The Alaska Marine Highway System operates along the southcentral coast of the state, the eastern Aleutian islands and the Inside Passage of Alaska and British Columbia, Canada. Ferries serve communities in Southeastern Alaska that have no road access, and the vessels can transport people, freight, and vehicles. AMHS's 3,500 miles of routes go as far south as Bellingham, Washington in the contiguous United States and as far west as Unalaska/Dutch Harbor, with a total of 32 terminals throughout Alaska, British Columbia, and Washington. It is part of the National Highway System and receives federal highway funding. It is also a form of transportation of vehicles between the state and the contiguous United States without going through Canada.
The Alaska Marine Highway System is a rare example (in the USA) of a shipping line offering regularly scheduled service for the primary purpose of transportation rather than of leisure or entertainment. Voyages can last many days, but, in contrast to the luxury of a typical cruise line, cabins cost extra, and most food is served cafeteria-style.
In September 2005, the Alaska Marine Highway was named an All-American Road by the Federal Highway Administration.
The Alaska Marine Highway's main hub is in Juneau, though administrative offices were recently and controversially moved to Ketchikan. Other smaller operational hubs include Cordova (Prince William Sound), Ketchikan (southern Panhandle), and Kodiak (Southcentral Alaska).
The AMHS serves the following communities year-round: Akutan; Angoon; Bellingham, Washington; Chenega Bay; Chignik; Cold Bay; Cordova; False Pass; Haines; Homer; Hoonah; Juneau; Kake; Ketchikan; King Cove; Kodiak; Metlakatla; Petersburg; Port Lions; Prince Rupert, British Columbia; Sand Point; Seldovia; Sitka; Skagway; Tatitlek; Tenakee Springs; Unalaska/Dutch Harbor; Valdez; Whittier; Wrangell; and Yakutat. Bartlett Cove, location of the Glacier Bay National Park ranger station and eight miles (13 km) from the community of Gustavus, is served occasionally by the M/V LeConte in summer months.
Most Alaska Marine Highway System vessels are built for multiple-day voyages due to the large distances between ports. For example, it takes just under three days to travel from Bellingham to Skagway, and 18 hours for the Sitka to Juneau "milk run." Because of this, larger vessels (M/V Tustumena and larger) come with staterooms, while all mainline vessels have solariums, showers, and lounges for sleeping. Hot food services and, on the M/V Columbia, a sit-down restaurant are also offered.
All current vessels are named after Alaskan glaciers.
The ferry system has been in the spotlight in recent years over a proposal to build a road link between Skagway and Juneau, the only mainland state capital in the United States without road access. Proponents of the road have called ferry service spotty and expensive compared to roads and say residents should be able to come and go as they please. Critics say the very people who want the road, the administration of Governor Frank Murkowski, are also in charge of the ferry system and are themselves responsible for the "spotty" ferry service and service changes often considered illogical. As well as the possibility for improved commerce and improved capital access, a road would present significant environmental, financial and social concerns that must be addressed.
