This is a long and large bridge over the wide Susquehanna River. It is noted for its variety of span types, defining which spans are "main" spans and "approach" spans is difficult given the layout of the bridge and variety of designs used. The 500+ foot spans would have been among the longest simple truss spans when built. The 520 foot deck truss span is particularly significant since most record-breaking spans are thru trusses, presumably because long spans require deep trusses that normally would not fit under the roadway level as a deck truss.
The west side of the river has a 520 foot through Pennsylvania truss and 8 230 foot deck truss spans. The east side has a 520 foot Baltimore deck truss (or it might be called an upside-down Pennsylvania truss), a 400 foot through Pennsylvania truss, and 2 230 foot deck truss spans. The spans over the island were originally girder spans, much shorter than the others. There are 23 girder spans.
