Yeakle's Mill Bridge

Why it's listed
Near Cherry Run in Warren Township, Franklin County, a single-span metal truss bridge crosses Little Cove Creek. The bridge has a main span of 70 feet within an overall length of 76 feet, and it is a Pratt pony truss, meaning the truss sits below the deck with a through-truss form, using latticed channel columns and pin and riveted connections. The Pittsburgh Bridge Company fabricated the superstructure in 1888, according to a bridge plaque. The superstructure is iron, and the stone piers and wingwalls are coarse stonework. Its builder and designer are not recorded, although the survey identifies Nelson and Buchanan of Chambersburg in the documentation. Bolted splice plates on the top chords are a recorded alteration. The bridge is one of six Pratt pony trusses in a multiple-property group, and it is one of only a few metal truss bridges in south central Pennsylvania. Its significance rests on its engineering design and its survival as an example of this type of bridge in the region.
Significance in brief: The document describes the bridge as a representative example of a Pratt pony truss and notes that it is one of only a few metal truss bridges in the south central portion of Pennsylvania. It is one of six Pratt pony trusses included in the nomination. The area of significance is engineering, under Criterion C.

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.
