Bridge in Clinton Township

Approximate location: the National Park Service places this pin arbitrarily within the property, not at a surveyed point (stated accuracy ±12 m).
Why it's listed
A single-span Pratt through truss highway bridge crossing Scrubgrass Creek in Clinton Township, Venango County, Pennsylvania. The steel superstructure is 106 feet long overall, and the nominated area is a rectangle 136 feet by 25 feet, bounded by the outside corners of the wing walls. The bridge was built in 1887 by the Smith Bridge Company of Toledo, Ohio, and its only decorative element is a bridge plate on the portal. Its steel members were produced in Carnegie, Pennsylvania. Its significance rests on engineering: it is regarded as a representative example of the Pratt through truss type, which was used frequently in northwestern Pennsylvania. The bridge is considered well preserved as an example of that type. Alterations include a 1940 structural steel repair, the 1980 replacement of a cut stone box culvert with twin 48-inch metal pipe, and an asphalt overlay on the wooden deck.
Significance in brief: The nomination describes the bridge as a representative example of a Pratt through truss bridge, with typically configured members and a bridge plate on the portal as its only decorative feature. It is argued to be a well-preserved example of a bridge type used frequently in northwestern Pennsylvania, and the significance is listed under engineering.

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.
