Drivers in the West Valley have a reconstructed interchange to use along Interstate 10 in Buckeye.

All ramp connections at I-10 and Miller Road have been opened as a Diverging Diamond Interchange following reconstruction work that started in January, the Arizona Department of Transportation announced Tuesday.

ADOT is widening 8 miles of I-10 from two to three lanes in each direction between Verrado Way and State Route 85 while also reconstructing the interchanges at Miller and Watson roads.

The $82 million I-10 improvement project is scheduled to be done next summer.

The I-10/Miller Road interchange is the third full diverging diamond to be added along the state’s highway system, transportatin officials said in a release.

DDIs also have been constructed at I-17 and Happy Valley Road in north Phoenix and along I-10 at Houghton Road in the Tucson area.

Diverging diamonds allow the two directions of cross-street traffic traveling over or under a freeway to shift to the opposite side of the roadway.

"The crossing is designed to improve the overall movement of traffic and enhance safety by limiting potential traffic conflict points and allowing direct left turns onto a freeway entrance ramp," an ADOT release stated.

It keeps drivers from having to wait at a traffic signal or crossing in front of opposing traffic when making  left turns.

Crews on the current I-10 project in Buckeye are slated to ramp up the reconstruction of the Watson Road interchange as a DDI this fall.

Drivers can expect temporary ramp closures and restrictions along Watson Road at I-10 as the work moves forward, officials said.
