November 14, 2018 -- All legs intersecting the new roundabout on the I-75 Business Spur (BS) in Sault Ste. Marie are now open.

Traffic from Mackinac Trail, I-75 BS and Three Mile Road can now access the newly constructed roundabout. The roundabout will be open to one lane of traffic for the winter. Drivers are reminded not to stop in the roundabout. If you hear or see an emergency vehicle approaching, exit the roundabout before pulling over.

Work in the Michigan Department of Transportation's (MDOT) work zone on I-75 BS will continue for the remainder of the week, preparing storm sewer and temporary traffic control devices for the pending seasonal suspension of work.

Weekly progress meetings for the project will be discontinued until spring. MDOT will announce a new meeting schedule before they resume.

MDOT and the City of Sault Ste. Marie are investing $11.2 million to reconstruct 2.2 miles of roadway and construct a roundabout combining the intersections of Three Mile Road/Mackinac Trail and I-75 BS/Mackinac Trail in Sault Ste. Marie. The project is scheduled to be constructed in phases over two years. The project began in May and is expected to be completed in October 2019.

This project is expected to improve safety and traffic flow in this area.
