The completion of the Welland Canal in 1829, and its subsequent enlargements, allowed ships to bypass Niagara Falls and navigate between Lake Erie and Lake Ontario. This canal, combined with the Saint Lawrence Seaway project completed in 1959, created a continuous navigation channel from the Atlantic Ocean to all five Great Lakes. The Seaway project involved deepening channels, building new locks, and dredging harbors to accommodate larger ocean-going vessels, opening the Great Lakes to global shipping.
