Four people were injured in a three-vehicle crash on Interstate 19 in Green Valley late Thursday afternoon, authorities said.

A van rolled in the June 29 crash, said an Arizona Department of Public Safety official.

The crash occurred at kilometer 57, said L.T. Pratt, a Green Valley Fire District spokesman.

Firefighters and medical personnel treated the injured, including two minors, who were all taken to Banner-University Medical Center Tucson, said Pratt. The injuries are non-life threatening.

All were wearing seat belts, Pratt said.

Motorists were asked to drive cautiously and avoid the area. Lanes on the interstate are restricted.
