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.

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.
