Issues: The bridge is reaching the end of its design life. The Winona bridge was one of 25 bridges with a design similar to I-35W bridge that underwent inspection. In June the bridge closed after inspectors discovered rust and corrosion in some of the gusset plates. The gusset plates have since been repaired and strengthened.
