Notes
Survey number HAER NH-19
Significance: The bridge, designed by the State Highway Department, is on of approximately 15 single span high Pratt truss bridges extant in New Hampshire. A late example of a Pratt truss, the bridge is significant for its length, its 90 degree angle of crossing, and its former steel open grid walkways (now filled and paved). The bridge was constructed in 1940 during the realignment and straightening of Route 4, the state's principal east-west trunk line between Concord and the Connecticut River Valley.
