Well, as if Bostonians haven't gone through enough with this whole Big Dig fiasco, another story has been outed by the Boston Globe today about how I-93 tunnels are now being called unsafe. Jack Lemley, who has been the big engineering honcho specifically dealing with the new tunnels, released a letter on March 9, revealing that he now feels that maybe they aren't that safe after all. (This is the same man who went to Beacon Hill this past fall and convinced lawmakers that they were completely safe.) Lemley claims he's changed his mind after the recent discovery of leaks throughout the tunnels; adding to that, he says the Massachusetts Turnpike Authority won't allow him to see records and data pertaining to these leaks, and that they don't even have a clue as to what they are going to do to stop them. Of course this has riled up the boys over at the MTA even more; Authority Chairman Matthew Amorello claims he hasn't gotten the letter yet and remains to stand by the idea that the tunnels are safe. What's Beacon's Hill take on all this? Gov. Romney has previously asked for Amorello to step down since all these problems started. Amorello refuses to and here we all go again. One big circus, otherwise known as "The Big Dig."
