Description 

This bridge is a remaining span of a seven-span approach bridge built in 1872 to serve a larger seven-span bridge built in 1868 over the Mississippi River at Dubuque. The larger bridge was the first to span the Mississippi at Dubuque, and was one of the earliest of all Mississippi River bridges. The superstructures of both the approach bridge and the river bridge were fabricated and erected by the Keystone Bridge Company, one of the most important and long-lived bridge companies of the nineteenth century. This span is one of the oldest iron trusses still in use in Iowa, and is the only Keystone truss known to be in use in the state.

This bridge was relocated in 2007 from its position over White Water Creek to a pond in the Dubuque West Industrial Park. Known as the Bergfeld Recreational Area, it is a park inside the park. The pond is stocked with fish and is surrounded by an 8/10 mile of hiking trail.

This single span is significant as one of the last extant examples of cast iron bridge technology that was popular in the mid 19th Century. The span uses unusual cast iron columns, patented by the Keystone Bridge Company, and ornamental cast iron connector blocks. It is an important piece of history, now preserved in Dubuque.
