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.

Yonkers is the fourth-largest city in the state of New York and is located just north of Manhattan. It has a rich history dating back to the 17th century when it was first settled by the Dutch. The city played a significant role in the American Revolutionary War, serving as a strategic location for the Continental Army. Yonkers is also known for its industrial heritage, with a history of manufacturing and transportation.

One of the key factors in Yonkers' development was its location along the Hudson River. The city became an important transportation hub in the 19th century, with the construction of the Erie Canal and the arrival of the railroad. The Hudson River served as a vital waterway for the transportation of goods, including freight. Yonkers was a major center for shipping and trade, with industries such as textiles, carpet manufacturing, and brewing thriving along the waterfront.

Today, Yonkers continues to be a hub for freight transportation, with its proximity to major highways and rail lines. The city is served by several major highways, including the New York State Thruway and the Cross County Parkway, making it easily accessible for trucking and shipping companies. Yonkers is also located on the Metro-North Railroad's Hudson Line, providing convenient access to the New York City metropolitan area and beyond. The city's industrial areas and waterfront continue to attract businesses involved in freight transportation and logistics.
