context_page_description: U.S. Route 93 is a major north–south United States highway in the western United States. The southern terminus is at US 60 in Wickenburg, Arizona. The northern terminus is at the Canada–US border north of Eureka in Lincoln County, Montana, where the roadway continues into Roosville, British Columbia, as Highway 93. Major cities that US 93 travels through include: Las Vegas, Nevada; Twin Falls, Idaho; Missoula, Montana; and Kalispell, Montana.
context_section_description: Shortly after entering Idaho at Jackpot, Nevada, US 93 passes US 30 as it enters Twin Falls. North of here, the highway crosses the Snake River Canyon via the Perrine Bridge en route to an interchange with Interstate 84. US 93 passes through Shoshone and runs concurrently with both US 26 and US 20 before reaching Arco. The highway then turns northwest to enter the Big Lost River valley through Mackay.
  Just south of Challis, US 93 becomes the northern leg of the Salmon River Scenic Byway as it heads towards the town of Salmon. From there, the highway follows portions of the Lewis and Clark Trail and passes through the Salmon-Challis National Forest before entering Montana.
