BOSTON (WHDH) – A box truck rolled over early Friday morning, blocking multiple lanes in Boston’s O’Neill Tunnel near the entrance to the Mass Pike.

The truck overturned on the northbound side of the Expressway. It has since been cleared from the tunnel and all lanes have been reopened.

Traffic lingered for much of the morning commute. At one point, cars were backed up for more than 10 miles.

MassDOT traffic cameras captured the moment the truck flipped over. The video shows two other trucks braking and the driver swerving before toppling over.

State police said the driver was not injured and no other injuries were reported.
