Interstate 10 is closed again between Willcox, Arizona and Lordsburg, New Mexico, according to the Arizona Department of Transportation.
This stretch has closed several times in recent weeks due to winds kicking up dust on a farm.
ADOT said it has communicated with the land owner and is working to get the dust under control.
The area will be closed until wind dies down.
The detour is a 110-mile route through Safford via U.S. 191 and U.S. 70.
