The Hartland Bridge in New Brunswick is the world's longest covered bridge, at 391m long. It crosses the Saint John River from Hartland to Somerville, and the framework consists of seven small Howe Truss bridges joined together on six piers. Before the construction of the bridge in 1901 (uncovered), the only way to cross the Saint John River was by ferry.
In 1920, two spans of the bridge collapsed due to river ice. The bridge was reopened in 1922 after repairs, at which time it was also covered, and the wooden piers were converted to concrete. A pedestrian walkway was added in 1945. In 1982, the bridge was again closed for repairs after a car struck a steel beam, causing part of the bridge to drop, being reopened in 1983. In 2007 it was closed due to the central beam splitting down the middle. It has since been reopened after repairs were carried out.
