Interstate 17 in northwest Phoenix reopened Friday morning after being closed for about seven hours because of a crash that the state Department of Public Safety said may have involved vehicles racing on the freeway.
The closure of southbound I-17 between Northern and Southern Avenues because of the crash that occurred at about 2:30 a.m. lasted through the morning commute and caused major backups.
Trooper Kameron Lee saids two of three vehicles involved in the crash may have been racing prior to the collision and that one of the three vehicles rolled, ejecting the female driver who has life-threatening injuries.
The frontage road in the closure area remains open but the Arizona Department of Transportation advised drivers to take alternative routes such as State Route 51.
