Route 2 West is closed in the area of exit 16 on the Marlborough-Colchester line after a rollover.
State police are diverting traffic off at exit 16, so drivers will have to use Old Hartford Road, which runs parallel, and get back on the highway at exit 13.
Traffic was already slow because of an ongoing paving project set up in the area, so expect delays.
No additional information is immediately available.
