Saint Lawrence Seaway

U.S.-Canadian waterway and lock system.

Located along the upper St. Lawrence River, it links the Atlantic Ocean with the Great Lakes. Its construction, carried out in 1954–59, involved clearing a 186-mi (299-km) stretch of the St. Lawrence River between Montreal and Lake Ontario. It included lakes, rivers, locks, and canals that extended for 2,340 mi (3,766 km) to connect Duluth, Minn., with the head of the Gulf of St. Lawrence. With the Great Lakes, it provides 9,500 mi (15,285 km) of navigable waterways. It allows deep-draft ocean vessels access to the Great Lakes' rich industrial and agricultural regions. It is navigable from April to mid-December.
