An overturned tractor-trailer sent traffic crawling Wednesday into early Thursday morning in the outer loops of the Beltway near Landover and police have not yet released the cause of the accident.
The crash was reported in the median strip in the area of Central Avenue around 9 p.m. Wednesday. At one point, the crash shut down three lanes on both sides, putting traffic to a halt in both directions. Around midnight, two lanes reopened on each side but fuel cleanup by a hazmat crew continued into Thursday.
Police have not yet released the cause of the accident but say the crash involved the tractor-trailer and one car.
