The St. Lawrence Seaway is one of the world's maritime superhighways, linking the Great Lakes to the Atlantic Ocean. The Dwight D Eisenhower Lock Visitors Center, located directly beside the lock in Massena New York, is a new interactive museum portraying the story of the Seaway's legacy and history. Celebrating the Seaway's engineering significance, economic impacts, and community engagement, it draws tens of thousands of visitors each year.
