The Duluth Ship Canal, also known as the Duluth-Superior Harbor, is a vital waterway that connects Lake Superior to the Duluth-Superior harbor. The canal is approximately 1.5 miles long and 300 feet wide, allowing large vessels to pass through and access the harbor. The canal’s history dates back to the late 19th century, when the city of Duluth was rapidly growing as a major shipping hub. In 1871, the U.S. Army Corps of Engineers began construction on the canal, which was completed in 1874. The canal was built to provide a safe and efficient way for ships to enter and exit the harbor, protecting them from the strong waves and currents of Lake Superior.

Over the years, the Duluth Ship Canal has undergone several renovations and expansions to accommodate the increasing size and volume of maritime traffic. In the early 20th century, the canal was widened and deepened to allow for larger vessels to pass through. Today, the canal is a critical component of the Duluth-Superior harbor, with over 1,000 vessels passing through it every year. The canal is also a popular tourist attraction, with visitors flocking to the Lake Superior Maritime Visitor Center to watch ships navigate the canal and learn about its rich history. The canal’s significance extends beyond its economic importance, as it has played a crucial role in shaping the city of Duluth’s identity and development over the years.
