Port of Duluth in Minnesota — Webcam Online Traffic at Cargo Connect Terminal

Port of Duluth-Superior — Gateway to the Great Lakes

Duluth, situated on the western tip of Lake Superior, has been a key transportation hub of the Central States for more than a century and a half. The Port of Duluth-Superior is rightfully considered the largest freshwater port in the world. The waterway accommodates bulk carriers with iron ore, coal, limestone, and grain, and since 2018 the Cargo Connect intermodal terminal has been operating here. Our webcam online captures this specific port area — you can observe tugboats, cargo ships, and waterfront infrastructure in motion.

The city of Duluth, Minnesota, stands on hilly terrain that slopes down to the water, so the view from the port encompasses not only the waterway but also the urban landscape with churches and water towers. The port functions as a single complex with the city of Superior in Wisconsin — together they form the so-called Twin Ports, through which up to 40 million tons of cargo pass annually. The Great Lakes system here connects with the continental rail network, creating a multimodal corridor of international significance.

Cargo Connect: The First Intermodal Container Terminal

Cargo Connect Duluth is the first and currently only container intermodal terminal in the Great Lakes system. The facility is located at the Clure Public Marine Terminal — a 30-acre section of port infrastructure on the shore of Lake Superior. The initiative is owned by a joint venture of the Duluth Seaway Port Authority and Canadian National Railway (CN) — the only North American railroad with access to all three coasts of the continent: the Atlantic, Pacific, and Gulf of Mexico.

The terminal specializes in transloading marine containers between Great Lakes vessels, CN rail trains, and truck freight. It also handles general cargo, heavy and oversized shipments, grain, lumber, and project cargo. The terminal's concept aligns with the Highway H2O strategy — a marine corridor through the Great Lakes and the St. Lawrence River that provides an alternative to congested overland routes through the East and West Coast ports of the United States.

For businesses in Minnesota and neighboring states, Cargo Connect opens opportunities for direct import of marine containers from Europe and other regions across the Atlantic — bypassing deepwater coastal ports. Return container voyages are used for grain export from the grain basins of the Midwest, improving the efficiency of supply chains in both directions.

History: From Idea to Launch

CN and Duluth Seaway Port Authority announced the creation of the first intermodal container terminal in the Twin Ports in 2017. The plan was for the new hub to connect Great Lakes shipping routes with the extensive Canadian National Railway network, giving regional manufacturers and distributors direct access to international markets. The official launch took place in April 2018 — the terminal began receiving and dispatching container trains.

Already in its first years of operation, the terminal proved its demand. In 2019, the port authorities purchased the neighboring dock for $950,000 to expand transloading capacity. In 2021, a phase of modernization of marine container operations at Clure Public Marine Terminal was completed. And in 2024, the Intermodal Terminal Expansion Project was unveiled — a plan for further increasing the hub's throughput capacity.

According to Deborah Dell, Director of Development at Duluth Seaway Port Authority, Cargo Connect "changed the game" for businesses pursuing global expansion using the Port of Duluth and the CN network. The terminal has become a catalyst for container shipping through the Great Lakes — today thousands of containers travel this route annually, and the number continues to grow.

Transport Arteries: Rail and Highway

The logistical value of Cargo Connect is defined by its multimodal connectivity. Canadian National Railway provides rail service connecting the terminal with Chicago, Memphis, New Orleans, and major cities in Canada. CN rail sidings allow the formation of trains to transport containers to any point in North America — from the Gulf of Mexico to the Atlantic coast.

The terminal's road accessibility is provided by Interstate 35 (I-35) — a federal highway running through Duluth and connecting the city to the Minneapolis-St. Paul metropolitan area to the south and further through Texas to the Mexican border. I-35 is part of the Mid-America Freight Coalition corridor, serving as a key freight artery in the central United States. Vehicle access roads to the Clure Public Marine Terminal allow trucks and container carriers to enter the terminal grounds directly.

Water transport remains the foundation of the port. Lake Superior is connected to the Atlantic Ocean through the Great Lakes system and the St. Lawrence River. Marine vessels deliver containers from European ports — from Rotterdam to Antwerp — to Duluth. The distance of the sea passage from the Atlantic to Duluth is approximately 3,700 kilometers, making the port the farthest from the ocean on the shipping route through the Great Lakes.

Cargo Types Handled at the Terminal

Cargo Connect handles a wide range of commodities. Marine containers are the core of its operations, but far from the only direction. The terminal accepts:

• general cargo and project shipments (equipment, machinery, components for industrial facilities);
• grain cargo — wheat, soybeans, corn from agricultural regions of Minnesota, North and South Dakota;
• lumber and timber products — the forests of Upper Minnesota and Wisconsin provide a steady flow of forest products;
• heavy and oversized cargo — turbines, transformers, infrastructure elements;
• bulk cargo, including limestone and iron ore pellets.

The ability for intermodal transloading — a container from a vessel to a rail platform or onto a truck directly at the terminal — reduces delivery times and lowers handling costs. For grain export, this means that containers delivered with imported goods do not leave empty but are filled with grain for shipment to countries in Asia and Europe. This model improves the efficiency of container fleet utilization and reduces the carbon footprint of transportation.

Terminal Expansion: Plans for the Future

In 2024, Duluth Seaway Port Authority unveiled the Intermodal Terminal Expansion Project — a major project to expand the Cargo Connect terminal. The plan includes increasing areas for container storage and transloading, modernizing loading equipment, and improving access infrastructure.

Terminal development is directly related to the growth of the container market on the Great Lakes. As more shippers consider the route through the Great Lakes as an alternative to congested coastal ports, the need for intermodal capacity in Duluth will only increase. The expansion will also create additional jobs in the port sector and related industries — logistics, equipment repair, and warehousing.

Port authorities view Cargo Connect as a strategic asset not only for the Twin Ports region but for Minnesota's entire transportation system. The terminal is integrated into the Minnesota State Freight Plan, where it is assigned the role of a multimodal hub connecting water, rail, and road transport.

The City of Duluth: Port Heritage and Modernity

Duluth grew as a port city in the second half of the 19th century, when the development of the Mesabi iron ore range began and the first piers on Lake Superior were built. Today, the city combines its industrial heritage with a growing service and tourism economy. The port remains the city's economic backbone — tens of thousands of jobs are directly or indirectly tied to marine and rail transportation.

The city waterfront in the port area is a scenic place. Multi-story buildings, church spires, and water towers create the distinctive silhouette of Duluth, clearly visible from the waterway. The hilly terrain sloping toward the lake makes the port panorama especially striking — the city rises in terraces above the water, with forested hills typical of northern Minnesota visible behind it.

Besides the cargo port, Duluth serves passenger cruises and the yacht fleet. The Duluth Ship Canal connects the inner harbor with the open lake, and the famous Aerial Lift Bridge — a drawbridge over the canal — has become a symbol of the city and simultaneously an important element of road infrastructure. The lifting of the bridge span opens the way for vessels heading to the upper harbor and piers.

Marine Vessels and Tugboats in the Waterway

The waterway of the Port of Duluth-Superior is constantly bustling with activity. Lake bulk carriers (lakers) operate here — specialized vessels designed for transporting bulk cargo across the Great Lakes. Their length reaches 300 meters, and their capacity is tens of thousands of tons. Ocean-going vessels (salties) that arrive via the St. Lawrence River are typically smaller, but they are the ones that deliver marine containers to the Cargo Connect terminal.

Tugboats are an integral part of port life. The dark tugboat with a red superstructure, which often appears in our broadcast, performs maneuvering operations — pushing large vessels away from the pier, accompanying them when entering the harbor, and assisting during mooring. Tugboats in Duluth are operated by several specialized companies and are on 24/7 standby, especially during the navigation season, which lasts roughly from March through January — until ice forms on Lake Superior.

The cargo ship docked at the waterfront in the center of the frame is a typical representative of the container fleet servicing the route through the Great Lakes. Such vessels load and unload containers directly at the Clure Public Marine Terminal pier, after which the containers are shipped by CN rail or truck to their final destinations.
