Alaska is arguably the least-connected state in terms of road transportation. The state’s road system covers a relatively small area of the state, linking the central population centers and the Alaska Highway, the principal route out of the state through Canada. The state capital, Juneau, is not accessible by road, which has spurred several debates over the decades about moving the capital to a city on the road system.

One unique feature of the road system is the Anton Anderson Memorial Tunnel, which links the Seward Highway south of Anchorage with the relatively isolated community of Whittier. The tunnel held the title of the longest road tunnel in North America (at nearly 2.5 miles [4 km]) until completion of the 3.5 mile (5.6km) Interstate 93 tunnel as part of the “Big Dig” project in Boston, Massachusetts.

The Alaska Railroad runs from Seward through Anchorage, Denali, and Fairbanks to North Pole, with spurs to Whittier and Palmer. The railroad is famous for its summertime passenger services but also plays a vital part in moving Alaska’s natural resources, such as coal and gravel, to ports in Anchorage, Whittier and Seward. The Alaska Railroad is the only remaining railroad in North America to use cabooses on its freight trains. A stretch of the track along an area inaccessible by road serves as the only transportation to cabins in the area.

Most cities and villages in the state are accessible only by sea or air. Alaska has a well-developed ferry system, known as the Alaska Marine Highway, which serves the cities of Southeast and the Alaska Peninsula. The system also operates a ferry service from Bellingham, Washington up the Inside Passage to Skagway. Cities not served by road or sea can only be reached by air, accounting for Alaska’s extremely well-developed Bush air services-an Alaskan novelty.

Anchorage itself, and to a lesser extent Fairbanks, are serviced by many major airlines. Air travel is the cheapest and most efficient form of transportation in and out of the state. Anchorage recently completed extensive remodeling and construction at Ted Stevens Anchorage International Airport to help accommodate the upsurge in tourism (unofficial sources have estimated the numbers for 2004 at some four million tourists arriving in Alaska between May and September).

However, regular flights to most villages and towns within the state are commercially challenging to provide. Alaska Airlines is the only major airline offering in-state travel with jet service (sometimes in combination cargo and passenger Boeing 737-200s) from Anchorage and Fairbanks to regional hubs like Bethel, Nome, Kotzebue, Dillingham, Kodiak, and other larger communities as well as to major Southeast and Alaska Peninsula communities. The bulk of remaining commercial flight offerings come from small regional commuter airlines like: Era Aviation, PenAir, and Frontier Flying Service. The smallest towns and villages must rely on scheduled or chartered Bush flying services using general aviation aircraft such as the Cessna Caravan, the most popular aircraft in use in the state. Much of this service can be attributed to the Alaska bypass mail program which subsidizes bulk mail delivery to Alaskan rural communities.

The program requires 70% of that subsidy to go to carriers who offer passenger service to the communities. But perhaps the most quintessentially Alaskan plane is the Bush seaplane. The world’s busiest seaplane base is Lake Hood, located next to Ted Stevens Anchorage International Airport, where flights bound for remote villages without an airstrip carry passengers, cargo, and lots of items from stores and warehouse clubs.

Another Alaskan transportation method is the dogsled. In modern times, dog mushing is more of a sport than a true means of transportation. Various races are held around the state, but the best known is the Iditarod, a 1,150-mile (1850 km) trail from Anchorage to Nome. The race commemorates the famous 1925 serum run to Nome in which mushers and dogs like Balto took much-needed medicine to the diphtheria-stricken community of Nome when all other means of transportation had failed. Mushers from all over the world come to Anchorage each March to compete for cash prizes and prestige.a
