DULUTH, Minn. – A crumbling 1.5-mile bridge carrying heavy truck traffic from Minnesota to Wisconsin has been awarded $1.05 billion via a grant from the Infrastructure Investment and Jobs Act.

Work is expected to begin in 2027 on the four-lane bridge, which crosses the Saint Louis River, a tributary of the Lake Superior, connecting Duluth, Minn. with Superior, Wis.

The bridge serves more than 35,000 vehicles per day, many of them trucks using the route as a critical supply chain thoroughfare.

Built in 1961, the bridge began limiting trucks to only those with a weight of under 40 short tons to try to prevent further deterioration of the span.

The project will be delivered via design-build by a partnership of Minnesota DOT and Wisconsin DOT.
