Duluth is a city located in northeastern Minnesota, on the westernmost point of Lake Superior. It is known as the "Gateway to the Great Lakes" and is a major port for freight transportation. The city's port is the largest on the Great Lakes, handling over 35 million tons of cargo annually. Duluth's strategic location on Lake Superior has made it a hub for shipping goods such as iron ore, coal, grain, and timber.

The history of freight transportation in Duluth dates back to the late 19th century when the city became a key player in the iron ore industry. The discovery of vast iron ore deposits in the Mesabi Range, located just west of Duluth, led to a boom in mining and shipping. The city's harbor was expanded to accommodate larger ships, and railroads were built to transport the iron ore from the mines to the port. Today, Duluth continues to be a major center for the shipping industry, with a diverse range of cargo passing through its port.
