This riveted swing span is flanked by uncommon pin-connected Camelback truss
spans. The pin-connected approach spans stand out, as there are other swing
bridges built at the same time on this same railroad line, but those spans have
shorter, rivet-connected approach spans. The longer span length may explain why
pin connections were used. Also of interest, the railroad erected this bridge
using its own forces, while other bridges on the railroad line were erected by a
hired contractor. Pin-connected trusses were traditionally easier to erect, so
perhaps that is why the railroad erected this one using internal forces.
