Significance: Configured as a pin-connected Whipple (or double-intersection Pratt) through truss, the Hardin City Bridge is one of only eight such structures remaining in Iowa. It is the only bridge in Iowa by the short-lived Western Bridge Works, Fort Wayne, Indiana. With its Whipple web configuration, cast-iron hip blocks and bearing shoes, and rolled wrought-iron components, the Hardin City Bridge typifies wagon bridge construction of the late 1870s.
