Quaker Bridge
Why it's listed
Built in 1898 by the Cleveland Bridge Company, Quaker Bridge carries vehicle traffic across the Little Shenango River in Hempfield Township, Mercer County, in northwestern Pennsylvania. It is a single-span Pratt through truss of steel, with a span of 124 feet over all, and its superstructure was sourced from Carnegie, USA. The truss uses pin and riveted connections, eyebar members and a diamond railing, and its deck is open grated metal. The bridge is recognized as a typical example of the Pratt through truss type. Its significance lies in its engineering: it is considered a well-preserved example of a bridge type common in the region. The bridge is unaltered and remains in its original location, which the nomination cites as the basis for its importance to the study of regional bridge construction.
Significance in brief: The nomination describes it as a typical example of a Pratt through truss bridge and a well-preserved representative of a bridge type used frequently in northwestern Pennsylvania.

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.
