ADOT continues work on Interstate 40, US 93 Kingman interchange

PHOENIX — The Arizona Department of Transportation is continuing its work on an interchange project connecting U.S. Route 93 and Interstate 40 in Kingman, according to a news release.

ADOT provided an update on Thursday and said crews have cleared land for new travel lanes, removed sound walls and are preparing work for new bridges.

The $106 million project began back in July with the goal to eliminate delays for drivers on the main route between Las Vegas and Arizona. 

The project includes five new bridges, two bridge widenings, four bridge rehabilitations and two miles of sound walls. Other project features include:

• Widening more than one mile of I-40 in both directions between the new I-40/US 93 interchange and Stockton Hill Road
• A merge lane on US 93 northbound
• Widening/rehabilitating four bridges on I-40
• Building sound walls along a portion of I-40 to the west of Stockton Hill Road
• Constructing drainage features

ADOT is maintaining two lanes of travel in each direction during peak travel times, with lane restrictions limited to off-peak hours.

The project is expected to continue into 2027. ADOT said the public can expect work during the day and at night and that small closures of the US 93 will occur for rock blasting. 

ADOT says drivers can exit the US 93 and I-40 at Beale Street to access businesses, the Route 66 highway and downtown Kingman.
