St. Lawrence Seaway

The St. Lawrence Seaway is a system of locks, ports, and channels that connects the Great Lakes in North America to the Atlantic Ocean via the St. Lawrence River. Opened in 1959, it allows large ships to transport goods like grain, coal, and iron ore from the Midwest U.S. and Canada to international markets. This waterway is vital for trade and the economy, enhancing transportation efficiency and supporting industries in the region. The Seaway is jointly managed by the United States and Canada, reflecting the strong economic ties between the two countries.
