The 126-foot-long Groveton, New Hampshire, Covered Bridge over the Upper Ammanoosuc River, constructed in 1852. The bridge was built by Captain Charles Richardson and his son. When U.S. Route 3 was reconstructed in 1939, the Groveton covered bridge was bypassed. It was repaired by Milton Graton and his son Arnold in 1964-1965. A water supply line is suspended beneath the bridge. Photo by Carol Highsmith.
