Authorities say most of the crashes are fender benders and no serious injuries have been reported Thursday afternoon.
Arizona Department of Transportation officials say low visibility and the crashes forced the closure of State Route 347 from Interstate 10 to Casa Blanca Road about five miles north of Maricopa.
Gusty winds in the area dropped visibility to 1 mile.
ADOT officials say traffic is backed up for several miles as drivers try to exit the highway and take alternate routes.
