Saint Lawrence Seaway
The Saint Lawrence Seaway, is the common name for a system of locks, canals and channels that permits ocean-going vessels to travel from the Atlantic Ocean to the Great Lakes, as far inland as the western end of Lake Superior. The Seaway is named for the Saint Lawrence River, which flows from Lake Ontario to the Atlantic Ocean. Legally, the Seaway extends from Montreal, Quebec, to Lake Erie, and includes the Welland Canal. This section downstream of the Seaway is not a continuous canal, but rather it consists of several stretches of navigable channels within the river, a number of locks, as well as canals along the banks of the St. Lawrence River to bypass several rapids and dams along the way. A number of the locks are managed by the Canadian Saint Lawrence Seaway Management Corporation and others are managed by the American Saint Lawrence Seaway Development Corporation.
