MassDOT has launched emergency inspections inside the Prudential Tunnel after concrete came crashing down on unsuspecting motorists.

NO injuries were reported but the accident set of a chain reaction that has snarled traffic in the city.

“This afternoon, a section of non-structural concrete at an expansion joint below Huntington Avenue became dislodged and fell into a travel lane in the Prudential Tunnel,” MassDOT said. “Recent freeze/thaw cycles caused the concrete to become saturated, freeze, and then delaminate as temperatures rose today.”

This is a developing story and here is the video MassDOT provided:
