This bridge crosses the Susquehanna River between Havre De Grace and Perryville, MD. Although it crosses Garrett Island in the middle, it is a continuous bridge consisting of 38 spans.

The west side of the river has a 500+ foot through Pennsylvania truss and 8 230 foot deck truss spans. The east side has a 500+ foot deck 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.

CSX - Susquehanna River Bridge
Posted November 20, 2014, by Nathan Holth (webmaster [at] historicbridges [dot] org)

The 500+ foot spans would have been among the longest simple truss spans when built. The 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.
