Summary[edit]

Description
English: Beaver Bridge (Ohio River)

Pittsburgh & Lake Erie Railroad, Ohio River Bridge, Spanning Ohio River, West of Beaver River, Beaver, Beaver, PA: Overview of east elevation, looking SW. Building/structure dates: 1908 initial construction.

“The bridge is significant for its relatively long and heavy cantilever truss, planned shortly before the Quebec cantilever bridge collapse of 1907. Rather than select a different design, the railroad proceeded, implementing design checks and strict quality control procedures. Despite a conservative overall design, the bridge includes a number of innovative structural details. The substructure is also significant for its early use of concrete pier caissons.”
