The Arizona Department of Transportation was about halfway finished with a new connection between Interstate 40 and US 93 in west Kingman in September 2025.

Getting to Las Vegas will soon be much faster — that’s because the Arizona Department of Transportation is at the midway point of building a highway interchange between Kingman and Las Vegas.

Garin Groff is a spokesman for ADOT.

“By the end of the project, a lot of new features will be available all at once, including additional lanes and I-40 and on US 93 plus one mile of new ramps between those two highways, Groff said.

Groff says the 6 miles of new and widened roadway will be completed sometime in 2027.

Portions of US 93 will see intermittent nighttime closures.

According to ADOT, the project will also 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.
