Significance: This bridge, a combination of pinned Pratt trusses and a pinned Baltimore truss, is a unique type for Iowa. It is in relatively good and unaltered condition for such an old urban bridge in daily use. A product of the joint construction efforts of the City of Burlington and the Milwaukee Bridge and Iron Works, this bridge is a well preserved example of the work of a firm that was in business for a quarter century (until its absorption by American Bridge Company), but about which relatively little is known.
