U.S. Route 93 Corridor Projects

ADOT has dedicated nearly half a billion dollars to widening and improving US 93 from Wickenburg to Hoover Dam over the last several years. ADOT's long-term vision is to transform this highly traveled route into a four-lane divided highway through the entire 200-mile stretch. The US 93 series of projects is a priority for ADOT and has significantly improved our state highway system to move people, goods and services more efficiently.

Current Projects

US 93: Tegner Street – State Route 89

The Arizona Department of Transportation in conjunction with the Federal Highway Administration is planning to improve the safety and traffic operations on US 93 from State Route 89 (milepost 193) to the Wickenburg Interim Bypass (milepost 198) in Wickenburg.

The project will consist of the following:

  • Widening US 93 to two lanes in each direction in the project area
  • Constructing raised center medians
  • Constructing access frontage roads
  • Constructing roundabouts at Rincon, Cope and Vulture Mine and Scenic Loop roads, and at State Route 89

The project straddles a county line, with about 30 percent in Maricopa County and the remaining 70 percent in Yavapai County.

Construction is scheduled to begin in 2021.

Completed Projects

US 93 North of Interstate 40

Kingman to Hoover Dam (milepost 2 to 17)

In November 2010, ADOT completed construction on the final 15 miles of roadway south of the Hoover Dam, providing motorists with a continuous four-lane divided highway on Interstate 40 between Kingman and the new Hoover Dam Bridge.

Project construction included widening an existing 15-mile roadway section, and providing significant highway improvements. The $71.3 million lane widening project includes a new trailhead at milepost 4.1, and a new scenic overlook at milepost 13.5. The existing overlook (milepost 12.7) has also been upgraded. Three wildlife crossings over US 93 were constructed at mileposts 3.3, 5.2, and 12.2 to protect motorists and provide a safe crossing for the Desert Bighorn Sheep, native to the Black Mountains.

US 93 Pavement Preservation Project from State Route 89 to Rincon Road

The Arizona Department of Transportation completed work on a five-mile repaving project in May 2017,on US 93 between State Route 89 and Rincon Road (mileposts 193 to 198) in Wickenburg.

This $1.9 million project consisted of new rubberized asphalt, guardrail replacements, new striping and other miscellaneous work.

US 93 South of Interstate 40

The first segment on South US 93, spanning 36 miles between Wikieup and Santa Maria was completed in February 2008. This section of the highway was divided into 9 different projects. It included widening the highway to four lanes and building two bridges one at Burro Creek and the other at the Santa Maria River.

Southbound Wagon Bow Ranch and Southbound Deluge Wash

Construction to widen and improve a seven-mile segment of US 93 north of Wikieup (milepost 109 to 116.3) was completed in July 2012. The $26 million project provides motorists with new southbound lanes and another completed section of four-lane divided highway.

Wikieup to Interstate 40

ADOT has completed 4 widening projects between Wikieup and I-40. Construction on the Southbound Ranch Road project, located 17 miles north of Wikieup (milepost 104 to 106), was completed in late 2009. The $5.8 million lane widening project, funded by the American Recovery and Reinvestment Act, provides two additional miles of four-lane divided highway.

McGarry's Wash

Construction on US 93 at McGarry's Wash, located just south of the I-40/US 93 traffic interchange (milepost 91.7 to 95.2), was completed in October 2008. The $9.8 million project consisted of constructing a parallel roadway to create a four-lane divided highway.

Old US 93 to Antelope Wash

The $20 million four lane widening project from old US 93 to Antelope Wash (milepost 91.4 to 101.9) was completed in January 2007.

Tompkins Canyon

Construction north of Wikieup near Tompkins Canyon (mile post 119.5 to 121.2) consisted of parallel roadway to create a four-lane divided highway. The $10.6 million project was completed in November 2008.

US 93 Wickenburg Bypass

In February 2010, ADOT completed the Wickenburg Interim Bypass which has relieved the congestion at the intersection of US 93 and US 60 in downtown Wickenburg. The $30 million project included constructing a four-lane divided highway, two roundabouts and a new bridge.

Remaining highway improvement projects include

  • Carrow Stephens, milepost 116.3 to 119.7 (construction funding programmed for fiscal year 2016)*
  • Cane Springs, milepost 106 to 108.9 (pending construction funding)
  • Wickenburg Interim Bypass and SR 89, milepost 193 to 198 (construction currently unfunded; construction schedule to be based on funding availability and statewide priorities)

The segment between Wickenburg and the Santa Maria River will be the last to be improved. The construction scheduled will depend on statewide priorities and available funding.

* Project schedules can change based on available funding and statewide priorities.

Future Projects

Remaining highway improvement projects include

  • Carrow Stephens, milepost 116.3 to 119.7 (construction funding programmed for fiscal year 2021)
