{{Iowa-NRHP-stub}}{{Iowa-bridge-struct-stub}}2. ^{{cite web|last1=Crow-Dolby|first1=Michelle|last2=Fraser|first2=Clayton|title=National Register of Historic Places Registration Form: Alden Bridge|url={{NRHP url|id=98000517}}|publisher=National Park Service|accessdate=January 25, 2015|date=August 31, 1994}} {{NRHP url|id=98000517|title=Accompanied by photos|photos=y}}. 6 : Road bridges on the National Register of Historic Places in Iowa|Bridges completed in 1936|Bridges in Hardin County, Iowa|National Register of Historic Places in Hardin County, Iowa|Road bridges in Iowa|Concrete bridges in the United States |
