KINGMAN, AZ — The Arizona Department of Transportation (ADOT) has reached the halfway mark on a $106 million project to construct a free-flowing interchange that will reduce delays on the main route between Las Vegas, Nevada, and Arizona.
This milestone comes just 15 months into building a new connection between Interstate 40 and U.S. 93 in west Kingman, Arizona. Instead of traffic stopping for a signal on Beale Street at I-40, 1 mile of new ramps will allow traffic to flow freely between I-40 and U.S. 93.
Some of the most visible progress on the interchange includes building new structures. On I-40 above Clack Canyon, part of a bridge is taking shape that will carry traffic from southbound U.S. 93 to eastbound I-40. Along U.S. 93, tunnels are now in place that will allow future U.S. 93 traffic to pass over Beale Street and Fort Beale Drive.
Earthwork is underway throughout the project area. This includes excavation along southbound U.S. 93 and building up an embankment on I-40 where ramps will connect it to US 93. And on I-40, sound walls are rising on the westbound side between Stockton Hill and White Cliffs roads.
Construction is expected to continue into 2027, when the interchange will open with 6 miles of widened or newly constructed roadway. The project includes five 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
