The Arizona Department of Transportation announced on Mar. 30 that construction on the I-40 and US 93 interchange in west Kingman is now about 70 percent complete, with the new free-flowing interchange expected to open in early 2027.
The project aims to reduce traffic delays along a key route between Arizona and Las Vegas by replacing the current traffic signal at Beale Street with ramps allowing continuous movement. This $106 million initiative is intended to improve safety and efficiency for travelers, supporting both local commuters and long-distance drivers.
One significant milestone is the installation of a large section of the future flyover ramp on I-40 at Clack Canyon, which will direct southbound US 93 traffic onto eastbound I-40. Crews have also finished tunnels under the new ramps for Beale Street and Fort Beale Drive, while ongoing work includes paving connections between highways, constructing additional lanes along I-40, and building sound walls. Daytime and nighttime construction continues, including occasional nighttime closures of US 93 for rock blasting from 8 to 9 p.m. on weeknights.
The completed interchange will feature six miles of widened or newly built roadway, two new bridges, four bridge rehabilitations or widenings, two miles of sound walls, drainage improvements, an added merge lane on northbound US 93, and other enhancements designed to accommodate projected traffic growth over the next two decades.
