The West Kingman I-40/US 93 interchange is much further along, and you can see it from the road.
ADOT says the $106 million project is about 80 percent complete as of early September 2026. That is a clear step up from the halfway mark the agency reported in September 2025.
The newest visible win is a new tunnel now open on the job. The 239-foot tunnel carries northbound Beale Street traffic from downtown Kingman and I-40 toward northbound US 93 for Las Vegas. ADOT calls it the project’s second tunnel and the one that will handle the most traffic. The first tunnel, about 215 feet long for Fort Beale Drive local traffic, opened in September 2025.
The point of all this is still the same free-flowing interchange plan. Drivers will not have to stop at the Beale Street signal at I-40 the way they do now. About one mile of new ramps is meant to let traffic move between I-40 and US 93 without that light.
What else is done: rock blasting along I-40 is finished, and sound wall work along I-40 is wrapped up. What is still moving: paving on those new mile-long ramps between I-40 and US 93.
Next up on the calendar, ADOT is preparing to set the final bridge girders on the flyover that will connect southbound US 93 with eastbound I-40. That girder work is expected in October 2026.
Daytime and nighttime work and lane restrictions are still part of the deal. Beale Street exits from I-40 and US 93 stay open for downtown, Route 66, and local businesses while construction continues.
ADOT still points to a 2027 opening for the finished interchange, with about 6 miles of widened or newly built roadway in the package. The job also includes new and rehabbed bridges plus sound walls. Construction started in July 2024.
If you are watching the work zone week to week, az511 and ADOT’s West Kingman TI page remain the place for live pattern changes. The big picture for September 2026 is simple: second tunnel open, rock work and sound walls done on I-40, ramps getting paved, flyover girders next, free-flow still aimed at 2027.
