Notes
  • Significance: This bridge is notable as one of the few Pennsylvania trusses in Vermont. The Pennsylvania truss is basically a Parker truss with subdivided panels, permitting additional floor beams between major verticals and thereby a cheaper floor and truss system. Accordingly, its use was generally limited to spans of more than 200' length. The extensive use of members built up by riveting plates, channels, angles and lacing bar is typical of the early 1920s. Later on, such members were more often simply rolled I-beams, a cheaper and faster alternative. This is the only known surviving bridge in Vermont fabricated by the Standard Engineering and Contracting Company. It is eligible for inclusion in the National Register of Historic Places.
