Renwick Road Bridge, Plainfield, Will County, IL

Significance: This single-span bridge, located near a historic site on DuPage River is a through Pratt truss, 151 feet in length, the last surviving through truss in Will County, and an example of a bridge type once familiar in Illinois. This truss, built by the Wrought Iron Bridge Company, is one of three spans in the state known to have been built by this prolific Canton, Ohio, builder. Pin-connected Pratts were a common late 19th and early 20th century metal truss design which is vanishing from the American landscape.
