U.S. Highway 93
United States Highway 93 is a major north-south United States highway in the western U.S., extending between the Canadian border in Montana, where it connects with B.C. Highway 93, and Wickenburg, Arizona, a small town about 50 miles (80 km) northwest of Phoenix.
Major cities that U.S. Highway 93 travels through include Missoula, Montana, Twin Falls, Idaho, and Las Vegas, Nevada.
Popular bumper sticker often seen in Montana: "Pray for me, I drive Hwy 93!"

Termini
As of 2004, the highway's northern terminus is in Lincoln County, Montana at the Canadian border, where it continues as Provincial Highway 93. Its southern terminus is in Wickenburg, Arizona at an intersection with U.S. Highway 60.
Historic Termini
Until 1993, US 93 ended a short distance north of Wickenburg, Arizona at a junction with U.S. Highway 89. When US 89 was decommissioned in the area, the US 93 designation was carried on into Wickenburg.
Projected Upgrades
US 93 (with US 60 to the southeast of Wickenburg) is the shortest route between the fast-growing cities of Las Vegas and Phoenix, two of the largest cities in America. Upgrades of US 60 and US 93 to freeway status are scheduled between Las Vegas and Phoenix, after which US 93 will probably be decommissioned south of its northern junction with Interstate 15 to the northeast of Las Vegas in favor of Interstate 15 and some new Interstate highway (designation unknown -- 11? 13?).
A segment of the new highway is in the very early stages of construction (in 2004) in the area of Hoover Dam; the expressway, which will include tunnels that will replace a highway now closed to truck traffic due to its inadequacy (the mountain road includes switchback curves and concerns of the security of the dam itself since the September 11, 2001 attacks. It will incorporate the now-complete Interstate 515 through Las Vegas and it will make unnecessary the truck detour through either Laughlin, Nevada or Needles, California.

Alternate Routes
As of 2004, Alternate US 93 has a northern terminus at Wells, Nevada. It rejoins US 93 at an intersection called "Lages Station" in northern White Pine County, Nevada. While the main line of US 93 is the direct route from Lages Station to Wells, Alt US 93 provides a shortcut to eastbound Interstate 80 and Salt Lake City, Utah.
Until the 1970s, an alternate route also existed in Idaho.
