This standard deck girder bridge crosses a branch of Spring Branch between Manchester and Delaware.
Originally constructed in 1899, the deck girder was relocated to this location in 1955 to replace an older stone arch. The bridge is set onto concrete pile piers and approached by trestle spans.
It is believed the former stone arch bridge likely collapsed from flooding. It is unknown where the girder was relocated from, but it is believed its original location likely was along the Dubuque-Omaha line in Iowa.
Overall, the bridge remains in very good condition.

The author has ranked this bridge as being locally significant, due to the common design.
