Arizona
US 93 begins at US 60 in Wickenburg, a small town approximately northwest of Phoenix. northwest of Wickenburg, US 93 passes through a large forest of Joshua trees and is thus labeled the Joshua Forest Parkway of Arizona until it reaches Wikieup.
From there, it heads north, eventually merging with Interstate 40 (I‑40) to head west to Kingman. US 93 then splits from I‑40 in Kingman and heads north to the Hoover Dam. Chloride is located off this highway, and Santa Claus is on the western side, about before the Chloride Road intersection.
This highway was known to be one of the deadliest routes in America until recently. The years of improvements have made it a much safer road to travel, according to the Federal Highway Administration.
Nevada
US 93 enters Nevada where Interstate 11 (I‑11) currently begins: on the Hoover Dam Bypass. I‑11 / US 93 then winds its way west-southwest through Boulder City before merging with U.S. Route 95 (US 95) past the interchange with Nevada State Route 173. These three routes (I‑11 / US 93 / US 95) then curve northwest toward Las Vegas. Upon reaching the southern end of Interstate 515 (I‑515) and the northern end of I‑11 in Henderson, US 93 / US 95 then run concurrent I‑515 through Henderson and southeastern Las Vegas, where US 93 exits at the Las Vegas Spaghetti Bowl interchange just northwest of downtown, heading northbound concurrently with Interstate 15 (I#8209;15). Those two routes then run in a northeasterly direction through North Las Vegas until they exit the metro area, where US 93 diverges from I‑15 at Apex to head north toward Great Basin National Park. Near there, the highway joins with the combined US Routes U.S. Route 6 / U.S. Route 50 (US 6 / US 50) to run northwest toward Ely. In Ely, US 6 first departs and heads west toward Tonopah. Then, shortly thereafter, US 50 departs US 93 to continue west toward Fallon and Reno (via U.S. Route 50 Alternate west, U.S. Route 95 Alternate north, and Interstate 80 [I‑80] west) and Carson City. Upon reaching Lages Station, U.S. Route 93 Alternate (US 93 Alt) splits off in a northeasterly direction toward West Wendover. The main route of US 93 continues north from Lages Station, intersecting I‑80 at Wells before crossing the Idaho state line on the north edge of Jackpot.
Between State Route 318 and Majors Junction (US 6 / US 50), US 93 is designated a Nevada Scenic Byway. From Ely to Schellbourne Ranch, US 93 is part of the Lincoln Highway, the first road across the United States.
Idaho
Shortly after entering Idaho, US 93 crosses U.S. Route 30 as it before running through the northern edge Twin Falls. North of here, the highway crosses the Snake River Canyon via the Perrine Bridge enroute to an interchange with Interstate 84. US 93 passes through Shoshone and runs concurrently with U.S. Route 20 / U.S. Route 26 (US 20 / US 26) before reaching Arco. The highway then turns northwest (leaving US 20 / US 26) 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 toward 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.
Montana
US 93 enters Montana from Idaho at Lost Trail Pass and travels north descending through the Bitterroot National Forest. The highway continues along the Lewis and Clark Trail into the Bitterroot Valley towards Missoula, passing through Darby and Hamilton. At Lolo, U.S. Route 12 (US 12) joins from the west and they run concurrently northeast for , where US 93 heads due north on Reserve Street in Missoula. US 93 then joins Interstate 90 (I‑90) and runs concurrently westward for to Wye, where it heads north.
