Bridge in Jenner 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
Stone arch highway bridge carrying a road over Roaring Run in Jenner Township, near Pilltown in Somerset County, Pennsylvania. Built in 1908 according to district bridge files, the structure has a single span of 31.5 feet and is constructed of rock-faced coursed ashlar with stone abutments, wings and voussoirs. Its nominated boundary is a 52 by 25 foot rectangle enclosing the superstructure and substructure. The bridge is regarded as a well-preserved example of a small late nineteenth or early twentieth century Pennsylvania stone highway bridge, with span length and masonry typical of that period. Its engineering significance lies partly in its rarity: it is one of only five stone arch bridges among those nominated in western Pennsylvania. One parapet is missing, and the bridge is recorded as altered. Good stonework is noted among its unusual features, and the setting is rural.
Significance in brief: The bridge is described as a well-preserved example of a small late nineteenth or early twentieth century Pennsylvania stone highway bridge, with span length and rock-faced ashlar construction typical of that period. It is significant under engineering because it is one of only five stone arch bridges nominated in western 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.
