BOSTON (AP) – The family of a woman who was killed when 12 tons of concrete ceiling panels in a Big Dig tunnel collapsed onto her car filed a wrongful death lawsuit Tuesday against the Massachusetts Turnpike Authority and contractors that worked on the massive highway project.

In the lawsuit, the husband and oldest daughter of Milena Del Valle, 39, accuse the authority and various construction and design firms of negligence in her July 10 death. The lawsuit, filed in Suffolk Superior Court, does not seek a specific amount in damages.

“It’s hard to imagine a worse set of circumstances, where someone is simply driving along and 3,000- or 4,000-pound concrete slabs, which are negligently affixed to the ceiling, fall down, crushing an individual to death while her helpless husband is unable to extricate her and finally manages to squeeze out of a 12-inch space himself as she suffers a painful death,” said Boston Jeffrey Denner, who represents Del Valle’s husband, Angel.

“We are seeing a systemic problem where corporations, including multinational corporations, consider the bottom line/profit margin more important than the public’s right to safety,” Denner said.

The Del Valles were driving to Logan International Airport when part of the concrete ceiling of the Interstate 90 connector tunnel collapsed, killing Milena Del Valle instantly. Angel Del Valle escaped by crawling out a window.

Del Valle’s death prompted tunnel and road closures and sparked a public furor over the $14.6 billion Big Dig project, which has been plagued by leaks, falling debris, delays and other problems linked to faulty construction.
