October 31, 2018 — The traffic configuration is set to change in the Michigan Department of Transportation’s (MDOT) work zone on the I-75 Business Spur (BS) in Sault Ste. Marie.
Beginning Friday, Nov. 2, traffic from Mackinac Trail will be able to access the I-75 BS using the newly constructed roundabout. At the same time, Three Mile Road will be closed at the roundabout while the roadway is reconstructed and tied into the roundabout. Motorists can access Three Mile Road from M-129.
The traffic change will begin Friday afternoon. This phase of work is expected to be completed by mid-November.
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.
