The James W. Dalton Highway, usually referred to as the Dalton Highway (and signed as Alaska Route 11) is a 414-mile (667 km) 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, and it is labeled as such on Google Maps), 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 13) at Mile 175, 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.
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.
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, and the Roller Coaster. The road reaches its highest altitude as it crosses the Brooks Range at Atigun Pass.
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.
