It carries a private lane over Dry Run for {{convert|30|ft|m}}.[2] Around the turn of the 20th-century Clayton County contracted with various firms and individuals to build bridges across its rivers, streams and ditches. Short spans like this one generally had a timber stringer structure. They were inexpensive, but they didn't last long. They were eventually replaced by steel stringer structures. For the most part, that transition did happen until after 1900. That makes this steel stringer bridge, erected in 1898, quite rare. It is the oldest known structure of its kind in Iowa.[2] A.C. Boyle was paid $184.50 to erect the bridge. In 1907 A.J. Nading was paid $471 to build two new stone abutments. This bridge was listed on the National Register of Historic Places in 1998.[1] References1. ^1 {{NRISref|2009a}} {{Registered Historic Places}}{{NRHP in Clayton County, Iowa}}{{Iowa-NRHP-stub}}{{Iowa-bridge-struct-stub}}2. ^1 {{cite web|url={{NRHP url|id=98000803}}|title=Dry Run Bridge|publisher=National Park Service|accessdate=2016-09-01|author=Clayton B.
