A Jasper teen died the day after the car they were driving Saturday struck a pothole and left the road before hitting a concrete bridge rail in Walker County, authorities said Tuesday.

The 18-year-old victim, whose name was not publicly released, was driving a 2011 Nissan Sentra around 9:50 p.m. Saturday on Whitehouse Road near Industrial Parkway near Jasper when the vehicle struck a pothole, according to Alabama Law Enforcement Agency Senior Trooper Brandon Bailey.

After the initial impact, the car left the road and then struck a concrete bridge rail.

The driver, who was not wearing a seat belt during the crash, was taken to a local hospital for treatment.

On Sunday, the teen died of their injuries, Bailey said.

The crash, about a mile south of Jasper, remained under investigation Tuesday.

Further information was unavailable.
