According to preliminary information, the crash occurred near mile marker 72 in Littleton, where the Massachusetts State Police responded around midday to reports of a serious motor vehicle collision.
Because of the severity of the incident, a medical helicopter was dispatched to transport at least one injured person to a trauma center. Firefighters, emergency medical personnel, and state troopers remained at the scene to provide medical care, investigate the crash, and clear damaged vehicles from the roadway.
Multiple northbound lanes were temporarily closed during the emergency response, leading to substantial traffic congestion. Motorists experienced extended delays as traffic backed up for several miles while first responders worked to safely manage the incident.
