MassDOT reports no structural damage to the tunnel but that the exit will be closed indefinitely as crews remove the remains of the truck, fuel and cement.
MassDOT was planning on restricting traffic in the main tunnel to just one lane in either direction this weekend to allow for removal of an old and no longer needed tunnel ceiling.
