A ship many are used to seeing in Sturgeon Bay ran aground in the St. Marys River this week.
The Paul R. Tregurtha has since been freed, but the U.S. Army Corps of Engineers has sent crews to the river to clear the channel near Sault Ste. Marie, Mich., so shipping can resume. A significant shoal developed in the channel following recovery operations.
The 1,013-foot ship ran aground Wednesday and was freed Thursday.
At least 11 vessels were delayed by the grounding incident.
The Tregurtha, owned by Interlake Shipping Co. of Richfield, Ohio, often winters in Sturgeon Bay. The ship was carrying about 62,000 tons of coal.
