Winona, Minn. (AP) — Just two years after a bridge in southern Minnesota was closed for repairs, transportation officials found similar problems.
Minnesota Department of Transportation officials said corrosion was found in several gusset plates in the Mississippi River Bridge at Winona. Those are the same structural components that caused the bridge’s sudden close on June 3, 2008.
MnDOT spokeswoman Jessica Wiens said the problem is less severe than the problem two years ago.
A more extensive inspection of the 70-year-old bridge is planned for this month. The bridge is scheduled for a replacement or major overhaul in four years.
Underdesigned and corroded gusset plates were determined to be a major cause of the I-35W bridge collapse.
