A St. Lawrence Seaway lock caved in blocking passage from Lakes Superior, Michigan, Huron and Erie into Lake Ontario and on to the Atlantic Ocean. A 125-foot section of the wall of Lock No. 7 in the Welland Canal collapsed near Welland, Canada, trapping a ship, the Panamanian-registered Furia. Efforts were being made to fill the lock with water in the hope of freeing the vessel. No injuries were reported, and officials could not estimate how long the seaway will be closed. However, any delays are expected to prove expensive.
