The Arizona Department of Transportation will install dust sensors, warning signs and variable-speed-limit signs along a deadly stretch of Interstate 10.
The warnings will be installed by early 2019 from milepost 209 near Eloy to milepost 219 near Picacho Peak. The interstate there is flanked with degraded desert and fallow farmland where localized “dust channel” storms have caused numerous fatal crashes over the years.
