Built in 1866 at a cost of $9,000, the Cornish-Windsor Bridge is the longest wooden bridge in the United States and the longest two-span covered bridge in the world. The fourth bridge at this site, the 460-foot structure was built by Bela J. Fletcher (1811-1877) of Claremont and James F. Tasker (1826-1903) of Cornish, using a lattice truss patented by architect Ithiel Town in 1820 and 1835. Built as a toll bridge by a private corporation, the span was purchased by the state of New Hampshire in 1936 and made toll-free in 1943.
