3 injured in head-on crash on 495 in Chelmsford
CHELMSFORD - Route 495 northbound in Chelmsford was shut down for about two hours Wednesday after a violent head-on crash that injured three people.
Massachusetts State Police said a car crossed over from the southbound side of the highway into the northbound lanes and crashed into another vehicle just before 10 a.m.
The northbound side was closed at the rest area and traffic was backed up to Route 2A in Littleton for about two hours.
The southbound side was shut down briefly so the driver of one of the cars, a 75-year-old man from Ayer, could be taken away on a medical rescue helicopter. His passenger, a 75-year-old woman from Ayer and the driver of the other car were also taken to the hospital.
The cause of the crash is under investigation. No charges have been filed.
