A wall partially collapsed in the tunnel, I would hazard a guess water seeped through, froze and melted, and weakened the wall or ceiling, causing the collapse. One article I read say they might literally 'pull back' the roof of the tunnel in the collapsed section, though from the pictures I have seen of that tunnel that seems pretty hard to imagine doing.
