Hartland Covered Bridge National Historic Site of Canada

A striking feature in the New Brunswick landscape is the Hartland Covered Bridge, considered to be the longest covered bridge extant in the world. Its massive concrete piers support a long, enclosed wooden bridge, held up by Howe trusses. The bridge offers protected crossing of the Saint John River at the Village of Hartland. The designation refers to the bridge structure and cladding on its piers.

Hartland Covered Bridge was designated a national historic site of Canada because this structure is considered to be the longest covered bridge extant in the world.

The heritage value of this site resides in its design and physical fabric. The structure, 390.75 metres long, is believed to be by far the longest covered bridge extant in the world. Covered bridges date from the first decade of the 19th century when North American buildings began using wooden trusses for long spans and covered them to prevent the truss joins from rotting. After 1840 the Howe truss, which introduced iron tension rods into the truss work, was widely adopted and New Brunswick erected numerous bridges using this technique, among them this one, built in 1901 with a walkway added in 1945
