PROJECT:
The Michigan Department of Transportation (MDOT) is investing about $422,000 to build a queue detection and warning system, and make freeway lighting upgrades on the approach to the International Bridge on northbound I-75 in the city of Sault Ste. Marie, Chippewa County. Landscaping and system testing and activation will be completed in spring 2021.

The project map is available on Mi Drive.

TRAFFIC RESTRICTIONS:
The project will require intermittent closures of the outside lane on both northbound and southbound I-75 from the 3 Mile Road overpass to the Easterday Avenue overpass. Work on this segment will require 12-foot width restrictions on northbound and southbound I-75. One lane will be open in each direction at all times.

SAFETY BENEFITS:
This project will implement vehicle detection to activate warning flashers when traffic is backing up on I-75. Lighting upgrades will also increase safety and visibility in the area.
