Boston & Maine Railroad, Northampton Lattice Truss Bridge, Northampton, Hampshire County, MA
Summary
Significance: This structure is an early example of an all-riveted metal lattice truss built for railroad use. The form of the riveted lattice truss reduced deflection under heavy moving loads and, apparently, provided smoother passage for trains. At the same time, it required more complicated mathematical analysis of stress than simple Pratt trusses.
