MARANA (KGUN9-TV) - An overturned box truck has closed westbound I-10 in Marana at Cortaro Farms Road, according to the Arizona Department of Transportation.

Northwest Fire Capt. Adam Goldberg said the driver of the truck was evaluated and treated for minor injuries at the scene.
The box truck was carrying non-hazardous cargo, said Goldberg.
There is no estimated time to reopen the highway. Drivers should expect delays and plan alternate routes.
