Coast Guard Waterway Closures

US Coast Guard

SAULT STE. MARIE, MI – Captain of the Port Sault Sainte Marie will close three regional waterways inconjunction with the scheduled closure of the Soo Locks. Tuesday 19 January the West Neebish Channel and Pipe Island Channel (North and East of Pipe Island) of the St Marys River and Grays Reef Passage in the Straits of Mackinac will close to commercial shipping due to expected ice growth.

The St Marys River’s Middle Neebish Island Channel and Pipe Island Course will become alternating one-way transit routes. Per United States Code of Federal Regulation, these actions steer commercial shipping and Coast Guard ice breaking activity away from these waterways during the winter months.

A similar announcement in the spring will precede the planned reopening of these waterways.

The Coast Guard reminds all recreational ice users to plan their activities carefully, use caution on the ice, stay away from active shipping routes and ice breaking areas.
