TUCSON, Ariz. (AP) - The Arizona Department of Public Safety is on the scene of a rollover accident on eastbound Interstate 10 near Benson in southern Arizona.

The accident 16 miles east of Benson has blocked one lane and traffic in the area is moving very slowly. The accident is expected to be cleared by noontime Wednesday.

The collision occurred when a tractor trailer and a '89 Isuzu Trooper traveling in the same direction, side by side, came into contact with each other causing the truck to go into the median and the trailer it was pulling to rollover.

One person was taken to a hospital in Willcox for treatment.
