Champlain Bridge

The Champlain Bridge (also known as the Crown Point Bridge) crosses Lake Champlain between Crown Point, New York and Chimney Point, Vermont. Constructed in 1929, it is one of the only bridges across Lake Champlain, as transport across the lake is mainly by ferry. The bridge connects Bridge Road (NY 185) in New York to VT 17 in Vermont.

The half-mile, two-lane bridge is owned by New York and Vermont. Its historic design has significance because it was built with half-a-through truss and half-a-deck truss, one of the few bridges in the nation with such a design. A truss is a type of bridge structure that uses structural components arranged in a series of triangles. Trusses have great load carrying capacity for their weight and allow the use of longer bridge spans.

The bridge was last rehabilitated in 1991.

Construction work included painting steel and bearing exteriors, repairing pier surfaces, and replacing the bridge deck, joints and railings.
