NRHP Nomination Form

"Each steel truss span has a web configuration of diagonal members that are in tension and vertical posts that are in compression. The intersection of diagonals and counter bracing occurs in the two middle panels of each span. A defining feature of the Parker truss span is the polygonal top chord. Gradual inclined members and a progression of shortened vertical and diagonal members are elements of the Parker’s truss and top chord. This design is able to achieve span lengths equal to its predecessor the Pratt truss while using less steel. The Parker’s polygonal top chord achieved longer span lengths while allowing greater savings in materials and weight."
