Mass. Settles Over Big Dig Collapse

The Massachusetts attorney general has settled with a Big Dig contractor over the 2006 collapse of a tunnel ceiling, concluding all litigation in an accident that killed a Boston woman.

Attorney General Martha Coakley said in a statement Thursday that designer Gannett Fleming has agreed to pay $1.5 million into a Central Artery maintenance trust fund.

The company will also pay $50,000 to the city of Boston and forgo $150,000 in payments from the Massachusetts Turnpike Authority.

Coakley has also reached a settlement agreement with Sika Corp. It made the epoxy glue used in the ceiling that collapsed. Sika, in turn, sold the product to Powers Fasteners Inc., which has already settled.

Sika has agreed to pay $200,000 into the trust fund, which is being used for upkeep on the $15 billion tunnel complex.
