Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The single span, 38'-long, reinforced concrete deck arch bridge built in 1940 has concrete abutments and flared wingwalls. The concrete parapets are horizontally scored with stepped end posts. The bridge is a late example of this common bridge type with no unusual or noteworthy features. It was built by the state highway department as part of improvements to US 22. It is not historically or technologically distinguished by its setting or context. The bridge was field inspected at the request of PHMC because of its proximity to the State Farm Show Building. The bridge is separated from the building by a wide expanse of parking lot. The bridge, built as part of a routine state highway improvement project, has no significant historical association with the development of the State Farm Show and is not located on the property.
