State Street Bridge (Mason City, Iowa)

The State Street Bridge is a historic structure located in Mason City, Iowa, United States. The span carries East State Street over Willow Creek for 62 feet (19 m). In the mid- to late-19th century, State Street was the only road into town from the east. There was a bridge at this crossing from at least 1875, but it is unknown what kind of bridges or how many served the crossing.[2] This bridge was completed in 1903 and features a barrel arch with filled spandrels. Although the original guardrails have been replaced, it is the oldest roadway arch bridge in Cerro Gordo County.[2] It was listed on the National Register of Historic Places in 1998.[1]
