In 1980, this bridge was described as one of only approximately 28 remaining bowstring bridges in Iowa and one of four remaining bowstring bridges in Jones County. It was erected in 1875 and is the second oldest surviving iron truss bridge in Jones County and the oldest remaining bridge built by the King Iron Bridge Company in the county today."
