In March 1997, the Ohio River crested at 57.52 feet in Huntington - the 5th highest crest since the floodwall was built. Dozens of roads were closed, including two lanes on Interstate 64. Two St. Mary's Hospital nurses died while driving home along Twelvepole Creek. The flooding - which lasted almost a week - brought all other activities in the Tri-State to a halt. Milton, Wayne and Lawrence County, Ohio, were particularly hard hit, though no area in the Tri-State was spared. Cars were washed away. Homes were swamped with mud.
