WICKENBURG, AZ – The Arizona Department of Transportation will begin a project to improve safety along US 93 north of Wickenburg by installing centerline rumble strips along a 20-mile section of the highway.

The project area stretches from the Santa Maria River to the junction with State Route 71, which is mileposts 161 to 183. The work will take place overnights from 9 p.m. to 5 a.m. beginning Monday, July 18, and lasting through early August. No weekend work is scheduled.

US 93 will be narrowed to one lane only in 2-mile segments while crews work. A flagging operation and pilot car will guide motorists through the work zone. Drivers should expect delays of up to 20 minutes.

The $545,000 project is designed to improve safety along this two-lane stretch of US 93 by helping to reduce the frequency and severity of lane and road-departure crashes.

The project also includes the replacement of raised pavement markers, new striping and crack seal repair of the road.

ADOT has dedicated nearly half a billion dollars to widening and improving US 93 in this region over the last decade. ADOT's long-term vision is to transform this highly traveled route into a four-lane divided highway. Of the 200-mile drive from Wickenburg to the Hoover Dam, approximately 35 miles remain to be widened.

A project to widen US 93 in Wickenburg from Tegner Street to Wickenburg Ranch Way is currently being advertised and anticipated to start early next year. ADOT has also applied for a grant through the federal Infrastructure Investment and Jobs Act to help accelerate the widening of three additional segments of US 93.

The Arizona Department of Transportation submitted a competitive grant bid that, if awarded, would allocate approximately $65 million to speed up already-planned improvement projects on US 93 between Wickenburg and Interstate 40. 

If the grant application is approved, these competitive funds would be added to state match funding and additional federal dollars, for a potential total of more than $200 million for the improvements on US 93, in partnership with the Federal Highway Administration. 

The prospective funding and work would come from an Infrastructure for Rebuilding America (INFRA) grant through the federal Infrastructure Investment and Jobs Act (IIJA). It would complement work already completed by ADOT, improving safety and removing existing bottlenecks along a major route between Phoenix and Las Vegas. 

The projects include a three-mile stretch of the highway near Cane Springs, four and a half miles near Big Jim Wash and three miles near Vista Royale. Together, these three projects will widen more than 10 miles of US 93 to a four-lane divided highway. Currently, fewer than 40 miles of US 93 between Wickenburg and I-40 remain a two-lane highway.

ADOT has dedicated nearly half a billion dollars to widening and improving US 93 in this region over the last several years. ADOT's long-term vision is to transform this highly traveled route into a four-lane divided highway. 

Improvements to these three segments will enhance safety and further prepare Arizona and the region for increased population growth, as well as economic and freight activity. US 93 between Wickenburg and Kingman is designated as the Future Interstate 11. With the grant, ADOT will improve project delivery through accelerated construction techniques delivering the improvements earlier than traditionally available.

KINGMAN – As construction season in northern Arizona resumes, three bridges in the northwestern part of Arizona will be rehabilitated starting this year.

Along Interstate 40, ADOT will reconstruct the bridge decks on the bridge at Exit 123 into the east side of Seligman. The project is needed to replace the damaged elements of the bridges and to perform other upgrades to increase the lifespan of the bridges.

Crews will be replacing the bridge decks of the two bridges as well as the approaches, and any guardrails and curbs as needed. During the project, traffic will be shifted over to share one side of I-40 with one lane in each direction through the work zone. Access to all adjacent properties will be maintained during daytime hours.

Also along I-40, the overpass for Anvil Rock Road, located about 11 miles west of Seligman, will receive a new bridge deck. Work will occur during the day from 6 a.m. to 6 p.m. Sundays through Thursdays. Drivers along I-40 can expect the highway to be intermittently reduced to one lane as work requires. There will also be a full closure of I-40 when demolition of the bridge deck takes place. Traffic will be rerouted around the closure using the off- and on-ramps at the Anvil Rock Road exit. 

On US 93 south of I-40, ADOT will begin rehabilitation of the Kabba Wash Bridge at milepost 97 north of Wikieup on Monday, April 11. This project will include widening the existing northbound bridge, replacing the existing bridge deck and approach slabs, guardrail work, and installing new pavement markings. Northbound US 93 will be reduced to one lane in the work zone for the duration of the project.

Construction for the bridges at Exit 123 and Kabba Wash is anticipated to be completed in late 2023. The Anvil Rock Road overpass is anticipated to be completed by this fall.

PHOENIX – The Arizona Department of Transportation has finished converting three miles of US 93 north of Wikieup to a four-lane divided highway increasing safety and traffic capacity.

The upgrade to a four-lane divided highway improves traffic flow, supports the movement of freight and enhances safety through this heavily traveled corridor.

This project connects two sections of highway that had already been widened. This provides a continuous stretch of divided four-lane highway from milepost 108, about 15 miles south of I-40, and milepost 121 near Wikieup.

The majority of the 200-mile drive from Wickenburg to the Nevada state line has been widened. Fewer than 40 miles of US 93 remain a two-lane highway.

Work on the $35 million project began in the spring of 2019. In addition to converting US 93 into a four-lane divided highway, the project included building concrete box culverts, two box bridges and installing pipe culverts, guardrail and fencing. 

Crews plan to return in the spring to add a top layer of pavement, known as friction course, to the newly-widened segment.

PHOENIX – With the completion of new lanes for the US 93 widening project north of Wikieup, the Arizona Department of Transportation will conduct a traffic switch Monday, Sept. 21 so crews can work on rebuilding the existing southbound lanes.

The traffic switch will occur at 8 a.m. Monday, Sept. 21, between mileposts 116 and 119. Drivers in the area should expect a brief delay while crews switch all traffic to the new northbound lanes.

The upgrade to a four-lane divided highway improves traffic flow, supports the movement of freight and enhances safety through this heavily traveled corridor.

Work on the project began in the spring of 2019. In addition to converting US 93 into a four-lane divided highway, the project includes building concrete box culverts, two box bridges and installing pipe culverts, guardrail and fencing.

The new section of 3-mile divided highway is expected to be completed in the fall.

PHOENIX – Travelers driving between Kingman and Wickenburg will need to plan extra travel time as the Arizona Department of Transportation will be conducting pavement maintenance work on US 93 south of Wikieup from Monday, Aug. 31 through Thursday, Sept. 3.

Work will take place from 5 a.m. to 6 p.m. daily between the Santa Maria Bridge and Alamo Road, which includes mileposts 162 to 180. US 93 will be narrowed to one lane with flaggers and a pilot car leading traffic through the work zone. Crews will only be working in sections of a few miles a day.

Drivers should expect delays of about 20 minutes and move slowly through the work zone.

Workers will be doing pavement maintenance work again on Tuesday, Sept. 8 from 5 a.m. to 6 p.m. between Alamo Road and the State Route 71 junction. US 93 will be narrowed to one lane in that area with a flagging operation to guide traffic through the work zone.

Crews will be placing a sealant on the existing asphalt, which helps protect and extend the life of the roadway.

PHOENIX – The Arizona Department of Transportation has been granted environmental approval to move forward with plans to improve the US 93/I-40 traffic interchange in west Kingman.

ADOT issued a Finding of No Significant Impact after completing a Final Environmental Assessment for the project, which was prepared in compliance with the National Environmental Policy Act. The Final Environmental Assessment includes comments from the community received through the public hearing on May 28, 2020. The document is posted at azdot.gov/WestKingmanTIP.

The improvements to the traffic interchange include a free-flowing direct connection between US 93 and I-40, designed to reduce congestion and improve traffic flow. Currently, traffic switching between the highways must stop at an intersection with a traffic signal before proceeding.

The new traffic interchange is designed to accommodate both current and projected traffic volumes for this area for the next 25 years.
