The seaway is a series of locks, inland channels and the Welland Canal that operate between the Saint Lawrence River and the Great Lakes. It was an engineering masterpiece at that time and remains useful even though many of todays ships are much too large to use it; the maximum boat length is 740 feet with a width of 78 feet so barges are used for the most part.
The opening was officiated by Queen Elizabeth II and President Dwight D. Eisenhower with joint speeches while aboard the Royal Yacht Britannia at Saint Lambert, Quebec.
