The families of three immigrant construction workers who died in the Baltimore bridge collapse earlier this year plan to sue the ship owner and operator after they attempt to limit their liability. The bridge collapsed when the cargo ship Dali, which had experienced multiple power failures, collided with a pier while departing from Baltimore Harbor. They are joining a lawsuit previously filed by the U.S. Justice Department, which accuses the shipping company, Grace Ocean, of negligence. The families and city officials argue against the limited liability claim and emphasize that the ship was unseaworthy at the time of the accident.
