We are coming up on the 66th Anniversary of the opening of the St. Lawrence Seaway, which was officially opened on June 26, 1959. This engineering marvel required the labour of 22,000 workers, the removal of 210 million cubic yards of earth and rock, and the pouring of over 6 million cubic yards of concrete. The project cost $470 million (Canadian), with the Canadian government paying $336.2 million. The seaway transformed shipping on the St. Lawrence River, opened Great Lakes ports to ocean shipping, and facilitated hydroelectric power generation.
