I-40/US 93 interchange in Kingman now 70% complete

KINGMAN – The Arizona Department of Transportation has entered the final year of work on a project to construct a free-flowing interchange that will reduce delays on the main route between Arizona and Las Vegas.

ADOT has completed about 70% of the project connecting Interstate 40 and US 93 in west Kingman, where the new interchange is expected to open in early 2027. The $106 million improvement means that instead of traffic stopping for a traffic signal on Beale Street at I-40, traffic will be able to flow freely on new ramps.

One of the most visible signs of progress is a large section of the future flyover ramp on I-40 at Clack Canyon. This ramp will carry traffic from southbound US 93 to eastbound I-40. Nearby and mostly out of view, crews have carved and blasted a pathway for one mile of new roadway that will connect I-40 and US 93. Also, tunnels are now complete to carry Beale Street and Fort Beale Drive underneath the new ramps to and from US 93 to I-40.

In the next year, the public can expect to see crews completing the flyover ramp on I-40 at Clack Canyon, paving the connection between I-40 and US 93, constructing new lanes along I-40 and continuing sound wall construction on I-40.

The ongoing construction will continue to involve daytime and nighttime work, including nighttime closures of US 93 for rock blasting. The closures, when needed, will only be scheduled from 8 to 9 p.m. on weeknights. This involves a section of US 93 between the I-40/US 93 interchange and the US 93/State Route 68 interchange.

ADOT is maintaining two lanes of travel in each direction during peak travel times when possible, with lane restrictions limited times when crews need to block a lane for safety. Drivers are able to continue exiting both US 93 and I-40 at Beale Street to access businesses, Route 66 and downtown Kingman.

The completed interchange will open with 6 miles of widened or newly constructed roadway. The project includes two new bridges, two bridge widenings, four bridge rehabilitations and two miles of sound walls. 

The project is creating a mile of new highway carrying traffic northwest of the existing interchange at I-40 and Beale Street. Other features include:

• Widening more than a mile of I-40 in both directions between the new interchange and Stockton Hill Road
• Adding a merge lane on US 93 northbound
• Widening and/or 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

The interchange is designed to handle projected traffic growth for the next 20 years.
