ELOY – Arizona officials are installing a system along Interstate 10 between Phoenix and Tucson to warn drivers about dangerous dust storms.

The system of radar, cameras and electronic message boards is being installed along a 10-mile stretch of I-10 where it meets State Route 87, southeast of Eloy. The system is part of construction to improve the SR87 interchange and widen a portion of I-10.

Tom Herrmann, a spokesman with the Arizona Department of Transportation, said this busy stretch of freeway has had the most fatal accidents because of dust storms.

“It’s a very important section for the two largest metropolitan areas in (Arizona) when people are driving back and forth, so this will help millions of people,” Herrmann said.

“When you see a dust storm, and you can’t see where you’re going, pull off the highway. ‘Pull aside, stay alive.’ That’s been our mantra for the past seven or eight years, and we really think that’s going to continue to be an important part of this.”

The detection system is scheduled for completion in September 2019. In addition to the detection system, ADOT plans to add more cameras along the freeway to better monitor east- and westbound traffic.
