Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The 3 span, 126'-long stone arch bridge with has bullnosed piers, ashlar voussoirs, and fieldstone spandrel walls with iron tie rods. The fieldstone parapets extend over the flared wingwalls to enclose the approach roadways. With the exception of replacement concrete coping and some heavy repointing to sections of the parapets, the bridge appears to be complete and unaltered. The BMS lists a date of construction of 1870. Although the date is appropriate, the source of the date and the builder are not documented by available records. The bridge is the earliest, most complete, longest, and finest of at least four stone arch highway bridges from ca. 1870 to 1901 identified in Adams County. It is a historically and technologically distinguished, multiple span example of the traditional bridge type.

DISCREPANCY: PA data says 126' in length whereas NIB says 61' Wiki states: It was built between 1800 and 1823, and is a 75-foot-long (23 m), triple-arched fieldstone bridge.
