I-75 Business Spur project in Sault Ste. Marie wraps up for the season
November 7, 2019 -- All lanes on the I-75 Business Spur (BS) and the new roundabout in Sault Ste. Marie are now open.
Crews have completed asphalt paving on the Michigan Department of Transportation's (MDOT) ongoing reconstruction and roundabout project. Some intermittent lane and shoulder closures over the next few days may be required to finish minor work items. Work on the project is scheduled to be suspended for the season on Nov. 15.
Major construction is now complete, but some work, including tree planting, landscaping, turf establishment, and other punch list items will be completed next construction season.
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 began in May 2018 and is expected to be completed in spring 2020. This project is expected to improve safety and traffic flow in this area.
