Description 

There were two truss bridges on this road that crossed a river by way of an island. Both were demolished and replaced with a slab.

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The single span, 95'-long, pin-connected metal Pratt thru truss bridge built in 1889 is supported on stone abutments. The truss is composed of built-up compression members and eye bar tension members. The hangers in the end panels, originally double-looped, have been replaced by single-looped hangers. Rolled section floorbeams carry steel stringers and an open steel grid deck placed in 1969. Earlier railings have been replaced by W-beam guide railings. The alterations have resulted in some loss of original fabric, but the bridge retains over all integrity of original design. The bridge is a historically and technologically significant example of its type/design by an important late-19th-century fabricator. The Wrought Iron Bridge Co. was among the best known and most successful bridge fabricators to market and popularize the pin-connected truss designs for highway applications.

Here are three photos of one of the two bridges from PennDOT's VideoLog (PennDOT's own personal Streetview type tool). The other bridge had already been slabified when the video log was taken so I only have photos of the one.

What amazes me is that these "twins" appear to lead into a recreational area of some kind. Would seem like the perfect setting for an historic bridge (or two)....but who am I kidding, this is Pennsylvania we're talking about.

I haven't given one of my awards away lately.....and this debacle deserves one for each bridge

These two bridges can be seen very well on Bing Maps - Birds Eye is available for this area.
