Bridge Documentation

Featuring a wide variety of span types including those found on its long approaches, this unique bridge is difficult to access without a boat or a job with the railroad. Having secured access to a boat, HistoricBridges.org presents a large detail-oriented photo gallery for this bridge, but with the constraint that all photos are taken from the river. The main features of the bridge are the Pennsylvania truss span, which with five slopes, has the shape of a Camelback truss, and the Baltimore truss span. However there is much more to this bridge. The bridge's sprawling, branching approaches make this railroad bridge look more like an expressway interchange from above. These approach ramps include a pin connected Pratt deck truss span over Turtle Creek, riveted Warren deck truss spans, and even a riveted Pratt deck truss span. The remainder of the approaches are supported by mostly deck plate girder spans. Lengths given are estimates. The Pennsylvania truss span appears to be a 400 foot span while the Baltimore truss span appears to be 250 feet. The overall length estimate given is the shortest crossing, straight across the river and railroad tracks, and does not consider any of the branching elevated approach trackage.

This bridge is next to another railroad bridge.
