Courtney Ann Sanford, 32, killed, after her car crashes into a metal recycling truck on Business 85 in Greensboro.

A woman was killed in a fiery crash involving a large truck that shut down Business 85 south Thursday morning.

Courtney Ann Sanford, 32, of Clemmons, died at the scene of the crash around 8:30 a.m. near Baker Road. The truck driver wasn't injured.

Sanford's 2005 Toyota Corolla was going north on Bus. 85 when it crossed the median and hit a metal recycling truck heading southbound, police said. The truck ended up hitting a tree.

The car's flames were quickly extinguished, police said. No one else was in either vehicle.

The cause of the crash is still being determined. Impairment has been ruled out, and the estimated speed of impact was 45 mph, police said.

Both southbound lanes remained closed for more than three hours, and one northbound lane was also closed at one point.
