View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge was built in 1923. In some respects it looks like a 1923 bridge, with members that are a little heavier than earlier bridge, but in many ways it still looks like a bridge from earlier years with its narrow roadway, and simple a-frame portal bracing. The bridge has struts (sway bracing) of an unusual lattice design. The bridge also retains large lattice railings. V-lacing is present on other truss members. The plentiful v-lacing and lattice on this bridge make it look quite visually complex.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 2-span, 256'-long, rivet-connected Pratt thru truss bridge built in 1923 has all built-up members of standard steel sections. It has lattice railings, rolled floorbeams and stringers, open steel grid deck, and fieldstone abutments and pier with concrete caps. The rivet connected Pratt thru truss type/design came into increasing use in the 1890s as a result of improvements in field pneumatic riveting equipment, and it was common by the first decade of the 20th century for highway applications. The Pratt truss type/design is the most common in the state with over 375 examples. This later example is complete, but it has no unusual or noteworthy features. The bridge is not historically or technologically distinguished by its setting or context. It is not located in a potential historic district.

Discussion of Surrounding Area

The bridge carries 1 lane of a 2 lane road over a stream in a rural village setting of Rockhill. At the western quadrants are modern modular homes and altered late 19th century brick vernacular houses. At the east end is a T-shaped intersection with a local road, woods and open fields. A stone dam is upstream and a filled-in mill race is under the east span, but the associated mill has been lost. The setting does not have the cohesiveness or integrity of a historic district.

Bridge Considered Historic By Survey: No
