The Arizona Department of Public Safety says a single-car rollover in the northbound lanes sent four people to the hospital. The crash impacted southbound lanes, it appears.
Troopers say two children were among those hurt in the crash, and both were hospitalized in critical condition.
However, they were not found at the scene. Someone had driven the affected family to a Circle K near 43rd Avenue and Thomas to get help - five miles away from the crash site.
The right and left lanes have reopened.
