Anderson Bridge was built across the Rock River in 1900, on the northwest edge of Doon, Iowa.
About thirty miles southeast of Sioux Falls, South Dakota, Doon is a town of 577 people, and the hometown of western novelist Frederick Manfred, who published 22 novels between 1944 and 1992.
Anderson Bridge is a riveted Pratt Through Truss bridge, and it was open to traffic at the time of our visit in 2016. It actually looked like it was in pretty good condition compared to many of the old automobile bridges we’ve photographed.
The Rock River lives up to its namesake with large boulders and rock formations jutting from the riverbed in various places.
This Rock River crossing is a beautiful setting.
