The Top of the World Highway is a long highway, beginning at a junction with the Taylor Highway near Jack Wade, Alaska traveling east to its terminus at the ferry terminal in West Dawson, Yukon, on the western banks of the Yukon River. The highway has been in existence since at least 1955 and is only open during the summer months. The entire portion of the highway in Yukon is also known as Yukon Highway 9. The Alaska portion is short and apparently not numbered. The Alaska Department of Transportation refers to it as Top of the World Highway.〔(Alaska DOT, Taylor and Top of the World Highways )〕 As of July 2014, the US portion of the highway is paved, and most of the Canadian portion is unpaved. The paved Canadian sections are from kilometer 0 (at Dawson) to 9, 74 to 76, 79 to 82, 83 to 94 and 99 to 104 (at the Canada-US border). The highway is so named because, along much of its length, it skirts the crest of the hills, giving looks down on the valleys. It is also one of the most northerly highways in the world at those latitudes. Two nearby, farther north highways are the Dempster Highway (Yukon Route 5) and the Dalton Highway (Alaska Route 11). It is not particularly safe in winter, even for snowmobile use, due to the lack of trees for shelter. A ferry connects West Dawson to Dawson in summer,〔 and residents living in West Dawson and nearby Sunnydale cross on the ice during the winter. A bridge is planned by the Yukon government, although there is significant division among Dawson area residents as to whether such a bridge should be built. The west-bank residents received improved phone service only in 2004 but do not have a public electricity supply. A 50 kilometre branch road off the highway was used to reach the town of Clinton Creek, Yukon, site of a former asbestos mine shut down since 1979. The Poker Creek - Little Gold Creek Border Crossing features one of the few jointly-built single building customs ports of entry along the Canada-U.S. border. There is a one-hour difference in standard time zones at this border, which is only open in summer during the 8 a.m. to 8 p.m. period (Alaska time). The immense Alaskan Taylor Complex Fire of 2004 burned up to the Canadian border and was visible from the westernmost portions of the highway. ==References== http://www.topoftheworlds.com/the-top-of-the-world-highway/ 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「Top of the World Highway」の詳細全文を読む スポンサード リンク
