The Madeline Island ferry plans to resume running on Friday. Most traffic across Lake Superior between Bayfield and Madeline Island is either via the ferry or, in the depths of winter, the ice road. But when the ice is either breaking up or settling into its winter thickness, people can get across only by the wind sled - an enclosed boat-hulled craft with huge fans on the back that push the vehicle across the shifting ice.. The wind sleds are usually in action for 10 to 14 days at the beginning of winter and about a week in the spring, though the duration varies each year.

On March 13, 2020 the USCG Alder is in Duluth, Minnesota.
Once icebreaking begins, it is recommended that all recreational users of the ice – pedestrians, fishers, snowmobilers, all-terrain vehicle (ATV) operators – leave the ice during icebreaking operations.
The ice may move, creating a real danger for anyone on the ice. Additionally, they should plan their activities carefully and use extreme caution after operations are complete as the ice will remain unstable after the icebreaker has left the area.
Coast Guard icebreaking service on the Great Lakes and connecting waterways is delivered in close co-operation between the Canadian and United States Coast Guards. By working together the two Coast Guards ensure scheduled vessel traffic can move through the shipping channels and into and out of community harbours.
