Bridge in Brown Township
Why it's listed
Steel lattice truss bridge carrying a road over Pine Creek in Brown Township, Lycoming County, Pennsylvania, about one mile north of the village of Slate Run. It was built in 1890 by the Berlin Iron Bridge Company of East Berlin, Connecticut, and spans 196.25 feet. The lattice truss configuration, also termed a Warren quadrangular, is built of riveted plates, angles and lacing bars, with all joints riveted. The company was known mainly for lenticular trusses, and only two of its other bridges in the Pennsylvania highway bridge survey are known, both lenticular. Because the lattice truss type was infrequently built, owing to its structurally indeterminate nature, the bridge is regarded as a well preserved example of a fairly rare design. A new open steel deck was installed in 1960, and the bridge remains in vehicular use. Its significance lies in engineering.
Significance in brief: The nomination argues the lattice truss type is unusual and was infrequently built because of its structurally indeterminate nature. It describes the bridge as a well preserved example of a fairly rare bridge type, with riveted plates, angles, lacing bars and riveted joints. The company's other surveyed Pennsylvania bridges are lenticular trusses, which makes this lattice example distinctive. The area of significance is 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.
