Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The 1927, skewed, single span, 123'-long, reinforced concrete deck arch bridge has concrete abutments and concrete balustrades. The bridge has no innovative or distinctive details. An example of a common technology used with great frequency since the early 20th century, it is one of nine examples of its type and design in the county; the earliest dates to 1913. Other examples better represent the technology in the county context, such as 31 7225 0370 3014, a National Register-listed, 2 span, 117'-long, reinforced concrete deck arch bridge erected in 1917.
