This bridge is in the middle of nowhere. In fact, you may go through a dot on the map appropriately named "Distant" on the way to this bridge!
The historic bridge inventory links the bridge to Nelson and Buchanan because of the floor beams. Nelson and Buchanan were originally agents for the Pittsburgh Bridge Company, but later became their own company. The design of the portal bracing is the standard design that Pittsburgh Bridge Company and Nelson and Buchanan used. Moreover, although the plaque is missing on Jantz Road, the outline of the unusually shaped and positioned end post plaque is clearly the same shape as other bridges associated with Pittsburgh Bridge Company and/or Nelson and Buchanan. Finally, the way that the overhead lateral bracing rods are tied into the sway bracing is identical to many Pittsburgh Bridge Company and/or Nelson and Buchanan bridges.
This bridge was reportedly to be scheduled for rehabilitation following review ca. 2010. In Pennsylvania it is often smart to believe it when you see it, but if this bridge is indeed rehabilitated, it would be one of the few preserved historic metal truss bridges in the Commonwealth, a step in the right direction away from a reputation of demolition and replacement.
Information and Findings From Pennsylvania's Historic Bridge Inventory
Discussion of Bridge
The ca. 1895, pin connected, single span, 86'-long, Pratt thru truss is supported on ashlar abutments with flared wingwalls. The trusses are traditionally composed, but the manner in which the floor beams are connected with Z-shaped straps at the lower panel points indicates that it was fabricated by Nelson & Buchanan. It is one of nine pin connected Pratt truss bridges in Armstrong County, and the bridge is historically and technologically significant as a complete example of the technology in the region. The bridge appears to be complete except for the cover plate welded to the floor beams.
Discussion of Surrounding Area
The bridge carries 1 lane of a township road over a stream in a sparsely developed, wooded setting.
