Comments
Dry Run Creek US 52 Bridge
Orginally named the "Hog's Back Bridge," but the name never took hold. In the late 1940s a cut was made through a limestone ridge - called the "Hog's Back" - to divert the Dry Run Creek directly into the Upper Iowa River. Prior to that, Dry Run Creek ran through Decorah and every year it would flood. The diversion of the Dry Run Creek plus a dike along both sides of the Upper Iowa River eliminated the problem with annual flooding.
