This bridge's trusses are completely composed of rolled beams. The most unusual feature of the bridge is the fact that the bottom chord connections to the lower gusset plates are pinned, which is quite unusual for a 1930s bridge. All other connections, including the diagonal members' bottom chord connections are riveted. The Historic Bridge Inventory notes this made it easy to assemble the bridge. The Inventory is either outdated or incorrect in saying this detail is common in the region. It is an unusual detail, and the preservation of this bridge should be considered for this reason, and also the fact that the bridge appears to be in decent shape and thus easy to keep in service of properly maintained and presereved.
Information and Findings From Pennsylvania's Historic Bridge InventoryDiscussion of Bridge The 2 span, 259' long, Warren with polygonal top chord pony truss bridge is supported on concrete abutments with wingwallls and a concrete pier. The members are rolled section, and it has riveted connections save for the lower panel points that are pinned. The approximately 125' long spans are long for pony trusses, and the pinned lower chord connections are for ease of construction. Bridges with this detail are not uncommon in the region. Neither the 1931 bridge nor its setting and context are historically or technologically significant. Discussion of Surrounding Area The bridge carries a 2 lane road over a stream in a sparsely developed, wooded setting just north of the SR 982 and SR 30 cloverleaf. Bridge Considered Historic By Survey: No |
