Design
Of the three main truss spans, only the southernmost (main river channel) span should be considered a Pennsylvania through truss. The remaining truss spans are both very large Parker through trusses with horizontal stabilizing members added to them, most likely because of their very large size and length. These horizontal members make it very easy to mistake these truss spans for Pennsylvania trusses, but closer observation shows a lack of the subdivided panel members required to classify these trusses as Pennsylvania trusses.

Total length: 1,074.2 ft.
