I-40/US 93 Kingman interchange project set to begin in the new year

KINGMAN – The new year will be an exciting one for drivers who use US 93 between the Phoenix area and Kingman as the Arizona Department of Transportation advances one major project to increase capacity and starts another.

A current US 93 widening project near Wickenburg is at 50% completion. And by summer, one of the largest US 93 improvement projects in recent years will kick off in west Kingman as work starts to construct an interchange that will provide a free-flowing connection between US 93 and Interstate 40.

These US 93 projects are among many projects ADOT plans to start, continue or complete across northern Arizona in 2024.

The Kingman interchange is planned to eliminate delays that can occur for passenger and truck traffic on the main route between Las Vegas and Arizona. While traffic now must stop at a traffic signal where Beale Street intersects with I-40, a system-to-system interchange features ramps that allow traffic to flow freely.

This interchange, expected to open in 2026, is designed to handle projected traffic growth for the next 25 years. For more information on the Kingman interchange project, please visit azdot.gov/WestKingmanTI. 

The current US 93 project near Wickenburg is now halfway done as work continues to transform a 5-mile section of two-lane roadway into a four-lane divided highway. Work on the Wickenburg-area project is expected to continue through 2024, with lane restrictions limited to overnight hours to minimize traffic impacts. More information is available at azdot.gov/US93Wickenburg. 

Since 1999, ADOT has completed 19 projects to modernize US 93 between Wickenburg and I-40. ADOT's long-term vision calls for four-lane divided highway through the entire 200 miles between Wickenburg and Nevada. 

More projects are scheduled to be under construction on US 93 over the next several years as ADOT continues working on turning its vision into reality.

ADOT’s Five-Year Transportation Facilities Construction Program for 2024-2028 has these additional projects scheduled to convert US 93 to four-lane divided highway:

• Fiscal 2024: Mileposts 106-109.5.in the Cane Springs area
• Fiscal 2026: Mileposts 190.5-193.5 in the Vista Royale area northwest of Wickenburg
• Fiscal 2027: Mileposts 161.7-166.2 in the area of Big Jim Wash

Another project scheduled to start in 2026 calls for adding passing lanes to US 93 between mileposts 171.5-173 and 175.5-177.

In addition to US 93, ADOT is planning to begin, continue or complete several major projects improving travel to, from and within northern Arizona in 2024, including:

• Continuing work to rehabilitate pavement and bridges on a 29-mile stretch of southbound I-17 between Flagstaff and the Coconino County line. Work on this heavily traveled highway began in spring 2022 and will continue through fall 2024. For more information, please visit azdot.gov/I-17Southbound.
• Beginning work next summer to widen 1 mile of SR 69 in Prescott. ADOT, working with the Central Yavapai Metropolitan Planning Organization, will add a third lane of travel in each direction of the highway between Prescott Lakes Parkway and Yavpe Connector with a raised center median. The project, which will improve safety and increase roadway capacity, will be complete by mid-2024. For more information please visit azdot.gov/sr69frontiervillage.
• Continuing the $56 million Interstate 15 Bridge No. 1 replacement project near Littlefield in northwestern Arizona, with completion scheduled by spring 2024. The challenging project in the Virgin River Gorge provides a safer I-15 bridge operating with two lanes in each direction. Work began in February 2021. For more information, please visit azdot.gov/I-15VirginRiverBridge.
• Beginning work to replace the Queen Creek and Waterfall Canyon bridges on US 60 just east of Superior. The project, similar to a nearby project that replaced the Pinto Creek Bridge, will require a series of daytime highway closures for rock blasting operations. The project will begin in early 2024 and is scheduled to take three years. For more information, please visit azdot.gov/US60QueenCreekBridgeProject.
• Completing two paving projects on SR 95 totalling 49 miles, covering a 23-mile section between I-40 and SR 28 and a 26-mile segment between I-40 and Lake Havasu City. Work began in 2023 on both projects and is expected to be completed in early 2024. 
• Beginning work to rehabilitate the SR 87 Coyote Wash bridge about 25 miles north of Winslow, at milepost 375.
• Continuing a major I-17 improvement project north of the Phoenix area to improve safety and efficiency on 23 miles of one of Arizona’s busiest corridors. The work includes 8 miles of flex lanes that can carry traffic northbound or southbound, depending on which direction is carrying the most traffic at any given time, between Black Canyon City and Sunset Point. Also, ADOT is constructing a third traffic lane on 15 miles of I-17 between Anthem and Black Canyon City. The project is expected to be complete in 2025.
