Iowa Highway 56

Iowa Highway 56 (Iowa 56) is a state highway that runs from west to east in northeastern Iowa. It begins at Iowa Highway 150 in West Union and ends at Iowa Highway 13 south of Elkader. As a largely rural route, Iowa 56 passes through the farmland of Fayette and Clayton counties. Through Elkader and to its eastern end, the highway runs parallel to the Turkey River.

The 24-mile-long (39 km) highway is an original route from 1920. It originally extended from West Union to Guttenberg, but it was shortened to Elkader by 1925. Since then, both the western and eastern endpoints have shifted slightly, but the route otherwise remains the same.
