Description 

This bridge is clearly an example of an early Pratt/Whipple truss bridge built by the Pittsburgh Bridge Company. It shares the lattice portal bracing of other early bridges by the company, but much more importantly it has unusual framed lower chord pin connections that are identical to documented bridges by this company from the early 1880s.

This bridge is not a King Bridge company bridge it is absolutely an example of the Pittsburgh Bridge Company.

Minor/Superficial Evidence: It shares the lattice portal bracing of other early bridges by the company,

Critically Important Evidence: It has unusual framed lower chord pin connections that are identical to documented bridges by this company from the early 1880s.
