Notes
  • Significance: The Phoenix Bridge represents two types of technology typical of late nineteenth century factory-manufactured railroad bridges. The main span is an example of a pin-connected iron and steel Pratt through truss railroad bridge of a proprietary design developed and manufactured by the Phoenix Bridge Company. The secondary span is a representative example of a steel Warren deck truss. The Phoenix Bridge Company and Aldophus Bonzano made important contributions to bridge design and construction in the late nineteenth century.
