The Sunfish Slough Rail Bridge is the third of three rail bridges that make up the Mississippi River crossing at Clinton, Iowa. This 1909 bridge replaced an 1878 iron bridge, which replaced an 1860 wooden trestle. The piers are interesting in that they consist of two round cylinders connected by metal cross-bracing.

The photo above is looking north from an RV campground located on the Illinois side of the river. The photo below is taken from the highway bridge that runs just north of the rail bridge. These two photos show two different sections of the bridge. The lower photo shows the east end of the bridge, while the upper photo shows the western end of the bridge.
