Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: "The 2 span, 166'-long, reinforced concrete deck arch bridge built in 1912 to plans developed by the county has raised paneled parapets, concrete abutments, and a concrete bullnosed pier. The bridge is one of 13 surviving deck arch bridges designed by the Blair County engineer and built between 1908 and 1913. This example has no innovative or distinctive details. An example of a common type, it was built to a standardized design that was illustrated in the engineering texts of the period. The bridge is neither technologically nor historically significant." Hence in PENNDOT's eyes bridge is being demolished as seen in the photos from May 22, 2011.
