UPDATE (3:49 pm): State Police report the left travel lane is now open to traffic.

Massachusetts State Police report a serious accident on Route 195 Eastbound near Exit 11 in Dartmouth Thursday afternoon.

The call came in shortly before 2 p.m. of a single-vehicle rollover crash near the Reed Road exit. State Police report that 195 East is closed in that area in order to allow for a MedFlight helicopter, as one of the victims has sustained life-threatening injuries.

We will have more details as they become available.
