Building/structure dates: 1908 initial construction
Significance: The Susquehanna River Bridge was constructed in 1908 to replace an older, timber Howe truss structure. The first bridge built by the B&O Railroad on this site consisted of twelve 250 foot spans, with a shorter deck truss in the center of the bridge. This structure has been said to have marked the zenith of Howe truss railway bridge construction. The existing bridge consists of a variety of Pennsylvania and Pratt trusses. The Pennsylvania trusses, one over each channel, are through trusses, and provide clearance for river traffic. The Pratt trusses are deck trusses. Three trusses carry the bridge over the eastern channel of the Susquehanna, twenty plat girders serve to cross Garrett Island, and a series (east to west) of six Pratt trusses, a Pennsylvania truss, and two more Pratt trusses carry the bridge to its western abutment. In addition, there are two approach spans, one at either end of the bridge.
