Smith Bridge

Named for local farmer Jacob Smith, the first bridge at this site was begun before 1786 and completed with the aid of a lottery authorized that year. In 1850, contractor Harmon Marcy of Littleton, N.H. built a new bridge at a cost of about $2,700 using a pre-stressed wooden truss patented by Col. Stephen Harriman Long (1784-1864) of Hopkinton, N.H. After an arsonist burned the 143-year-old span in 1993, the state constructed a two-lane bridge built with glued-laminated timbers and arches at a cost of $3.3 million and dedicated in 2001, designed to bear the same loads as interstate highway bridges.
