It happened at 11:15 a.m. near the entrance to the tunnel on the East Boston side.

One of the two lanes was closed for about half-an-hour.

There is some damage to the tunnel ceiling, but there was no structural damage.

The truck,  a 2008 Freightliner owned by McCoy National Lease Inc. of Green Bay, Wisconsin, was towing a trailer owned by Primestar Trucking LLC of Postville, Iowa.

State police say they were alerted to the accident by workers at the highway department’s operations center who saw it happen via a video camera.
