(AP) -- The U.S. Coast Guard is expected to continue ice-clearing efforts in southern Lake Huron.

Vessel traffic near the upper St. Clair River is expected to continue Tuesday, one day after officials restricted it due to an ice jam above the Blue Water Bridge.

Officials say U.S. and Canadian Coast Guard ice cutters began conducting operations after winds shifted an 11-mile-long section of ice into the commercial shipping channel.

Three freighters had to be freed after getting stuck over the weekend. Two freighters got stuck on Saturday, one for more than six hours. A third vessel, the empty 1,000-foot Presque Isle bound for its home port of Duluth, Minn., was freed Sunday, more than three hours after it got stuck.
