Bridge in Rockdale Township
Why it's listed
Built in 1887 by the Wrought Iron Bridge Company of Canton, Ohio, this single-span double intersection Pratt truss bridge crosses French Creek in Rockdale Township, Crawford County, Pennsylvania. It measures 129 feet overall, and the nominated property is a 149-foot by 25-foot rectangle that includes the superstructure and substructure. The steel main span rests on stone abutments and wing walls, and its pin-connected members use loop-welded eyebars. The bridge was altered in 1941, when two posts were replaced, wheel guards were installed and the abutments were repointed. The stonework is described as being in very good condition. It is one of three surviving examples of this truss type in the group, all built by the same company in the 1880s. The bridge is significant for its engineering, as a representative example of a nineteenth-century Pratt truss by a leading bridge builder.
Significance in brief: The nomination identifies the bridge as one of three representative examples of this truss type included in the group, all built in the 1880s by the Wrought Iron Bridge Company, a leading nineteenth-century bridge company. Its significance is listed under engineering. The stone work is noted as being in very good condition.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
