A bus carrying ten people rolled-over on the Northway northbound around 3:15 this morning.

State police say that one woman, who is believed to be from New York City, died in the accident. 

The Associated Press reports that Glen Falls Hospital officials say three victims are hospitalized in fair condition and six others were treated and released.

The crash occurred just south of exit 21, the Lake George-Lake Luzerne exit.

The DOT says the northbound lanes were closed but have been reopened.

The bus was operated by a privately owned company, not a major carrier, according to police.

Police crews are currently on the scene and are still not sure what caused the crash.
