Maryland State police say a chain-reaction crash shut down the Baltimore Beltway's Outer Loop at southbound Interstate 83, causing traffic to be backed up for miles.

Police tell local media outlets that 13 vehicles were involved in a crash around 9:20 p.m. Monday after one vehicle hit a wall and became disabled in the roadway. Other vehicles then collided.

The collision involved a private ambulance that did not have a patient inside and a tractor-trailer that jackknifed.
