Tiskilwa Bridge, Toconship Road 236 over Bureau Creek, Tiskilwa, Bureau County, IL

Significance: This three span bridge, located at a historic crossing on Bureau Creek, includes two Pratt truss spans. The 119' span is an early example of a Through Pratt built by the Smith Bridge Company, one of two spans in Illinois known to have been built by this prominent and prolific Toledo, Ohio, builder. The 60' pony span was built by the Decatur Bridge Company of Decatur, Illinois, a smaller bridge building company with bridges believed to have been generally limited to Illinois. Pin-connected Pratts were a common late 19th and early 20th century metal truss design which is vanishing from the American landscape.
