New Diverging Diamond Interchange opens at Interstate 10 at Miller Road

The Interstate 10: State Route 85 to Verrado Way Improvement Project will hit a milestone as the Arizona Department of Transportation reopens the I-10/Miller Road Traffic Interchange as a Diverging Diamond Interchange (DDI) today, Aug. 22.

The work on the Miller Road interchange began in January, with the reconstruction of the westbound off-ramp and the eastbound on-ramp; the next phase reconstructed the remaining two ramps; and finally the third phase of the interchange completed the freeway bridges over Miller Road.

This is the third full DDI to be added along the state highway system. ADOT previously has added DDIs at I-17 and Happy Valley Road in Phoenix and at I-10 and Houghton Road in Tucson. A DDI is a diamond interchange where the two directions of traffic on the street crossing over or under the freeway are temporarily shifted to the opposite side of the roadway via intersections and traffic signals. Diverging diamonds, which have grown in popularity across the country, are designed to limit traffic conflict points and crashes compared to traditional intersections, while also enhancing the overall movement of traffic.

This animated video demonstrates how the new interchange is configured and how the traffic will travel through it.
