- Significance: The bridge's main span, a pin-connected Parker through truss, is an exceptionally long example of its type. Its length surpasses the practical limit of 300', beyond which a subdivided Pennsylvania truss was commonly used instead. The span and its approaches are integral to the 52nd Street Station complex, rebuilt during the Pennsylvania Railroad's campaign to separate passenger and freight traffic in the 1900s.
