KINGMAN, AZ — The Arizona Department of Transportation (ADOT) 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, Nevada.
ADOT has completed about 70 percent of the project connecting Interstate 40 and U.S. 93 in west Kingman, Arizona, 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 U.S. 93 to eastbound I-40. Nearby and mostly out of view, crews have carved and blasted a pathway for 1 mile of new roadway that will connect I-40 and U.S. 93. Also, tunnels are now complete to carry Beale Street and Fort Beale Drive underneath the new ramps to and from U.S. 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 U.S. 93, constructing new lanes along I-40, and continuing sound wall construction on I-40.
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 2 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 U.S. 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.
