Maryland State Police said the woman lost control of her vehicle about 9: 30 p.m. Police said no passengers were in the car.

It was not known whether anyone in the tractor-trailer was injured. The woman was pronounced dead at the scene.

The accident closed northbound I-83 between Northern Parkway and Ruxton Road for several hours and backed up traffic for about two miles.
