The 1929 Lake Champlain Bridge

Science & Tech
6
When it opened in 1929, the Lake Champlain Bridge became the first modern highway bridge to cross 120-mile-long Lake Champlain and established a direct motor route between New York’s Adirondacks and Vermont’s Green Mountains, linking the Empire State to New England. It was one of the first highway bridges in the country to use continuous-truss technology, with an innovative, cost-effective design whose elegant form complemented the surrounding scenery and whose open structure provided broad views of the lake and mountains. Its channel segment featured two deck trusses flanking an arched central through truss that rose 132 feet above the lake’s surface. In 2009, an engineering study found the bridge unsafe for repair and recommended immediate controlled demolition, which occurred on December 28 of that year. The current bridge opened in 2011, with a design chosen with strong local community involvement to evoke the shape and appearance of the historic structure.
