Both spans took major hits from high waters during Katrina. Roadways were lifted off their foundations by the storm. The overpasses were undamaged. Boh Brothers construction won the approval of the populace and a $1.3 million bonus for reopening the Eastern span 17 days ahead of schedule. The other span will be ready around the first of the year.

There is now talk of additional 3 lane spans built a bit higher to avoid a repeat performance.

Suprisingly the old US-11 bridge and the railroad bridge just to the west of the Twin Spans were not seriously damaged. The US-11 bridge briefly resumed it role after the storm providing the primary access to Slidell.
