PHOENIX — Arizona’s third diverging diamond interchange recently opened along Interstate 10 in Buckeye.

The new interchange at I-10 and Miller Road comes after construction on the project started in January.

Diverging diamonds allow both directions of cross-street traffic traveling over or under a freeway to move to the other side of the roadway, improving the overall movement of traffic, the Arizona Department of Transportation said in a press release.

It also aims to enhance safety as traffic conflict points would be minimized, while also allowing direct left turns onto a freeway entrance ramp.

All ramps connecting at I-10 and Miller Road have also opened.

The latest diverging diamond, part of the I-10 widening project, was funded in part by Proposition 400, a voter-approved sales tax in 2004.

The widening project will broaden eight miles of the I-10 from two to three lanes in each direction between Verrado Way and State Route 85.

Crews working on the I-10 project in Buckeye will also reconstruct the Watson Road interchange into a diverging diamond this fall.

Temporary ramp closures will be imposed along Watson Road at I-10 as work moves forward.

The $82 million I-10 improvement project was launched in July 2021 and is on schedule to be completed by summer 2023.
