This deck girder bridge crosses high above the Iowa River in Iowa Falls.
Built in 1944, the bridge contains six deck girder spans crossing the Iowa River and a small road. The bridge was built to replace an 1895 vintage deck truss. This in turn replaced a wooden covered deck truss, which burned.
The deck girders on the end each use a variable depth, likely to avoid the bluffs below. This gives one end the appearance of being "fishbellied".
The substructures are a combination of encased stone, concrete and a steel tower on either end. The older stone abutments on either end can still be seen.
Overall, the bridge appears to be in good condition, with little significant deterioration.
