Notes
  • Significance: Salisbury Street Bridge was built in 1879 for the Chesapeake and Ohio Canal Company by the Patapsco Bridge and Iron Works, Baltimore, Maryland; Wendel Bollman, proprietor. It is a single-span, wrought-iron, pony-Pratt truss spanning 67 feet over the C.O. Canal. The bridge has a construction depth of 9 feet and is 13 feet, 3 inches wide. It is one of two known surviving Bollman-built bridges of this simple, pony-Pratt type in the State of Maryland (not to be confused with the Bollman suspended and trussed bridge at Savage, Maryland, for which he received a patent). Wendel Bollman, whose company manufactured this bridge, is notable as an engineer for his design of an iron suspended and trussed bridge which was one of the first all-iron bridges used consistently by a railroad. Salisbury Street Bridge is significant for its association with Bollman and because it is an early example of an important, standard truss type, in unaltered condition.
