The James W. Dalton Highway, usually referred to as the Dalton Highway (and signed as Alaska Route 11), is a 〔(【引用サイトリンク】title=Dalton Highway )〕 road in Alaska. It begins at the Elliott Highway, north of Fairbanks, and ends at Deadhorse near the Arctic Ocean and the Prudhoe Bay oil fields. Once called the North Slope Haul Road (a name by which it is still sometimes known), it was built as a supply road to support the Trans-Alaska Pipeline System in 1974. It is named after James Dalton, a lifelong Alaskan and an engineer who supervised construction of the Distant Early Warning Line in Alaska and, as an expert in Arctic engineering, served as a consultant in early oil exploration in northern Alaska. ==Route description== The highway, which directly parallels the pipeline, is one of the most isolated roads in the United States. There are only three towns along the route: Coldfoot (pop 10) at Mile 175,〔2008 edition of The Milepost, pp. 517-529 (Morris Communications Company)〕 Wiseman (pop 22) at Mile 188,〔 and Deadhorse (25 permanent residents, 3,500-5,000 or more seasonal residents depending on oil production) at the end of the highway at Mile 414.〔 Fuel is available at the E. L. Patton Yukon River Bridge (Mile 56), as well as Coldfoot and Deadhorse.〔 Two other settlements, Prospect Creek and Galbraith Lake, are uninhabited except for seasonal residents. The road itself is very primitive in places, and small vehicle and motorcycle traffic carries significant risk. The nearest medical facilities are in Fairbanks and Deadhorse. Anyone embarking on a journey on the Dalton is encouraged to bring survival gear. Despite its remoteness the Dalton Highway carries a good amount of truck traffic: about 160 trucks daily in the summer months and 250 trucks daily in the winter.〔 The highway comes to within a few miles of the Arctic Ocean. Beyond the highway's terminus at Deadhorse are private roads owned by oil companies, which are restricted to authorized vehicles only. There are, however, commercial tours that take people to the Arctic Ocean. All vehicles must take extreme precaution when driving on the road, and drive with headlights on at all times. There are quite a few steep grades (up to 12%) along the route, as well. As of July 2013, of the highway are paved, in several sections, between the following mileages: 19 and 24; 37 and 50; 91 and 111; 113 and 197; 257 and 261; 344 and 352; and 356 and 361. Truckers on the Dalton have given their own names to its various features, including: The Taps, The Shelf, The Bluffs, Oil Spill hill, Beaver Slide, Two and a Half Mile, Oh Shit Corner,〔(Oh Shit Corner )〕 and the Roller Coaster. The road reaches its highest altitude as it crosses the Brooks Range at Atigun Pass, 4,739 feet (1,444 m). The highway is the featured road on the third, fourth, fifth and sixth seasons of the History reality television series ''Ice Road Truckers'', which aired May 31, 2009 to present. It is also the subject of the second episode of ''America's Toughest Jobs'' and the first episode of the BBC's ''World's Most Dangerous Roads'' featuring Charley Boorman and Sue Perkins. Google Street View has coverage of nearly the entire highway, which can now be seen on Google Maps (imaging stops at the security gate leading to the Prudhoe Bay oil field). It is one of the most northerly routes of Google street view in North America. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dalton Highway」の詳細全文を読む スポンサード リンク
