Transportation in Alaska

Transportation in Alaska relies on an unusual mix of roads, ferries, rail, aircraft, barges and winter trails because much of the state has no road connection. The road system is small relative to the state’s size, Juneau cannot be reached by road, and many coastal and river communities are reachable only by boat or air. Alaska has about one pilot for every 78 residents, among the highest rates anywhere [1].

Roads

The road network links the central population centers, Fairbanks and the Alaska Highway to Canada. Juneau is not reachable by road. The Anton Anderson Memorial Tunnel connects Whittier to the Seward Highway [1]. See the entry on the Alaska Highway.

Alaska Marine Highway

The state ferry system serves Southeast, Southcentral and the Alaska Peninsula, and runs from Bellingham, Washington, and Prince Rupert, British Columbia, up the Inside Passage to Skagway. The Inter-Island Ferry Authority supplements it in the Prince of Wales Island region [1].

Rail

The Alaska Railroad runs from Seward through Anchorage, Denali and Fairbanks to North Pole, with spurs to Whittier and Palmer. The state bought it from the federal government in 1985, and in 2015 it carried more than 4.3 million tons of freight and about 500,000 passengers a year, mostly seasonal tourists [1][2].

Aviation

The state owns and maintains most airports, and private carriers provide service. In 2000–2001, 1.7 million of 2.4 million visitor arrivals came by air. Lake Hood, next to Ted Stevens Anchorage International Airport, is described as the world’s busiest seaplane base, and about 60 communities receive subsidized Essential Air Service [1]. See the entry on bush aviation.

Ports and Barges

Seward, Whittier and Anchorage serve as rail-linked ports, and barges supply coastal and river communities. Yukon and Tanana river barge service runs only in the ice-free season, sometimes just three or four trips a year to some villages [1].

Winter Trails

The state and boroughs maintain about 4,700 miles of winter trails in the northern and western regions. The Iditarod National Historic Trail covers roughly 2,400 miles from Seward to Nome [1].

Why It Matters

Transportation shapes costs, settlement and culture across the state. Sled dogs, once the main winter transport, are covered in the entry on sled dog mushing in Alaska.
