U.S. Route 50 (US-50) in Utah crosses the center of the state. The highway serves no major population centers in Utah, with the largest city along its path being Delta. Most of the route passes through desolate, remote areas. Through the eastern half of the state the route is concurrent with Interstate 70 (I-70). US-50 both enters and exits Utah concurrent with US-6, however the two routes are separate through the center of the state. Three completely different routings of US-50 have existed between Green River and Ely, Nevada. The route between these cities has become progressively shorter as new roads have been paved through this largely uninhabited region of both states. The earlier routings were a result of a dispute between Utah and Nevada over which auto trails would be paved and converted to U.S. Highways. ==Route description== The highway enters Utah from Nevada in a desolate portion of the Great Basin desert. Similar to many portions of the route in Nevada, there are no services from this point to Delta, a span of roadway that is about .〔 While passing through the Great Basin the highway crosses two mountain ranges, the Confusion Range via kings canyon and House Range via Skull Rock Pass, before arriving at the shore of Sevier Lake. Sevier Lake is an intermittent lake which is fed by snow melt from many mountain ranges in the eastern half of the Great Basin. From US-50, water is only usually visible in the spring months. The highway follows Sevier Lake to Delta. The scenery dramatically changes as US-50 approaches Delta, where U.S. Route 6 and 50 separate. As the road approaches Delta, a straight passage across desert changes to zigzags through farming areas. The highway continues to zigzag through farms until arriving at more mountainous terrain at Holden. At Holden, the highway merges with Interstate 15 to cross the Pavant Range at Scipio Summit. US-50 then separates from this freeway to meet Interstate 70 in Salina. The two highways run concurrent from this point east to Colorado. Yet again, there is a stretch of highway long without services from Salina to Green River.〔 While co-routed with I-70, US-50 crosses the Wasatch Plateau and passes through the San Rafael Swell. The construction of I-70 through the swell is noted as one of the engineering marvels of the Interstate Highway System. One specific feat, the excavation through a portion called Spotted Wolf Canyon, required excavating of rock to have a bed for just of roadway. Construction workers noted that prior to the construction of the freeway a man could stand in this canyon and touch both sides of the canyon wall. US-6 rejoins US-50 near Green River. The three routes run concurrent and follow the southern edge of the Book Cliffs to Grand Junction, Colorado. Once again, services are not present from Thompson Springs to Fruita, Colorado, a span of about .〔 This portion of US-50 is part of the Dinosaur Diamond Prehistoric Highway, a National Scenic Byway. The name of the byway comes from the large number of areas along the route with visible dinosaur remains.〔(【引用サイトリンク】title= Dinosaur Diamond Prehistoric 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「U.S. Route 50 in Utah」の詳細全文を読む スポンサード リンク
