Highway 89 was closed for most of Wednesday between Flagstaff and Page, just south of Cameron, for a multi-vehicle accident. DPS officials say the accident happened just after noon Wednesday after three-vehicles collided. A black Dodge Journey was heading northbound on Highway 89, four miles south of Gray Mountain. The Journey crossed the double yellow lines and collided with a Penske moving truck and another pickup truck heading southbound. Two people in the southbound vehicles were seriously injured and were transported to Flagstaff Medical Center. The driver, 25-year-old Joshua James Burbank from Chinle, was arrested at the scene. He has been booked into the Coconino County Jail in Flagstaff on charges of aggravated assault and DUI.
