The Marsh Rainbow Arch Bridge, also known as the Coon River Bridge and Rainbow Bend Access, is located south of Lake City, Iowa, United States. The three-span bridge carried traffic on Iberia Avenue over the North Raccoon River. with It was designed by Des Moines engineer James Barney Marsh in his patented rainbow arch configuration, and constructed by the Iowa Bridge Company in 1914 for $10,970. It replaced a Howe truss bridge that had been built by the King Bridge Company of Cleveland. That bridge was put in service upstream and remained in use until 1983 when it was taken down. The Marsh arch bridge was bypassed in 1985, and remains in place in a county park. It was listed on the National Register of Historic Places in 1989. Read more on Wikipedia
