Romney and the Big Dig

Federal officials now say they're looking into the possibility that some of the bolts in the Interstate 90 connector tunnel where falling ceiling panels killed a woman last week, were never inspected after their installation in 1999.

Meantime, crews are now installing new systems to reinforce the fixtures supporting concrete ceiling panels. Governor Mitt Romney hopes to have a ramp linking South Boston to the Ted Williams tunnel open by next week.
