Located between Alden and Williams, this deck girder bridge crosses the South Fork of the Iowa River just west of B Avenue.
Built in 1931 and 1952, the bridge consists of a two span deck plate girder, set onto concrete substructures. Two plaques on the east span identify the build date of 1931, as well as McClintic-Marshall as the builder. However, the west span was reportedly built in 1952.
It is unknown why one span was installed here in 1952. However, it looks very similar to the 1931 span, possibly indicating it was relocated here.
This type of bridge is excellent for crossing small streams like this. It is easy to construct and easy to maintain. It appears the east span of the bridge was completed after McClintic-Marshall merged with Bethlehem Steel in 1931.
Overall, the bridge appears to be in good condition, with no significant defects noted.
The author has rated this bridge as being locally significant, due to the common design and small size.
