BOSTON (CBS) – Calls have begun for new safety inspections after WBZ-TV broke the news that the Big Dig soil around the I-90 connector tunnel that was frozen during construction for stability, is now sinking twice as quickly as engineers expected.

There is now a hole under the tunnel that 50,000 driver use every day.

The state says there is no danger.

“This is something that has been talked about with the board a long time ago again a report given to the board the other day letting the public know the important thing is their safe their being monitored and ultimately will be repaired,” said Lt. Gov. Tim Murray.

But on Friday, Congressman Stephen Lynch said at the very least, some reassurance was in order.

“I have requested that both the Massachusetts Department of Transportation and the Federal Highway Administration conduct a thorough inspection and structural assessment of the affected area. The safety of the public must be our top priority,” said Congressman Lynch.  “I know that they’re saying that the public is not at risk but I would want to look deeper into that and try to find out structurally the problem is. I don’t want to have someone come up and glibly say there’s no threat to the public. We would want to have a full investigation.”

The Acting Highway Chief, Frank DePaola has said the soil problems won’t affect the tunnel, in part because it was built to act as a bridge.

    This is asinine!!!!! Shoddy construction, shady deals, billions of dollars spent…

    I believe there’s a couple of bridges built in the 1930’s connecting to the Cape that is probably in better condition than the Habitrail these people built 10 years ago…

    Now, I didn’t do all that great in phsysics in school, but a bridge is either held up by wire systems (Zakim) or by repeated pillars below, ex the bridge to Prince Edward Island

    These tunnel sections have neither. They are supported entirely by the soil below them. Which is now melting away

    The sections are if I recall the programs, fairly long.

    If you take away the support at either end, the middle or a mix of the two, you are straining the concrete walls, ceiling and floors

    Strain them and they give. Not collapsing, but cracking, stretching, squeezing etc.

    Mix that with 1000 lbs roof plates, which have already fallen in the past and you tell me that there aren’t any safety concerns and or issues ?

    Are you f@#^Y@ kidding me ?

    Take a piece of painted wood. Lift it in both ends and if long enough, it will bend in the middle and the paint will crack. Lift it in the middle and the ends will bend and the paint will crack

    We are talking about massive and extremely heavy tunnel sections, with people driving in them and not to mention subway trains above them

    Yeah nothing to worry about at all.

    Another nail in the coffin against wanting to voluntarily enter the city of Boston for any reason, by some tolerable or safe commuting method, save possibly by means of hot air balloon or helicopter. :-o
