Highway Freight Must Cross Canada

Trucks can reach Alaska through western Canada using routes that connect with the Alaska Highway. Although the freight may begin and end in the United States, the truck and cargo temporarily enter Canadian territory.

U.S. freight moving through Canada is subject to Canadian reporting and cargo control requirements. Highway carriers may need carrier identification, transit documentation, advance commercial information, and sealed trailers before moving goods between the Canadian border crossings. Canada Border Services Agency rules specifically address U.S. domestic freight that enters Canada before returning to the United States.

The process adds border crossings, documentation, and international compliance to a trip that might otherwise appear domestic. Weather, long distances between services, and conditions along northern highways can further affect transit times.

Much of Alaska’s Freight Arrives by Water

Marine transportation carries a large share of the fuel, food, construction materials, vehicles, and consumer goods shipped into Alaska.

The Don Young Port of Alaska in Anchorage handled approximately 5.5 million tons of fuel and freight in 2025. The port reports that about half of all freight entering Alaska by all transportation modes crosses its docks, including roughly 75 percent of the state’s inbound nonpetroleum marine cargo outside Southeast Alaska.

Cargo arriving in Anchorage does not necessarily stay there. About half of the freight handled by the port continues to destinations outside the city, making Anchorage an important transfer point between ocean carriers, trucking companies, warehouses, retailers, and communities across the state.

Southeast Alaska follows a different pattern because many communities receive barge service directly from the Puget Sound region rather than routing freight through Anchorage. Kodiak and Dutch Harbor also receive regularly scheduled container service.

The Road Network Does Not Reach Every Community

Once freight reaches Alaska, trucks handle much of the movement along the state’s connected highway system. The Port of Alaska estimates that approximately 75 percent of Alaska residents live along roads connected to Anchorage, which makes truck distribution possible across much of Southcentral and Interior Alaska.

Many other communities have no road connection to Anchorage or the national highway network. Freight headed to those locations may require another vessel, a ferry, a smaller barge, or an aircraft after arriving at a major Alaska port.

The Alaska Marine Highway System covers about 3,500 miles of coastline and serves more than 30 communities. Its vessels carry passengers and vehicles ranging from motorcycles to large freight containers, providing an essential surface transportation link for communities that cannot be reached by road.

One Shipment May Use Several Forms of Transportation

A shipment from the Lower 48 may travel by truck to a port in Washington, cross the Gulf of Alaska aboard a cargo vessel, transfer to another truck in Anchorage, and then continue by ferry, barge, or aircraft.

That makes Alaska freight different from a typical interstate shipment. A delay at one point can affect the next connection, particularly when vessels operate on fixed sailing schedules or when weather limits access to remote communities.

Trucking remains central to the system, but it often handles one part of a longer route rather than the entire journey. Trucks connect manufacturers and distribution centers to marine terminals in the Lower 48, move containers away from Alaska ports, and complete deliveries wherever the road system allows.

Frequently Asked Questions

Does Alaska receive most of its freight through Anchorage?

Anchorage is the state’s largest inbound freight hub, but it does not handle every shipment. Southeast Alaska commonly receives direct barge service from Puget Sound, while other ports serve communities such as Kodiak and Dutch Harbor.

How does freight reach communities without road access?

Depending on the destination, freight may continue by ferry, barge, coastal vessel, or aircraft after reaching Alaska.

Can commercial trucks travel on the Alaska Marine Highway?

Alaska Marine Highway vessels are designed to carry vehicles and freight containers, although space, vessel capacity, schedules, and reservation requirements vary by route and sailing.
