Big Dig Investigations

There are more problems with bolts holding up ceiling panels in a big dig tunnel.

Officials have closed one westbound lane of the Ted Williams tunnel after finding three loose bolts.

A special temporary support is being put in place. Officials say it could take several days to reach a permanent fix.

Meantime, more than a half-dozen investigations into the fatal ceiling panel collapse earlier this month continue.

And some state lawmakers say they might introduce a bill as early as today, to create an emergency review board to look into the big dig.

The panel would investigate as the proposal says "unsafe and corrupt practices on the Central Artery Project" but, as Monica Brady-Myerov reports, not everyone supports the call for another inquiry.
