John A. Blatnik Bridge, Interstate bridge between Duluth, Minnesota and Superior, Wisconsin, United States
The John A. Blatnik Bridge stretches 7,975 feet across Saint Louis River, rising 120 feet above water to allow passage of large vessels underneath.
Opening in December 1961, the bridge received its current name in 1971 to honor Congressman John Blatnik, who supported the Saint Lawrence Seaway project.
The bridge stands as a primary connection point between Minnesota and Wisconsin, serving as a vital transportation link for 33,000 daily commuters.
Vehicles weighing over 40 tons must use alternative routes, as weight restrictions protect the structural integrity of this major crossing point.
In 2024, federal authorities allocated 1.06 billion dollars to replace the aging structure with a new bridge featuring a shared-use path.
