This particular structure was fabricated by the Fort Pitt Bridge Works at their Canonsburg shop.
Pennsylvania's historic bridge inventory is a poor way to evaluate whether a bridge should be preserved. Bridges such as this one were not listed as historic, because they feel this bridge is common technology. HistoricBridges.org argues that yes, it was common technology... back in 1930! You don't find bridges such as this one being built on today's roadways. Also, sometimes a bridge is significant, not because it is unique and alone, but because it stands in a group. Such is the case with this bridge, which stands along with two others along this road. Because of their frequency on this road, the entire roadway is a unique bridge experience, that can't be had anyplace else. While aesthetics on their roads is obviously not a concern for demolition-happy PennDOT, it should be. Due to attrition, a scene like this: seeing three multi-span massive-member truss bridges within a short distance is historic. It represents what roads might have been like back to drive on in the late truss bridge era.
Information and Findings From Pennsylvania's Historic Bridge Inventory
Discussion of Bridge
The 1936, skewed, 2 span, 300'-long, riveted Pratt thru truss bridge is supported on concrete abutments and piers. In 1980 a number of verticals and diagonals had rusted areas removed and steel plate welded in their place. The bridge, built to a state highway department standard design, is an example of a common technology used since ca. 1895. It has no innovative or distinctive details. It was part of the rebuilding efforts following the devastating 1936 St. Patrick's Day flood when over 275 bridges were destroyed or damaged beyond repair. The bridge is neither historically nor technologically significant. Nor is the highway historically significant. Although now designated US 6, it was not a part of the original highway developed across Pennsylvania's northern tier. In the 1910s and 1920s it was part of SR 5, promoted as the Lakes to the Sea Highway, one of the many tourist trails in the state. Following the adoption of the federal numbering system in 1926 it was renumbered SR 19. Its was redesignated as part of US 6 following WW II.
Discussion of Surrounding Area
The bridge carries a 2 lane state highway with shoulders and a sidewalk over a stream in a sparsely developed, rural area with scattered 20th century residences just south of the borough of Saegertown. The area does not have historic district potential.
