Twin Bridge, Spanning Little Volga River in Twin Bridge Park, Fayette, Fayette County, IA
Significance: With its 80-foot span, the Twin Bridge is distinguished as the longest-span Luten arch remaining in Iowa. Its designer, Daniel B. Luten, anticipating the popularity of the reinforced concrete bridge, began acquiring patents in 1900. By the 1910s, thousands of Luten arches had been constructed nationwide. Although highly prolific, his operation was not popular. He was sued for patent infringements and the Iowa State Highway Commission led a nationwide effort to defeat the Luten monopoly, marking the end of the patented-design era, and paving the way for bridge standardization.
